【摘要】 采用反复的硅胶柱色谱进行分离、纯化,根据理化性质和波谱数据进行结构鉴定。从番泻叶中分离鉴定了8个化合物:Tinnevellin glycoside(Ⅰ)、异鼠李素-3-O-β-龙胆二糖苷(Ⅱ)、芹菜素-6,8-二-C-葡萄糖苷(Ⅲ)、大黄素-8-O-β-D-吡喃葡萄糖苷(Ⅳ)、山柰酚(Ⅴ)、芦荟大黄素(Ⅵ)、D-3-O-甲基肌醇(Ⅶ)、蔗糖(Ⅷ)。结论:化合物Ⅲ、Ⅶ、Ⅷ为首次从该植物中分离得到。更多还原

【Abstract】 Objective: To study the chemical constituents from the leaves of Cassia angustifolia.Methods: Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column.Their structures were elucidated by chemical and spectral methods.Results: eight compounds were isolated from the leaves of Cassia angustifolia,and identified as tinnevellin glycoside(Ⅰ),isorhamnetin-3-O-β-gentiobioside(Ⅱ),apigenin-6,8-di-C-glycoside(Ⅲ),emodin-8O-β-D-glucopyranoside(Ⅳ),kaempferol(Ⅴ),aloe emodin(Ⅵ),D-3-O-methylinositol(Ⅶ),sucrose(Ⅷ).Conclusion:Compounds Ⅲ,Ⅶ and Ⅷ are isolated from the plant for the first time.更多还原
