摘要
目的研究黄槿Hibiscus tiliaceus枝叶的化学成分。方法采用硅胶柱色谱、Sephadex LH-20柱色谱分离化合物,并通过理化数据测定和波谱技术分析鉴定化合物的结构。结果从黄槿枝叶70%乙醇提取物中分离得到14个化合物,分别鉴定为木栓酮(1)、β-谷甾醇(2)、香草醛(3)、syriacusin A(4)、hibiscolactone(5)、莨菪亭(6)、臭矢菜素C(7)、反式丁烯二酸(8)、山柰酚(9)、槲皮素(10)、胡萝卜苷(11)、壬二酸(12)、丁二酸(13)、芦丁(14)。结论化合物7、9、10为首次从该属植物中分离得到,化合物3~5、8、12~14为首次从该植物中分离得到。
Objective To study the chemical constituents from the twigs and leaves of Hibiscus tiliaceus(Li medicine).Methods Compounds were isolated by repeated chromatography on silica gel and alumina gel column.Their structures were elucidated by chemical and spectroscopic methods.Results Fourteen compounds were isolated and identified as friedelin(1),β-sitosterol(2),vanillin(3),syriacusin A(4),hibiscolactone(5),scopoletin(6),cleomiscosin C(7),fumaric acid(8),kaempferol(9),quercetin(10),daucosterol(11),azelaic acid(12),succinic acid(13),and rutin(14).Conclusion This is the first report on the isolation of compounds 7,9,and 10 from the plants of Hibiscus Linn.,and compounds 3—5,8,and 12—14 from this plant.
