作者研究了分布在埃塞俄比亚的毛风车子 Combretum molle(R.Br.ex G.Don)Engl & Diels 茎皮丙酮提取物及其成分的抗疟原虫和锥虫活性。粉碎的该植物茎皮依次用石油醚和二氯甲烷提取,以除去亲脂物质,随后用丙酮提取,得黄色粉末状物。丙酮提取物经多种层析法分离得到2个鞣质 punicalagin(1)和 CM- The authors studied the anti-Plasmodium and Trypanosomiasis activity of the acetone extracts and their components of the stem bark Combretum molle (R. Br.ex G. Don) Engl & Diels distributed in Ethiopia. The pulverized bark of the plant was sequentially extracted with petroleum ether and methylene chloride to remove lipophilic substances, followed by extraction with acetone to give a yellow powder. Acetone extract was separated by multiple chromatographic methods to obtain two tannins punicalagin(1) and CM-
