摘　　要：从白线薯(Stephania brachyandra Diels)的块根中分得四种生物碱,经UV,IR,~1H-NMR,^(13)C-NMR,MS等方法鉴定为:清风藤碱(Sino-acutine,Ⅰ),克斑宁(Crebanine,Ⅱ),荷包牡丹碱(Dicentrine,Ⅲ),千金藤碱(Stephanine,Ⅳ)。其中,清风藤碱和克斑宁系首次从该植物中获得,收率分别高达1.02％和1.39％。清风藤碱的碘甲烷衍生物有一定的松弛横纹肌作用。Four alkaloids were isolated from the root tubers of Stephania brachy- andra growing wild in Xishuangbanna, Yunnan, China. They were identi- fied as sinoacutine (Ⅰ), crebaning (Ⅱ), dicentrine (Ⅲ), and stepha- nine (Ⅳ) by means of UV, IR, ~1H-NMR, ^(13)C-NMR, and MS spectral analysis. The main chemical crebanine (1.39％).
