摘要
目的研究绵枣儿Scillascilloides全草的化学成分。方法利用硅胶柱色谱及制备液相等技术进行分离纯化,并利用波谱技术鉴定其结构。结果从绵枣儿全草95%乙醇提取物中分离得到18个化合物,分别鉴定为绵枣儿素(1)、2-羟基-7-0-甲基绵枣儿素(2)、4'-demethyleucomin(3)、5-羟基-7-甲氧基-3-(4-羟基苯亚甲基1色原-4-酮(4)、4'-demethyl-3,9-dihydroeucomin(5)、3'-hydroxy-3,9-dihydroeucomin(6)、8-O-demethyl-7-0-methyl-3,9-dihydropunctatin(7)、芹菜素(8)、木犀草索(9)、金圣草黄素(10)、3-脱氢.15.脱氧尤可甾醇(11)、15-脱氧尤可甾醇(12)、4-烯丙基儿茶酚(13)、norlichexanthone(14)、drimiopsinC(15)、6-阿魏酰梓醇(16)、梓苷(17)、黄金树苷(18)。结论首次从绵枣儿属中分离得到环烯醚萜类化合物(16-18):化合物4、7-10和化合物13-18为首次从该属植物中分离得到。
Objective To study the chemical constituents from Scilla scilloides. Methods The chemical constituents were isolated and purified by column chromatography and their structures were identified by spectral data. Results Eighteen compounds were isolated from S. scilloides. Their structures were identified as scillascillin (1), 2-hydroxy-7-O-methylscillascillin (2), 4'-demethyleucomin (3), 5-hydroxy-7-methoxy-3-(4-hydroxybenzylidene) chroman-4-one (4), 4'-demethyl-3, 9-dihydroeucomin (5), 3'-hydroxy-3, 9-dihydroeucomin (6), 8-O-demethyl-7-O-methyl-3, 9-dihydropunctatin (7), apigenin (8), luteolin (9), chrysoeriol (10), 3-dehydro-15-deoxoeucosterol (11), 15-deoxoeucosterol (12), 4-allylpyroeatechol (13), norliehexanthone (14), drimiopsin C (15), 6-feruloyleatalpol (16), eatalposide (17), and specioside (18). Conclusion Iridoids (16-18) are isolated from the genus Scilla L. for the first time. Compounds 4, 7-10, and 13-18 are isolated from the plants of this genus for the first time.
