Two new flavonol glycosides, kaempferol 3-0-beta-neohesperidoside-7-0-
alpha-rhamnoside and quercetin 3-0-beta-neohesperidoside-7-0-alpha-rha
mnoside were identified in the fresh leaves of Sedum telephium ssp. ma
ximum. The known compounds, quercetin, kaempferol and their 3-glucosid
es, 7-rhamnosides and 3,7-dirhamnosides were also identified. All comp
ounds were characterized by means of chemical and spectroscopic method
s. NOE experiments were performed to detect the glycosidic bond at the
7-hydroxyl of the aglycone molecules.
