The study of secondary metabolites Petasites japonicus (Siebold&Zucc.) Maxim, growing on Sakhalin island
Abstract
The natural habitat of the Japanese butterbur (Petasites japonicus) occupies the territory of Korea, North China, and Japan. In Russia it grows in the Kuril Islands and in the Sakhalin Island. Methods. Air-dry powdered herb Petasites japonicus was tested, harvested on the Sakhalin Island during the growing season of 2014. Raw materials were extracted with 70 % ethanol, and high-performance liquid chromatography (HPLC) was carried. Results. Polysaccharides were isolated from grass and roots of Petasites japonicus, the total polyphenol fraction was determined. Conclusions. Raw materials of Japanese butterbur growing on Sakhalin Island contain significant amount of polyphenols and polysaccharides. The main bodies of the accumulation of secondary metabolites are leaves and roots.
