Inflammatory disorders are one of the most important health problems in the world Inflammation is in general a localized protective response of the body tissues to invasion of the host by foreign material or injurious stimuli The causes of inflammation can be infectious agents such as bacteπa, viruses, and parasites, or physical agents such as burns or radiation, or chemicals like toxins, drugs or industrial agents, or immunological reactions such as allergies and autoimmune responses or conditions associated with oxidative stress

Inflammation is characterized by pain, redness, swelling, heat, and eventual loss of function of the affected area These symptoms are the results of a complex senes of interactions mainly taking place between the cells of the immune system The response of the cells results in an interacting network of several groups of inflammatory mediators Proteins (e g .cytokines, enzymes [e g ,proteases, peroxydase], major basic protein, adhesion molecules [ICAM, VCAM]),

lipid mediators (e.g.,eicosanoids, prostaglandins, leukotrienes, platelet activating factor [PAF]), reactive oxygen species (e.g. hydroperoxides, superoxyde anion O 2 " , nitric oxide [NO] etc). However, many of those mediators of inflammation are also regulators of normal cellular activity. Thus, deficiencies of inflammatory reactions lead to a compromised host (i.e. infection) while uncontrolled and thus chronic inflammation leads to inflammatory diseases mediated in part by the excessive production of several of the above mentioned mediators.

Acute and chronic inflammation resulting from an excessive biosynthesis of inflammatory mediators is involved in numerous inflammatory disorders such as arthritis (e.g. osteoarthritis, rheumatoid arthritis), asthma, inflammatory bowel diseases, inflammatory diseases of the skin (e.g. contact dermatitis [particularly diaper area dermatitis], atopic dermatitis, xerosis, eczema, rosacea, seborrhea, psoriasis, neurodermitis, acne, thermal and radiation burns such as sunburn,) and chronic inflammatory disorders, such as atherosclerosis, heart diseases, metabolic syndrome X, cancer, Alzheimer's disease and pre-stages thereof such as mild cognitive impairment or photoageing which is which is associated with chronic skin inflammation.

Rheumatoid arthritis is a chronic inflammatory disease of the joints and is one of many different forms of arthritis. For example, arthritis includes rheumatoid arthritis, spondyloarthopathies, gouty arthritis, osteoarthritis, systemic lupus erythematosus and juvenile arthritis. Like asthma, rheumatoid arthritis is characterized at the molecular level by chronically unbalanced expression of cytokines, chemokines, kinins and their receptors, adhesion molecules and their respective receptors, as well as inflammatory enzymes.

Psoriasis is one of the most common skin problems, affecting 1-3% of the human population. Inflammatory bowel disease is a general term used to describe gastrointestinal tract diseases and includes disorders such as ulcerative colitis and Crohn's disease.

Beside the process of intravascular lipid deposition, inflammatory reactions of the endothelial (i.e. blood vessel) wall are considered to critically contribute to atherosclerosis i.e. atheroma formation. Atherosclerosis results from vascular injury which triggers inflammation. Activated macrophages, T-lymphocytes, and eventually smooth muscle cells are present in atherosclerotic plaques. Monocyte/macrophage and lymphocyte activation leads to the release of eicosanoids, cytokines and matrix metalloproteinases (MMPs) which are implicated in endothelial damage, as well as in the formation and eventually the rupture of atherosclerotic plaques. Finally, circulating inflammatory markers such as C-reactive protein (CRP), fibrinogen, and interleukins are

increased or altered in groups at high-risk of coronary artery diseases (CAD). Several clinical trials indicate that elevated CRP concentration correlates with increased risk of coronary, and vascular events. Thus inflammation appears to play an important role in the initiation and progression of atheroma formation.

Inflammatory processes are also associated with the pathophysiology of Alzheimer's disease. There is evidence of inflammation in the brain of patients with Alzheimer's disease, as it is characterized by increased levels of cytokines and activated microglial cells. Thus, inflammation is not only involved in the classical inflammatory disorders (e.g., arthritis, asthma, bowel diseases) but is also associated with many chronic inflammatory disorders (e.g., atherosclerosis, heart diseases, metabolic syndrome X, cancer, Alzheimer disease).

Inflammatory events are also associated with the pathophysiology of different types of cancers (e.g. gastric and intestinal cancers, melanomas). Increased levels of inflammatory mediators such as prostaglandins have been found in cancers of breast, colon, lung and pancreas in humans.

Currently, two main classes of drugs, the corticosteroid and the nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat inflammatory disorders. NSAIDs and corticosteroids provide essentially symptomatic relief. Use of corticosteroids has declined due to a growing concern about the serious side effects of prolonged use.

NSAIDs are among the most widely used drugs, primarily for the treatment of pain and inflammatory disorders, in particular for the treatment of arthritis (i.e. pain relief). Epidemiological studies have suggested that patients taking NSAIDs have a lower risk of developing Alzheimer's disease than those not taking NSAIDs. A protective effect of NSAIDs suggests that the cyclooxygenases might be involved in the neurodegenerative process. Epidemiological studies showed a significant reduction in the risk of colorectal, gastric, esophageal, and breast cancers among people who take NSAIDs compared with those not taking NSAIDs. In animal models, NSAIDs significantly reduced tumor development.

However, long-term use of NSAIDs when treating chronic diseases such as arthritis, is limited by severe side-effects like serious gastrointestinal complications, renal toxicity or asthmatic reactions.

Therefore, there is a need for new anti-inflammatory agents with weak or no side effects. Patients with inflammatory diseases have a special interest in a type of treatment considered as "natural" with mild anti-inflammatory effects and without major side effects, which can be used for disease prevention and as adjuvant treatment. Furthermore, the treatment used needs to maintain the equilibrium between excessive and insufficient inflammatory reaction.

There are many known examples of such "natural" agents with shown anti-inflammatory action. However, a disadvantage of these "natural" compounds is that their biological and thus inhibitory activity is often inadequate. When two or more natural substances are applied concomitantly, their action can be additively or even synergistically enhanced. This lowers the required amount of each substance in order to effect disease development or treatment. Since lower doses of each of the natural substances individually can be used, there is less chance that deleterious levels are reached and also less chance of serious side-effects due to chronic use.

dry composition (for example, kibble), semi-moist composition, wet composition, or any mixture thereof. Alternatively or additionally, the animal feed is a supplement, such as a gravy, drinking water, yogurt, powder, suspension, chew, treat (e.g., biscuits) or any other delivery form.

Dietary supplements of the present invention may be delivered in any suitable format. In preferred embodiments, dietary supplements are formulated for oral delivery. The ingredients of the dietary supplement of this invention are contained in acceptable excipients and/or carriers for oral consumption. The actual form of the carrier, and thus, the dietary supplement itself, is not critical. The carrier may be a liquid, gel, gelcap, capsule, powder, solid tablet (coated or non- coated), tea, or the like. The dietary supplement is preferably in the form of a tablet or capsule and most preferably in the form of a hard (shell) capsule. Suitable excipient and/or carriers include maltodextrin, calcium carbonate, dicalcium phosphate, tricalcium phosphate, microcrystalline cellulose, dextrose, rice flour, magnesium stearate, stearic acid, croscarmellose sodium, sodium starch glycolate, crospovidone, sucrose, vegetable gums, lactose, methylcellulose, povidone, carboxymethylcellulose, corn starch, and the like (including mixtures thereof).

In other embodiments, the present invention provides nutritional supplements (e.g., energy bars or meal replacement bars or beverages) comprising the composition according to the invention. The nutritional supplement may serve as meal or snack replacement and generally provide nutrient calories. Preferably, the nutritional supplements provide carbohydrates, proteins, and fats in balanced amounts. The nutritional supplement can further comprise carbohydrate, simple, medium chain length, or polysaccharides, or a combination thereof. A simple sugar can be chosen for desirable organoleptic properties. Uncooked cornstarch is one example of a complex carbohydrate. If it is desired that it should maintain its high molecular weight structure, it should be included only in food formulations or portions thereof which are not cooked or heat processed since the heat will break down the complex carbohydrate into simple carbohydrates, wherein simple carbohydrates are mono- or disaccharides. The nutritional supplement contains, in one embodiment, combinations of sources of carbohydrate of three levels of chain length (simple, medium and complex; e.g., sucrose, maltodextrins, and uncooked cornstarch). Sources of protein to be incorporated into the nutritional supplement of the invention can be any suitable protein utilized in nutritional formulations and can include whey protein, whey protein concentrate, whey powder, egg, soy flour, soy milk soy protein, soy protein isolate, caseinate (e.g., sodium caseinate, sodium calcium caseinate, calcium caseinate, potassium caseinate), animal and vegetable protein and hydrolysates or mixtures thereof. When choosing a protein source, the biological value of the protein should be considered first, with the highest biological values being found in caseinate, whey, lactalbumin, egg albumin and whole egg proteins. In a preferred embodiment, the protein is a combination of whey protein concentrate and calcium caseinate. These proteins have high biological value; that is, they have a high proportion of the essential amino acids. See Modern Nutrition in Health and Disease, eighth edition, Lea & Febiger, publishers, 1986, especially Volume 1, pages 30-32. The nutritional supplement can also contain other ingredients, such as one or a combination of other vitamins, minerals, antioxidants,

fiber and other dietary supplements (e.g., protein, amino acids, choline, lecithin). Selection of one or several of these ingredients is a matter of formulation, design, consumer preference and end- user. The amounts of these ingredients added to the dietary supplements of this invention are readily known to the skilled artisan. Guidance to such amounts can be provided by the U.S. RDA doses for children and adults. Further vitamins and minerals that can be added include, but are not limited to, calcium phosphate or acetate, tribasic; potassium phosphate, dibasic; magnesium sulfate or oxide; salt (sodium chloride); potassium chloride or acetate; ascorbic acid; ferric orthophosphate; niacinamide; zinc sulfate or oxide; calcium pantothenate; copper gluconate; riboflavin; beta-carotene; pyridoxine hydrochloride; thiamin mononitrate; folic acid; biotin; chromium chloride or picolonate; potassium iodide; sodium selenate; sodium molybdate; phylloquinone; vitamin D3 ; cyanocobalamin; sodium selenite; copper sulfate; vitamin A; vitamin C; inositol; potassium iodide.

The nutritional supplement can be provided in a variety of forms, and by a variety of production methods. In a preferred embodiment, to manufacture a food bar, the liquid ingredients are cooked; the dry ingredients are added with the liquid ingredients in a mixer and mixed until the dough phase is reached; the dough is put into an extruder, and extruded; the extruded dough is cut into appropriate lengths; and the product is cooled. The bars may contain other nutrients and fillers to enhance taste, in addition to the ingredients specifically listed herein. It is understood by those of skill in the art that other ingredients can be added to those described herein, for example, fillers, emulsifiers, preservatives, etc. for the processing or manufacture of a nutritional supplement.

A person skilled in the art knows which carriers can be used as pharmaceutically acceptable carriers. Suitable pharmaceutical carriers are e.g. described in Remington's Pharmaceutical Sciences, supra, a standard reference text in this field. Examples of such pharmaceutically acceptable carriers are both inorganic and organic carrier materials, suitable for oral/parenteral/injectable administration and include water, gelatin, gum arabic, lactose, starch, magnesium stearate, talc, vegetable oils, and the like.

The pharmaceutical composition may further comprise conventional pharmaceutical additives and adjuvants, excipients or diluents, including, but not limited to, water, gelatin of any origin, vegetable gums, ligninsulfonate, talc, sugars, starch, gum arabic, vegetable oils, polyalkylene glycols, flavoring agents, preservatives, stabilizers, emulsifying agents, buffers, lubricants, colorants, wetting agents, fillers, and the like.

In a preferred embodiment the pharmaceutical is in the form of a powder, tablet, capsule, gel, liquid or solid embodiment.

The dosages and ratios of the individual components in a pharmaceutical composition can be determined by the expert in the field with normal preclinical and clinical trials, or with the usual considerations regarding the formulation of pharmaceutical composition.

In a preferred embodiment rosehip is administered via a pharmaceutical composition either in the form of a single dose or by multiple doses in an amount of at least 0.3 mg/ kg bodyweight/ day, preferably in an amount of 1-450 mg/ kg body weight/ day, most preferably in an amount of 4- 140 mg/ kg body weight / day based on the weight of dried rosehip concentrate.

The nutraceutical and pharmaceutical according to the present invention may be in any galenic form that is suitable for administering to the animal body including the human body, more in particular in any form that is conventional for oral administration, e.g. in solid form, for example as (additives/supplements for) food or feed, food or feed premixes, fortified food or feed, tablets, pills, granules, dragees, capsules, and effervescent formulations such as powders and tablets, or in liquid form, for instance in the form of solutions, emulsions or suspensions, for example as beverages, pastes and oily suspensions. The pastes may be filled into hard or soft shell capsules. Examples for other application forms are forms for transdermal, parenteral, topical or injectable administration. The nutraceutical and pharmaceutical may be in the form of controlled (delayed) release formulation. Examples of pharmaceuticals also include compositions suitable for topical application such as cremes, gels, sprays, dry sticks, powders etc.

Examples of rosehip include rosehip concentrate, preferably a dried rosehip concentrate, a lipophilic extract of rosehip (including rosehip oil, rosehip seed oil or a fractionated lipophilic extract) or a hydrophilic extract of rosehips (a rosehip extract comprising water-soluble parts of rosehips, such as for instance polysaccharides) or compounds derived from rosehips.

Rosehip extract may be obtained from the fruit, petals and/or seeds from wild rose bushes, such as Rosa canina ("dog rose-hip"), Rosa gallica, Rosa condita, Rosa rugosa, Rosa hugonis, Rosa nitida, Rosa pendulina, Rosa pimpinellifolia, and Rosa sericea. Preferably, rosehip extract is prepared from the fruit (i.e. the rosehip).

Rosehip is a natural product and hence its composition may vary somewhat. The hydrophilic extract e.g. has a high vitamin C content which might be in the range of 0.6 and 1.5 mg per g and contains as well other vitamins and minerals. An example of a rosehip extract is that produced in accordance with the description in US 6,024,960. Of course, the quantities of the specific vitamins and minerals may vary by species or through use of different extraction/concentration methods. An exemplary rosehip extract is shown in Table I (page 4 and 5) of WO 02/342274, however the invention is not limited thereto.

Dried rosehip concentrate can be obtained from dried and milled rosehips that are reduced to powder. A rosehip concentrate may for example be obtained in the following method: Rosehips are harvested in a generally known manner when the hips are fully ripe. Rosehip can be obtained from any of the multiple species of plants that belong to the Rosa family, for example from rosehips from wild rose bushes, such as Rosa canina ("dog rose-hip"), Rosa gallica, Rosa

condita, Rosa rugosa, Rosa hugonis, Rosa nitida, Rosa pendulina, Rosa pimpinellifolia, and Rosa sericea, more preferably hips of Rosa canina are used. After the hips are harvested, the hips are chopped into pieces. If further processing is delayed, the hips may be frozen for storage. In any event, the next step is to dry the chopped rosehips to a water content of about at most 5% by weight. Preferably, the drying is conducted in such a way that the vitamin content of the rosehips is preserved, for example by drying the rosehips at a temperature below 50 0 C with air and by avoiding sunlight.

The dried and chopped rosehips may then be passed through a separation step in which extraneous matter, for instance nuts, hairs etc., that may have accompanied the rosehips during harvesting is removed. The remaining fruit flesh is then crushed in a grinding mill. Preferably, the obtained material has a particle size of below 1 mm, more preferably between 0.1 and 0.5 mm.

Therefore, a process for obtaining a dried and milled rosehip concentrate may comprise the following steps: a) harvesting rosehips when the hips are fully ripe b) chopping the harvested rosehips into pieces c) drying the chopped rosehips to a water content of at most 5% by weight d) optionally passing the dried and chopped rosehips through a separation step in which extraneous matter is removed e) optionally the fruit flesh and the seeds may be separated and extracted separately f) crushing the remaining material in a grinding mill to a particle size of below 1 mm.

Preferably, the extract (fraction) comprises at least cyanidin-3-o-glucoside, cyanidin-3-o- rutinoside or glycosides of diacylglycerol such as 3-beta-D-galactopyranosyloxy-2-(octadeca- 9Z, 12Z, 15Z-trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate (GOPO), in particular at least GOPO.

It has been found that the compositions according to the invention are also suitable for the treatment, co-treatment or prevention of another joint disorder namely cartilage degradation or cartilage damage in joints and as such for treatment of the cartilage degradation component of joint disorders, for example degenerative joints disorders such as osteoarthπtis or sport injuries

Cartilage degradation is defined within the framework of the invention as a metabolic disorder of joint cartilage characterized by increased production of cartilage-degrading enzymes such as matπx metalloproteases

Osteoarthπtis is a chronic degenerative disease of the joint of non-inflammatory origin, which develops by wear and tear of the joints during aging and results in pain and diminished joint function Symptoms of osteoarthπtis include pain, stiffness and loss of mobility in one or more joints Excessive joint loading increases the risk of osteoarthritis, hence osteoarthritis mostly affects the weight-bearing joints such as spine, knees and hips, but thumb and finger joints may also be affected Joint disorders can also results from injury, i e microdamage or blunt trauma, fractures, damage to tendons, menisci or ligaments or can be the result of excessive mechanical stress or other biomechanical instability resulting from for example an injury or obesity

Joint disorders due to cartilage degradation are leading causes of disability and dysfunction in the elderly, almost 80% of people over age 60 show some evidence of these disorders Age, genetic

factors, muscle disuse and weakness, trauma, obesity and anatomical abnormalities contribute to the development of the disorder.

Joint disorders are difficult to treat. Up till now, treatment was largely limited to addressing the symptoms mainly with non-steroidal anti-inflammatory drugs. The drugs are given to control the pain and to restrain swelling, but do not prevent or treat damage to the cartilage. The patients experiencing severe cartilage damage frequently require surgery, including joint replacement surgery. Therefore, there was a great need for agents that treat or prevent cartilage loss and damage, which need has been solved by the present invention.

The composition of the present invention may have one or more of the following properties: it maintains and/or improves joint health, it prevents joint stiffness, it promotes joint mobility, it provides supple and/or flexible joints, it lubricates the joints, it relieves arthritis pain, it lessens joint problems, it provides joint care, it treats or prevents joint degradation, it provides joint integrity, it retards or prevents the progression of joint damage, it supports joint function, it promotes joint health and function, it naturally supports joint health and mobility for active individuals, it maintains the active flexibility of joints, it promotes joint flexibility and promotes joint mobility. Thus, further objects of the present invention are: • Use of a composition according to the invention as cartilage-regenerating and maintaining agent.

• Use of a composition according to the invention for maintenance of joint health.

• Use of a composition according to the invention (for the manufacture of a composition) for the maintenance and regeneration of articular cartilage. ^ A method for the regeneration and/or maintenance of (articular) cartilage in a mammal which comprises administering to a mammal in need of such regeneration and/or maintenance an effective amount of a composition according to the invention.

The invention will now be elucidated by way of the following examples, without however being limited thereto.

Example 1: Synergistic effect

The anti-inflammatory effects of rosehip and ligustilide, hydroxytyrosol, magnolol, and genistein were evaluated in activated macrophages by determining the inhibition of the synthesis of nitric oxide and/or proinflammatory prostaglandins (PG). PGE 2 plays a critical role in the inflammation process, while nitric oxide (NO) is a hallmark of inflammation in various chronic inflammatory diseases including various forms of arthritis, gastro-intestinal diseases and metabolic syndrome.

Biologically standardized rosehip powder was obtained from Hyben Vital International, Langeland, Denmark, and dissolved in DMSO. Ligustilide and genistein was synthesized by DSM Nutritional Products. Hydroxytyrosol was from Cayman Chemicals or synthesized by DSM Nutritional Products. Magnolol was obtained from Apin Chemicals Ltd, UK. According to the suppliers' data sheet all products were >90% pure and obtained in powder form. They were dissolved in DMSO in concentrated form and did not contain byproducts that interfered with the assays. Final vehicle (DMSO) concentration did not exceed 0.2 % v/v in the assays.

The anti-inflammatory effects of compounds was tested in cellular assays using a murine macrophage indicator cell line, RAW267.7, which was purchased from American Type Culture Collection, (ATCC) and cultured in DMEM according to the protocol provided by ATCC. Cells (~50'000/well) were seeded into flat-bottomed microtiter plates and cultured for one day. Cells were then starved in complete medium containing 0.25% fetal calf serum (FCS) (D-025). After

overnight culture, medium was removed and replaced by 100 μL of D-025 containing the test compounds at twice the final concentration. Subsequently, 100 μL of D-025 containing 2 μg/ml lipopolysaccharide (LPS) was added (i.e. final LPS concentration of 1 μg/ml) and the cells were cultured for 24 hours. Substances were usually tested in a concentration range from 0.2 to 50 μM in two-fold dilution steps. In the case of rosehip extract, the concentration range was from 3 - 2000 μg/ml. Concentrations of nitrite which was generated from nitric oxide released by cells were determined by the Griess reaction (see e.g Imai et al. Biochem Biophys Res Comm, 197, 105 [1993]) using sodium nitrite as standard. Briefly, 50 μl of supernatant was mixed with Griess reagent 1 (25 μL) and Griess reagent 2 (25 μL), centrifuged and the optical density at 540 nm determined. PGE 2 secreted into the cell culture medium was determined by EIA obtained from Cayman Chemicals (Ann Harbor, WI, USA) and used according to the manufacturer's instructions. IC 50 values were calculated using a two-parametric least-square fitting equation [ y = A+((B-A) / (l+((C-x) λ D))] for best-fit curves (Excel fit software program).

In Table 1 it is shown that individually, all substances inhibited the production of inflammatory mediators (Table 1). This is indicated by IC 50 values, which vary between substances reflecting substance-specific biological potencies.

As shown in Table 2 rosehip inhibits nitric oxide production when combined with ligustilide, hydroxytyrosol (OH-tyrosol), magnolol or genistein. A positive value for δ (observed-additive) means that the two substances out-perform the inhibitory power of the two individual components of the mixture. With 'observed' is meant the actually measured inhibition. With 'additive' is meant the theoretical sum of the inhibition of the two compounds.

In Table 3, it is shown that rosehip when combined with magnolol synergistically inhibited PGE 2 production.
