Abstract:
This study was undertaken in order to determine the content of phenolic compounds (total polyphenols, tannins and catechins) in S. sieboldii herb and tubers. HPLC method was employed to determine the content of catechins. Using spectrophotometric method the content of tannins and total polyphenols was analyzed. The major component of catechins in the herb was epigallocatechin – 1.37 % in the herb; in subterranean organs the predominant components were catechin and epigallocatechin (0.18% and 0.19% respectively). Content of tannins in S. sieboldii herb was (1.67± 0.01) %; in tubers- (1.35± 0.05)%. Amount of total polyphenols expressed as pyrogallol showed that in S. sieboldii herb their content was (7.93±0.01) % and in subterranean organs − (11.08±0.05) %.
