摘要
目的:本实验主要对金丝桃素的纯化工艺进行研究。方法:用无水乙醇从贯叶连翘中提取金丝桃素,再用大孔吸附树脂分离金丝桃素,后分别采用明胶水溶液法、pH值法及明胶水溶液+pH值法分离纯化金丝桃素。结果:采用明胶水溶液+pH值法样品中金丝挑素含量最高,平均含量为1.42%。结论:该方法操作简单,成本低廉,金丝桃素收率高,便于规模化生产。
Objective：This experiment aims to investigate the purification process for hypericin from Hypericum perforatum L.. Methods： Hypericin was extracted from Hypericum perforatum L. by alcohol and separated by macroporous resin. Then hpericin was purified by gelatin aqueous solution, pH value method and gelatin aqueous solution ＋pH value method, respectively. Results： The contents of hypericin was 1.42%. Conclusion： This method has these characteristics of concise procedure, cheap cost, high yield and is easy to produce in future.
