摘 要 :从展毛短柄乌头(Aconitum brachypodum var.laxiflorum Fletcher et Lauener)根中分离鉴定了五个二萜生物碱,其中四个为已知成分,分别为乌头碱(aconitine)、3一去氧乌头碱(3-deoxyaconitine)、3-乙酰乌头碱(3-acetylaconitine)、雪乌碱(penduline),另一个为新成分,命名为丽鲁碱(laxiconitine),其结构通过光谱分析及化学反应测定如(1)。
Abstract:Four known alkaloids, aconitine, 3-deoxyaconitine, 3-acetylaco-nitine, penduline and a new alkaloid, named laxiconitine, C26H41NO8, have been isolated from the roots of Aconitum brachypodum var. laxiflorum Flet-cher et Lauener.The chemical structure of laxiconitine was established as (1 ) by IR, 1H NMR, 13C NMR spectral data and chemical reactions.
