COMPARATIVE STUDY OF THE POLYSACCHARIDE COMPOSITION OF THE FRUITS LYCIUM BARBARUM L. AND LYCIUM LUTHENICUM MURR
The polysaccharide complex (PSCs) of the Lycium barbarum fruits (commercially available and introduced in the research Institute of Biotechnology of Gorsky GAU, RSO-Alania) and wild Lycium ruthenicum (Absheron District, Tugchay River valley) was studied for the first time. The PSC yield from Lycium barbarum L. fruits was 1. and 1.7 % versus 3.1% from Lycium ruthenicum . In the majority of cases, uronic acids are present in the fraction of water-soluble polysaccharides (WSPS-2) and pectin substances (PS) of Lycium ruthenicum in the amount of 60.0% and 58.0%, respectively. Arabinose is present in the largest amount in all PSK (more than 43%). The second largest monomer is galactose, which is also identified in all polysaccharides. The molecular weight of the 'acidic' and 'neutral' polysaccharides (WSPS-1 and WSPS-2) of the Lycium fruits under consideration differs to a significant extent.
