【摘要】 从蒙自藜芦(Veratrum mentzeanum Loesn.f.)的须根中分离到11个化合物,其中6个鉴定为甾体生物碱,即:藜芦胺(veratramine)、藜芦胺N-氧化物(veratramine N-oxide)、藜芦明宁(veramiline)、3,15-二当归酰基计明碱(3,15-diangeloyl-ger-mine)、3-当归酰基计明碱(3-angeloyl-germine)、龙葵胺(solanidine);另外5个分别鉴定为β-谷甾醇、β-谷甾醇硬脂酸酯、胡萝卜甙、蜡酸及硬脂酸。其中藜芦胺N-氧化物和3-当归酰基计明碱系首次从植物中分离到。更多还原

【Abstract】 From the fibrous roots of Veratrum mentzeanum Loesn. f., with two new steroidal alkaloids, veratramine N-oxide ( 2 ) and 3 -angeloyl germine (5) were isolated. In another four known ateroidal alkaloids, veratramine (1), veramiline ( 3 ) , 3 , 15-diangeloyl germine ( 4 ) , solanidine ( 6 ) , and β -sito-sterol, β -sitosteryl stearitate, daucosterol, stearic acid and cerotic acid were isolated too.更多还原
