| Abstract: | Objective] The research aimed to optimize the extracting procedure of caffeic acid and ethyl caffeate from Semen pharbtidis.Method] Organic solvent extraction was used.The extraction process was optimized by L16(44) orthogonal design with the extract yields of caffeic acid and ethyl caffeate as indices.Result] The optimal condition was:using 95% ethanol as solvent,ratio of solid to liquid 1∶20,extracting 4 h at 70 ℃.Conclusion] The extraction process is simple and convenient with excellent stability.There are high yields of caffeic acid and ethyl caffeate. |
