Blue cohosh, Caulophyllum thalictroides (L.) Michx. (Berberidaceae), is used primarily to cure menstrual disturbances and to ease childbirth. Alkaloids and saponins are considered to be responsible for its pharmacological activity. A detailed phytochemical investigation of blue cohosh resulted in the isolation of 15 compounds belonging to the alkaloids and the triterpene saponins. The structures of two alkaloids, caulophyllumines A (1) and B (2) and a saponin, cauloside H (3) both previously unknown were determined by spectroscopic techniques, including by 1- and 2-D NMR as well as by chemical analysis.
蓝升麻，即北美升麻（Caulophyllum thalictroides (L.) Michx.，小檗科），主要用于治疗月经紊乱和缓解分娩。生物碱和皂苷被认为是其药理活性的原因。对蓝升麻进行了详细的植物化学研究，分离出了15种属于生物碱和三萜皂苷的化合物。两种生物碱，升麻明A（1）和B（2）以及一种皂苷，升麻苷H（3），其结构此前均未知，通过光谱技术确定，包括一维和二维核磁共振以及化学分析。
