目的:对假奓包叶Discocleidion rufescens叶的化学成分进行研究。方法:采用硅胶、聚酰胺柱色谱进行分离纯化,根据理化性质和波谱分析鉴定化合物结构。结果:首次从假奓包叶的叶中分离了15个化合物,经鉴定分别为大黄酚(1),大黄素甲醚(2),蒲公英赛醇(3),β-谷甾醇(4),胡萝卜苷(5),东莨菪内酯(6),芹菜素(7),金合欢素-7-O-β-D-葡萄糖苷(8),芹菜素-7-O-β-D-葡萄糖苷(9),木犀草素(10),香叶木素-7-O-β-D-葡萄糖苷(11),木犀草素-7-O-β-D-葡萄糖苷(12),没食子酸(13),穗花杉双黄酮(14)和肌醇(15)。结论:化合物1,2,8,11,13,15是首次从该属植物中分离得到,蒽醌类化合物为首次从该属植物中分离得到。
Objective: To study the chemical constituents of leaves of Discocleidion rufescens. Methods: The compounds were isolated and purified by silica gel and polyamide column chromatography. The structures of the compounds were identified by physicochemical properties and spectral analysis. Results: Fifteen compounds were isolated from the leaves of pseudacapsa leaves for the first time and identified as chrysophanol (1), physcion (2), dandelion alcohol (3), β-sitosterol Scopolactone (6), apigenin (7), acacetin-7-O-β-D-glucoside (8), apigenin-7-O-β-D-glucose Glycosides (9), luteolin (10), geraniol -7-O-β-D-glucoside (11), luteolin-7-O-β-D-glucoside (12) (13), biflavone (14) and inositol (15). Conclusion: Compounds 1, 2, 8, 11, 13 and 15 were isolated from this genus for the first time. Anthraquinones were isolated from this genus for the first time.
