Abstrakt
As a part of systematic phytochemical studies of the vegatative parts of the taxon Schisandra chinensis basic extract from the leasves was prepared and further processed with diethyl ether and n-butanol. Ethereal extract was chromatographed on silica gel, and (E)-cinnamic acid kaempferol and quercetin were obtained as the main components.
The compounds were found in this taxon for the first time. Both benzopyrane derivatives are most probably aglycones of flavonoid glycosides contained in n-butanol exctract.
The contained mixture of flavonoids is highly complex and individual components have not yet been separated in a preparative scale.
