摘要
利用溶剂提取法从鱼腥草中提取鱼腥草素．研究了乙醇浓度、固液比、提取时间、提取温度等工艺条件对鱼腥草素提取率的影响,最佳提取工艺条件为:以50%乙醇溶液为溶剂,固液比1:30,温度50℃,时间65min,提取率可达11．0%．
Decanoyl acetaldehyde was extracted from houttuynia cordata thunb by the method of solvent extraction process. The extraction constant such as ethanol concentration, the ratio of solid and liquid, time, temperature affecting in extraction rate were studied and the results show that the most suitable process are as follows： 50% ethanol solution as solvent, the ratio of solid and liquid is 1：30, the temperature is 50℃ and the time is 65min, and the highest extraction rate is 11.0%.
