The problem of an ageing population is relevant for the whole world and for Russia in particular. The object of the research is cattle bone meal (CBM) proteoglycans. The methodology of the work included preparing a bone meal extract, a cluster silver solution, separating proteoglycans by electrophoresis, determining the uronic acids content in the investigated preparations by the carbazole method, defining the total polyanions content, chondroitinase activity. Then, high performance liquid chromatography for fractionating proteoglycans and MMT analysis were performed.
