正交试验法优化女贞子提取工艺

以特女贞苷、齐墩果酸、熊果酸的提取转移率为指标，采用单因素考察及正交试验法优化女贞子的最佳提取工艺。结果表明，最佳提取工艺为8倍量60%乙醇，提取3次，每次3 h。特女贞苷、齐墩果酸、熊果酸转移率分别为75.42%、93.86%、99.83%。优化所得工艺提取效果良好，工艺简便，可用于工业化生产。

Optimization of the extraction process for Fructus Ligustri Lucidi using orthogonal experimental design

Based on the extraction and transfer rates of specnuezhenide,oleanolic acid,and ursolic acid as indicators,the best extraction process for Fructus Ligustri Lucidi was deduced and optimized using single-factor investigation and an orthogonal experimental design.Results revealed that the optimum extraction process involved the use of eight-fold 60% ethanol,3-fold extraction,and 3-hour duration per round of extraction.The transfer rates of specnuezhenide,oleanolic acid,and ursolic acid were 75.42%,93.86%,and 99.83% respectively.The optimized extraction process features desirable extraction effects and a simple procedure,which can be efficiently used for industrial production.
