Abstract

From the leaves of Thevetia peruviana four new flavonol glycosides, kaempferol 3-glucosyl(1 --> 4) [6"'-sinapoylglucosyl] (1 --> 2) galactoside and 3-[2""-sinapoylglucosyl](1 --> 4)[6"'-sinapoylglucosyl](1 --> 2)galactoside and kaempferol and quercetin 3-[6"'-sinapoylglucosyl](1 --> 2)galactoside were isolated, together with the known compounds, kaempferol and quercetin 3-glucosyl(1 --> 2)galactoside. The glycosides were characterized from FAB mass, 1H and 13C NMR and UV spectral data.

摘要

从黄花夹竹桃的叶子中分离出四种新的黄酮醇苷，即山奈酚3 - 葡萄糖基(1→4)6'' - 芥子酰葡萄糖基半乳糖苷、3 - 2'' - 芥子酰葡萄糖基 6'' - 芥子酰葡萄糖基半乳糖苷、山奈酚和槲皮素3 - 6'' - 芥子酰葡萄糖基半乳糖苷，以及已知化合物山奈酚和槲皮素3 - 葡萄糖基(1→2)半乳糖苷。通过快原子轰击质谱、1H和13C核磁共振以及紫外光谱数据对这些苷进行了表征。
