Four flavonol glycosides from Achlys triphylla.
Four new flavonol glycosides were isolated from the underground parts of Achlys triphylla in addition to eight known compounds. By means of spectroscopic analysis, the structures were characterized as isorhamnetin 3-glucosyl(1----3)galactoside, isorhamnetin 3-[6''acetylglucosyl(1----3)galactoside], isorhamnetin 3-[4''6''-di-acetylglucosyl(1----3)galactoside], and syringetin 3-[6''-acetylglucosyl(1----3)galactoside], respectively. In the aerial parts of the plant, seven known compounds were also confirmed.
