Roots and rhizomes of Veratrum patulum L. (Liliaceae), used as a source of the Chinese crude drug "Li-lu", have yielded two new steroidal alkaloids, 20-isoveratramine (1) and verapatuline (2), along with three known alkaloids, veratramine (3), veratrosine (4), and jervine (5). Structures of new alkaloids 1 and 2 were determined to be a C-20 epimer of 3 and N-(methoxycarbonyl)jervine, respectively, by the use of spectral data including 2D NMR.
作为中药“藜芦”来源的狭叶藜芦(藜芦科)的根及根茎,已分离得到两种新的甾体生物碱,20 -异藜芦胺(1)和藜芦帕图林(2),以及三种已知生物碱,藜芦胺(3)、藜芦宁(4)和介藜芦碱(5)。通过包括二维核磁共振在内的光谱数据确定,新生物碱1和2的结构分别为3的C - 20差向异构体和N -(甲氧基羰基)介藜芦碱。
