从藤本植物百解藤(Cyclea polypetata)全株的乙醇提取物分离得到七个生物碱,根据理化性质和波谱特征,被鉴定为碱Ⅰ(Cycleanine)、碱Ⅱ(d-Tetrandrine)、减Ⅲ(Berbamine)、碱Ⅳ(d-lsochondodendrine)、碱Ⅴ(L-curine)、碱Ⅵ(Cycleanoline)和碱Ⅶ(Mag-nofloring).其中以L-curine为主碱,含量达0.8%,它是合成外科手术用药肌松剂氯甲左旋箭毒碱的原料.这一发现与前人报导颇有出入.这对开发利用我国新的箭毒植物资源具有重要意义. Seven alkaloids were isolated from the ethanol extract of the whole plant of Cyclea polypetata, which were identified as Cycleanine, d-Tetrandrine, Berbamine, d-lsochondodendrine, L-curine, Cycleanoline and Mag-nofloring, of which L-curine is the main base with a content of 0.8% Surgical use of muscle relaxants Arodorpiment raw material, which is quite different from previous reports, which is of great significance for the development and utilization of new plant resources in China.
