Abstract: From the fibrous roots of Veratrum mentzeanum Loesn. f., with two new steroidal a1kaloids, 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- stero1, β-sitosteryl stearitate, daucosterol, stearic acid and cerotic acid were isolated too.

Key words: Yeratrum mentzeanum

摘要： 从蒙自黎芦(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:黎芦胺(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。其中黎芦胺N-氧化物和3-当归酰基计明碱系首次从植物中分离到。
