摘要: 钩吻素子(Koumine)是钧吻生物碱(Kou-Wen Alkaloids)中的单体之一,其分子式为C20H22N2O。它的晶体属单斜晶系,空间群为P21,晶胞参数为:α=8.422(0),b=13.209(1),c=7.881(1)Å,β=108.201(9)°,V=834.995Å3;Z=2;Dc=1.29g/cm3。 本文报道的钩吻素子是1981年Khuong-Huu F等人报导的钩吻素子的一个立体异构体,它们是钩吻素子的两个非对映体旋光异构体。

关键词: 钩吻素子, 旋光异构体, 非对映体

Abstract: Koumine, C20H22N2O, is the principal alkaloid of Kou-Wen alkaloids, Crystals ofkoumine belong to the monoclinic system with the space group P21, and the crystallographicdata are:a= 8.422(0), b= 13.209(1), c = 7.881(1)A,β = 108.201(9), V= 834.9953Å, Z = 2;Dc = 1.29g/cm3. The result shows that the koumine here determined is a stereo-isomer of that reportedby Khuong-huu F et al in 1981. They are two non-enantiotopic optical isomers of koumine.

Key words: Koumine, non enantiomer, optical isomer, crystal structure
