Studies on the alkaloids of Anemarrhena asphodeloides

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,~(1)H-NMR,and ~(13)C-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.
