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 of Hibiscus tiliaceus leaves. Methods The compounds were isolated by silica gel column chromatography and Sephadex LH-20 column chromatography. The structures of the compounds were identified by physico-chemical data analysis and spectral analysis. Results Fourteen compounds were isolated from the 70% ethanol extract of the leaves of Hibiscus syriacus and identified as xylitol (1), β-sitosterol (2), vanillin (3), syriacusin A (4), hibiscolactone (7), melatonin C (7), fumaric acid (8), kaempferol (9), quercetin (10), daucosterol (11) (12), succinic acid (13), rutin (14). Conclusion Compounds 7, 9 and 10 were isolated from this genus for the first time. Compounds 3 ~ 5, 8 and 12 ~ 14 were isolated from this plant for the first time.
