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.
