Three new flavonol glycosides, isorhamnetin 3-(2"-acetyl) glucoside, limocitrin 7-glucoside, and limocitrin 3,7_diglucoside, were isolated from the aerial parts of Sedum acre. The known compounds quercetin, isorhamnetin and their 3- and 3,7-di-glucosides, isorhamnetin7-glucoside and limocitrin and its 3-glucoside were also identified. The structure of the compounds was determined by means of spectroscopic and chemical methods.
