从垂盆花鲜叶中鉴定出两个新的黄酮苷：山奈酚3-0-beta-neohesperidoside-7-0-alpha-rhamnoside和栎素3-0-beta-neohesperidoside-7-0-alpha-rhamnoside。最大。此外，还鉴定了已知的化合物--栎素、山奈酚及其3-葡萄糖苷、7-鼠李糖苷和3，7-地鼠李苷。所有化合物都用化学和光谱方法进行了表征。通过NOE实验检测了苷元分子7-羟基处的糖苷键。
Two new flavonol glycosides, kaempferol 3-0-beta-neohesperidoside-7-0-alpha-rhamnoside and quercetin 3-0-beta-neohesperidoside-7-0-alpha-rhamnoside were identified in the fresh leaves of Sedum telephium ssp. maximum. The known compounds, quercetin, kaempferol and their 3-glucosides, 7-rhamnosides and 3,7-dirhamnosides were also identified. All compounds were characterized by means of chemical and spectroscopic methods. NOE experiments were performed to detect the glycosidic bond at the 7-hydroxyl of the aglycone molecules.
