FIELD: biotechnology.
SUBSTANCE: claimed method includes utilization of acetic acid as cartilage eluating solvent. According the second embodiment method includes additional filtration of solution containing crude proteoglycan to remove precipitate from said solution. Then filtered solution is centrifuged, ethanol saturated with sodium chloride is added to obtained supernatant, and supernatant is centrifuged to concentrate abovementioned crude proteoglycan in precipitate. According the third embodiment method additionally includes dissolution of said precipitate with acetic acid. Proteoglycan obtained by method of present invention may bi administered perorally.
EFFECT: simplified and environmentally friendly method for proteoglycan production.
