Meat product additive: Fish collagen added to meat products is not only improving product quality (as taste, juiceness), also increasing protein content and having no peculiar odor. Medllenet's research shows that sausage's appearance, texture and taste are the best with 2% more collagen and around 20% more moisture. Dairy products and drinks: If added to all sorts of dairy products and drinks, it can not only increase protein content and nutritive value, but also provide with human essential protein and amino acid, protecting joint, recovering from fatigue quickly. Bread and pastry: Added to bread and pastry, it can reinforce the protein nutrition in them , improve their trophic structure and quality. (2) Application in functional food Inhibiting blood pressure's ascent: It is confirmed that the peptide inhibiting ACE converzyme exists in collagen, as ACE is the main substance elevating blood pressure in vein. The result experimenting on symptomatic hypertension rats shows that the phenomenon elevating blood pressure of the group ingested collagen is obviously inhibited. Protecting gastric mucous membrane and anti-ulcer: In digestive tract, gastric mucous membrane's injury could cause gastrorrhagia. It is making people's attention that Ejiao (donkeyhide glue) could reduce gastric mucous membrane's blood flow and promote the effects of blood circulation and blood clotting. A lot of experiments show that collagen has the effect of protecting gastric mucous membrane. The result shows that collagen's effect on protecting gastric mucous membrane is better compared with milk's . Promoting bone forming: Collagen makes great effect on diversiform living activities. Bone is constituted by 1/3 organic and 2/3 inorganic substances, 80%∼90% of which is collagen. The bony tissue is very important for maintaining bone structure's integrity and the speciality of bone biomechanics. Ingesting collagen could promote bone formation and enhance ossein structure to improve bone intensity and prevent osteoporosis; It also could be a metabolic accelerator to promote collagen's synthesis in organism and retarding living organic caducity and hypofunction with aging. It shows that the sample compounded with collagen, calcium and vitamine has the effect on strengthening bone intensity, enriching the blood and promoting wound healing. Artificial plasma: As purified, elimilated heat source, molecular controlled between 50000∼100000, the collagen could maintain osmotic pressure as blood needs, it is much closer to natural plasma.

Application (1) Molding moisture: Fish collagen can intensely absorb water in the air and form a hydration shell to mold moisture, as having lots of hydrophilic groups. (2) Whitening: Fish collagen may prevent tyrosine translating into melanin, elimilate free radicals in body, anti oxygenation, promote cell's metabolism, postpone cell's aging. So it can make human skin soft, inch in elasticity, and obviously whiten. (3) Removing wrinkles: Researches show that skins aging, the losing of its flexibility and brightness, wrinkles forming are caused by gradual reduction of hydroxyproline with aging. Because of containing plenty of hydroxyprolines, fish collage can provide raw materials for collagen's synthesis, obviously postponing skin senility and reducing wrinkles. (4) Removing blain: Greasy skin may secrete a great deal of grease leading to blain's growth. Fish collagen may directly penetrate cutis to supply moisture, increase skin's water retention degree several times, so grease secretion decreases by itself. It also provides amino acids for skin collagen's metabolism, makes cell having regeneration function, so it can achieve the effect of removing blain. (5) Removing shadows under eyes and pouch: Skin structure may be tightened and have no slit using collagen, because blood doesn't accumulate at slit leading to shadows and pouch's forming. The skin of eye region descending causes forming pouch.Using fish collagen may let it turn tight and achieve removing effect.

DESCRIPTION: Camptothecin is an alkaloid derived from the chinese tree Camptotheca acuminata Decne. Camptothecin and its derivatives are unique in their ability to inhibit DNA Topoisomerase I, by stabilizing a covalent reaction intermediate termed the cleavable complex which ultimately causes tumor cell death. In clinical it is widely believed that camptothecin analogs exhibited remarkable anti-tumour and anti-leukaemia activity. Topoisomerase is a basilic enzyme in the process of DNA replication, it is responsible for the winding / unwinding of the supercoiled DNA composing the chromosomes. If the chromosomes cannot be unwound, transcription of DNA message cannot occur and the protein cannot be synthesized, it ultimately causes cell death. Application of camptothecin in clinic is limited due to serious side effects and poor water-solubility. At present, some camptothecin analogs,either semi-synthetic or synthetic drug based on camptothecin, have been applied cancerous therapy such as topotecan and irinotecan while others have been obtained satisfying curative effects in clinic.Product Information:CAS Number: 7689-03-4Origin Camptotheca acuminataMolecular Formula: C20H16N2O4Molecular Weight: 348.36Appearance: Light Yellow Crystal Purity by HPLC: 98% min / 99% minSolubility: Clear Yellow Solution at 1Mg/Ml in DimethylsulfoxideTest Item Appearance, Loss on drying, Assay, Specific Rotation, Melting point, Heavy Metals, Microbiological.Packing: Nt.W:1kg/bagStorage: Store in a cool and dry area.

INDICATIONS:In traditional Chinese medicine, Burdock Root, in combination with other herbs, is used to treat sore throats, tonsillitis, colds, and even measles. It is eaten as a vegetable in Japan and elsewhere. Burdock is a mild laxative. It also aids in the elimination of uric acid. The herb contains polyacetylenes that have both anti-bacterial & anti-fungal properties. By improving the function of many organs of elimination (liver, kidneys, bowels), many health conditions can be improved. Burdock Root contains high amounts of inulin and mucilage. This may explain its soothing effects on the gastrointestinal tract. Bitter constituents in the root may also explain the traditional use of Burdock to improve digestion. The polyacetylene constituents have also been shown to have anti-microbial activity. Burdock Root (and the fruit) also have the ability to mildly lower blood sugar (hypoglycemic effect).
