摘要
目的:对广金钱草Desmodium styracifolium(Osbeck)Merr.的化学成分进行研究。方法:运用多种层析分离方法进行分离纯化,通过^1H、^13CNMR等波谱技术确定化合物的结构。结果:分离并鉴定了9个化合物分别为:芹菜素-6-C-葡萄糖-8-C-阿拉伯苷(1)、木犀草素-6-C-葡萄糖苷(2)、芹菜素-6-C-葡萄糖-8-C-木糖苷(3)、芹菜素-6-C-葡萄糖-8-C-葡萄糖苷(4)、芹菜素(5)、木犀草素(6)、豆甾醇-3—0-β—D-葡萄糖苷(7)、β-胡萝卜苷(8)、β-谷甾醇(9)。结论:其中化合物4~8均为首次从该植物中分离得到。
Objective : To investigate the ehemieal eonstituents from Desmodium styracifolium (Osbeek) Merr.. Methods : Column ehromatographic teehniques were used for isolation and purifieation of ehemical constituents of the plant and the structures were elueida-ted bv spectroscopic analysis. Results: Nine compounds were isolated and identified as:6-C-glyeop) ranosyl-8-C-arabinosyl apigenin ( 1 ), 6-C-glycopyranosyl luteolin ( 2 ), 6-C-glycopyranosyl-8-C-xyloeyl apigenin ( 3 ), 6-C-glycopyranosyl-8-C-glycopyranosyl, apigenin (4) , apigenin( 5 ) , luteolin ( 6 ) , stigmasterol-3-O-β-D-glucopyranoside ( 7 ) , β-dauosterol ( 8 ) and β-sitosterol ( 9 ). Conclusion: Compounds 4 - 8 are isolated from this plant for the first time.
