摘要
采用稀醇提取、树脂吸附和溶剂萃取的组合新工艺 ,将萜内酯含量从仅千分之几的银杏叶中富集到纯度 70 %以上 ,萜内酯回收率达 6 8%。
A simple preparative method for enrichment of terpenelactone from G.biloba leaves was developed. As starting material, G.biloba leave containing 0.4% terpenelactone was used. A final product containing over 70% terpenelactones was obtained by extraction with organic solvent and adsorption with resins, total revival yield of terpenelactones was 68%.
