【摘要】 目的:研究知母中的生物碱成分。方法:Sephadex LH-20,Rp-18及硅胶色谱柱分离纯化,根据理化性质和光谱数据鉴定结构。结果:分离鉴定了6个生物碱,分别为aurantiam ide acetate(1)、环(酪-亮)二肽(2)、香豆酰基酪胺(3)、N-反式阿魏酰基酪胺(4)、N-顺式阿魏酰基酪胺(5)、烟酸(6)。结论:化合物1~5为首次从百合科植物中分离得到,化合物1~6为首次从知母中分离得到。更多还原

【Abstract】 Objective: To investigate the alkaloids of Anemarrhena asphodeloides.Method: The compounds were isolated and purified by Sephadex LH-20,Rp-18 and silica gel column chromatography.Their chemical structures were elucidated on the basis of physicochemical properties and spectral data(IR,FAB-MS,¹H-NMR,and ¹³C-NMR).Result: Six compounds were isolated and identified as: aurantiamide acetate（1）,cyclo（Tyr-Leu）（2）,N-p-coumaroyltyramine（3）, N-trans-feruloyltyramine（4）,N-cis-feruloyltyramine（5）,and nicotinic acid（6）,respectively.Conclusion: For the first time,compounds 1-5 were separated from Liliacae plant,and compounds 1-6 were obtained from this plant.更多还原
