豆科合欢属灌木合欢(Albiziaanthelmintica(Brongn.))主产于非洲西南部,其根皮制剂用于驱虫,特别是驱绦虫已久远。作者将切细的合欢根皮用甲醇在室温渗漉,其渗漉液缩后转入水中,用正丁醇提取,有机相减压浓缩得粗品,用乙醚洗后,溶于甲醇,用凝胶TSK—HW40(70×2cm)柱分离,以甲醇 Albizia anthalmintica (Brongn.) is mainly produced in the southwest of Africa. Its root bark preparations are used to repel insects, especially for driving aphids. The authors cut Acacia root bark with methanol at room temperature, the percolation liquid was reduced and transferred into water, extracted with n-butanol, and the organic phase was concentrated under reduced pressure to obtain a crude product. After washing with ether, it was dissolved in methanol and coagulated. TSK-HW40 (70 x 2cm) column separation with methanol
