Perspective natural sources of chondroprotectors

The research objects in the work were natural sources of chondroprotectors. The research purpose was to study perspective natural sources of substances with chondroprotective properties. Such natural chondroprotectors as nutraceutical products made from green tea are studied in the work. Turmeric and ginger have been used since ancient times to treat osteoarthrosis. It has been established that collagen is a part of combined chondroprotectors. The mass fraction of structural protein in various tissues and organs of a living organism varies to a large extent. In pig skin the mass fraction of structural protein reaches 64%, in human skin the content of collagen is 8% higher, in cattle skin 80%, in marine mammals more than 80%; a significant amount of collagen is found in the skin of fish. In the connective tissue of whale fat, up to 88% of collagen is contained, in whale fins up to 83%. The percentage of collagen-containing raw fish is as follows: skin up to 12.6% (of the total weight of the fish); fins up to 8%, air bladder up to 11.4%, scales to 6%, bones up to 19%, sturgeon chord up to 10.2%. Glucosamine, extracted from mollusk shells, chondroitin from shark and bovine cartilage, and collagen hydrolysates are widely used since they are the main components of cartilage matrix. The novelty of this work lies in the systematization of scientific data on perspective natural sources of substances with chondroprotective and combined properties.
