摘要
对中药藤黄中的藤黄酸的提取分离进行了方法改进.通过渗漉、吡啶成盐、三次重结晶、置换萃取等步骤得到橙黄色藤黄酸单体.藤黄酸得率为23.9%.并通过IR、MS、1HNMR、13CNMR对藤黄酸进行了结构鉴定.
The studies were opitimized the extraction process of gambogic acid from traditional chinese medicine gamboge resin.Gambogic acid was isolated in overall yield of approximately 23.9% from the easily and widely available gamboge resin.It was purified by converting the Percoaltion extract from the gamboge resin into pyridine salt,and then three times recrystallization in methanol,followed by displacing with hydrochloric acid and extracting with ether.The structure of gambogic acid was confirmed by IR,1HNMR,13CNMR and MS.
