摘要:对比研究了多溶剂萃取法与单溶剂萃取法精制印楝素的效果,并通过正交试验法选择了多溶剂萃取法精制印楝素的最佳试验条件为:萃取溶剂V(二氯甲烷)∶V(乙酸乙酯)1∶5,分相液V(丙酮)∶V(水)1∶1,V(萃取溶剂)∶V(分相液)10∶3,该方法可将乙醇提取物中印楝素的质量分数从3.68%提高到17.76%。多溶剂萃取法是一种简单高效的精制印楝素的方法。
Methods of enrichment of azadirachtin by solvent and multi-solvent partition were studied, The optimized condition of mulli-solvent partition of azadirachtin obtained by orthogonal tests was: solvent: dichloromethane: ethyl acetate( 1:5, V: V), separatory liquid: acetone: water (1:1 ), solvent: separatory liquid (10:3). Multi-solvent partition was found to be able to enhance the conten! of azadirachtin in ethanol extract from 3.68 % - 17.76 %. It is a simple and efficient method to enrich azadirachtin in its extracts.
