Description
Chondroitin Sulfate is a sulfated Glycosaminoglycan composed of a chain of alternating sugars (N-Acetylgalactosamine and Glucuronic acid). It is one of the main components of cartilage and mucosa layers, forming the connective tissue that holds muscles, nerves and blood vessels together. It is used as a dietary supplement to support cartilaginous tissues and combat various forms of arthritis in humans and animals.   Items Specifications Appearance White to off-white Powder Identification Infrared Absorption(USP197K) Sodium Reaction(USP191) Assay More than 90%(HPLC) Specific rotation -20°~-30°(USP781S) Loss on drying NMT 10%(USP731) Chloride NMT 0.5%(USP221) Sulfate NMT 0.24%(USP221) Heavy metals NMT 20PPM(methodⅡUSP231) Protein NMT 6.0%(USP31) PH(1%H2O solution) 5.5~7.5(USP791) Residue on ignition 20%~30%(dried base)(USP281) Clarity ＜0.35 420nm Organic volatile impurities Meets requirements(USP467) Electrophoretic purity NMT 2.0%(USP726) Total bacterial count NMT 1000cfu/g(USP2021) Molds & Yeasts NMT 100cfu/g(LBC001) Salmonella Negative(LBC010) Escherichia Coli Negative(LBC012) Conclusion Conforms to the standard of USP31   Product Features   Original raw materials: Bovine CartilagesTest Method: HPLC & CPCOur products got excellent scores on the test of HPLC Enzymatic.
