DYNAMIC OF ACCUMULATION OF WATER-SOLUBLE POLYSACCHARIDES IN PETASITES JAPОNICUS (SIEBOLD&ZUCC.) MAXIM
Abstract
Polysaccharides are one of the most important classes of biopolymers, along with nucleic acids and proteins. Polysaccharide or carbohydrate biopolymers play a varied role in nature and in vivo, forming the bulk of the organic matter of the biosphere. For water-soluble polysaccharides characterized by a wide spectrum of biological activity: hepatoprotective, antihypoxia, sorption, immunomodulatory, hypolipidemic, anti-inflammatory, anti-tumor properties are revealed, proved their prebiotic effect.
One of the most promising species in terms of production of biologically active substances, in particular water-soluble polysaccharides is Petasites japonicus (Siebold & Zucc.) Maxim (Asteraceae), the plant is characterized by rapid growth and high biomass. In Japan, P. japonicus has long been actively used for food.
The results of the study of the dynamics of accumulation of water-soluble polysaccharides in various organs of Petasites japonicus (Siebold & Zucc.) Maxim, harvested in Kholmsk district, Sakhalin Island in the different phases of growth. It is shown that the raw material P. japonicus, which grows on the island. Sakhalin, contains significant amounts of water-soluble polysaccharides. It found that the major organs of accumulation of water-soluble polysaccharides are the roots and leaves. The maximum content of water-soluble polysaccharides in raw Petasites japonicus for the roots is in August (17,4%), leaf – May (5,4%), for the petiole – July (4,4%).
