METHOD OF OBTAINING COLLAGEN FROM BIOLOGICAL MATERIAL Russian patent published in 2014 - IPC A61K35/12 C07K14/78 C07K1/36 

FIELD: chemistry.

SUBSTANCE: invention represents a method of obtaining collagen from biological material, which includes milling of a raw material, liquid processing of the biological material with obtaining a collagen-containing substance, separated into a sediment and liquid fraction, characterised by the fact that as the biological material applied is a medusa, preferably Rhopilema, preferably its cupola, which is crushed preferably to 1-2 mm, and for obtaining the collagen-containing substance the material prepared in such a way is mixed with drinking water with a ratio by the raw material weight to water as 1:2 and extracted at a temperature preferably of 15-18°C for 6-12 hours with periodical mixing, after that, the obtained extract is separated into the liquid fraction and collagen-containing sediment, which is after that dehydrated to moisture weight in it not more than 10%, after which it is pre-packed and packed.

EFFECT: extension of an arsenal of methods for obtaining neutral collagen.
