摘 要:目的:对龙胆科Gentianaceae獐牙菜属植物大籽獐牙菜Swertia macrosperma的干燥全草进行化学成分研究。方法:大籽獐牙菜的干燥全草用水提取,依次用石油醚、乙酸乙酯、正丁醇萃取,对乙酸乙酯萃取部分采用各种柱色谱进行分离纯化,通过波谱数据分析(1H-NMR,13C-NMR,MS)进行结构鉴定。结果:从乙酸乙酯萃取部分分离鉴定了13个化合物,其中5个酮及其苷,2个裂环烯醚萜苷,以及6个其他类化合物。分别鉴定为norbellidifolin(1),1-羟基-3,7,8-三甲氧基酮(1-hydroxy-3,7,8-trimethoxyxanthone,2),norswertianolin(3),swertianolin(4),1,3,7,8-四羟基酮-1-O-β-D葡萄糖苷(1,3,7,8-tetrahydroxyxanthone-1-O-β-D-glucopyranoside,5),獐牙菜苦苷(swertiamarin,6),decentapicrin(7),松柏醛(coniferl aldehyde,8),芥子醛(sinapaldehyde,9),balanophonin,(10),β-谷甾醇(β-sitosterol,11),胡萝卜苷(daucosterol,12),齐墩果酸(olean-olic acid,13)。结论:其中化合物2,4~10为首次从大籽獐牙菜中分离得到。Objective: To study the chemical constituents of Swertia macrosperma.Method: The air-dried whole plants of Swertia macrosperma were extracted with boiling water.The extract was concentrated to a small amount of volume and extracted with petroleum ether,EtOAc and n-BuOH,successively.The compounds were isolated and purified by column chromatography from the EtOAc fraction,and identified based on spectral analyses(MS,1H-NMR,13C-NMR).Result: Thirteen compounds were isolated from S.macrosperma,and were characterized as norbellidifolin(1),1-hydroxy-3,7,8-trimethoxy-xanthone(2),norswertianolin(3),swertianolin(4),1,3,7,8-tetrahydroxyxanthone-8-O-β-D-glucopyranoside(5),swertiamatin(6),decentapicrin(7),coniferl aldehyde(8),sinapaldehyde(9),balanophonin(10),together with β-sitosterol,daucosterol,and oleanolic acid.Cloclusion: Compounds 2,4-10 were obtained from Swertia macrosperma for the first time.
