摘要:

为了寻找一种新的方法从喜树叶中提取喜树碱和羟基喜树碱,充分利用喜树资源,以喜树叶粉末作为提取原料,采用超声—微波辅助提取技术提取喜树叶中活性成分喜树碱和羟基喜树碱。采用响应面优化方法设计,分别考察微波时间、料液比、微波功率、表面活性剂的浓度4个因素对总提取率的影响,优化得到最佳提取工艺条件。研究结果表明:当微波时间为10.5 min、料液比为1∶60、微波功率为850 W、表面活性剂浓度为 8.5 g·L-1时总提取率达到最佳。最佳工艺下总提取率为0.056 4%。

Abstract:

In order to explore a new method to extract camptothecin and hydroxy-camptothecin from camptothecin leaves and make full use of camptothecin resources, the active ingredients of camptothecin and hydroxy-camptothecin from camptothecin leaves were extracted from camptothecin leaves powder as raw material. In this paper, the influence of microwave processing time, solid-liquid ratio, microwave power and the concentration of surfactant on the total extraction rate were investigated respectively, and the optimum extraction conditions were obtained. The results showed that the optimal extraction rate was achieved when the microwave processing time was 10 min 30 sec, the solid-liquid ratio was 1∶60, the microwave power was 850 W, and the concentration of surfactant was 8.5 g·L-1. The total extraction rate was 0.056 4% under the optimal process.

Key words: camptothecin, hydroxyl camptothecin, surfactant, ultrasound-microwave-assisted method
