目的:研究霸王花的化学成分。方法:采用各种现代色谱技术进行分离纯化,根据化合物的理化性质和波谱数据进行结构鉴定。结果:从霸王花的95%乙醇提取物中分离并鉴定了13种黄酮醇及其苷类化合物,分别为:山柰酚(1)、槲皮素(2)、异鼠李素(3)、山柰酚3-O-α-L-阿拉伯糖苷(4)、山柰酚3-O-β-D-葡萄糖苷(5)、槲皮素3-O-β-D-葡萄糖苷(6)、异鼠李素3-O-β-D-葡萄糖苷(7)、山柰酚3-O-β-D-半乳糖苷(8)、槲皮素3-O-β-D-半乳糖苷(9)、山柰酚3-O-β-D-芸香糖苷(10)、异鼠李素3-O-β-D-芸香糖苷(11)、山柰酚3-O-α-L-鼠李糖-(1→6)-β-D-半乳糖苷(12)和异鼠李素3-O-α-L-鼠李糖-(1→6)-β-D-半乳糖苷(13)。结论:以上化合物均为首次从该植物中分离得到。
Objective: To study the chemical composition of King Flower. Methods: All kinds of modern chromatographic techniques were used for the isolation and purification. The structures were elucidated on the basis of physicochemical properties and spectral data of the compounds. Results: Thirteen flavonols and their glycosides were isolated from 95% ethanol extract of King Flower and identified as kaempferol (1), quercetin (2), isorhamnetin (3) , Kaempferol 3-O-α-L-arabinoside (4), kaempferol 3-O-β-D-glucoside (5) ), Isorhamnetin 3-O-β-D-glucoside (7), kaempferol 3-O-β-D-galactoside (8) 3-O-β-D-rutinoside (10), isorhamnetin-3-O-β-D-rutinoside (11), kaempferol 3- L-rhamnose- (1 → 6) -β-D-galactoside (12) and isorhamnetin-3-O-α-L-rhamnose- (1 → 6) -β-D- Lactoside (13). Conclusion: The above compounds were isolated from this plant for the first time.
