前文我们报告了自马钱科(Loganiaceae)植物胡蔓藤(Gelsmium elegans Banth.)根的生物碱提取物,分离得到了七个生物碱,其中一个新的氧化吲哚生物碱命名为胡蔓藤碱丙(humantendine),该化合物为无色透明的胶状物,[α]_D~(18)—123°(c 0.107乙醇),其氢溴酸盐为羌色方块状结晶,mp 158～162℃。根据元素分析和质谱给出的分子量(M~+342)确定其分 In the previous report, we reported on the alkaloid extracts from the roots of the genus Gelsmium elegans Banth. of the Loganiaceae plant. Seven alkaloids were isolated, one of which was named humantendine. The compound was a colorless, transparent gum [[alpha]]_D~(18)-123[deg.] (c 0.107 ethanol). Its hydrobromide salt was a rhodium-colored cube-like crystal, mp 158-162[deg.]C. According to elemental analysis and mass spectrum given molecular weight (M~+342) to determine its score
