摘要
目的 优选三七的最佳提取工艺。方法 :采用正交试验法 ,以提取液中三七总皂苷含量为考察指标 ,对影响三七提取工艺的因素进行了研究。结果 实验设计三因素中提取方式有显著影响。结论 三七的最佳提取工艺为 :用 75 %乙醇浸渍三七 2 4h后 ,以每公斤每分钟 1～ 3 m L速度渗漉 ,收集相当于三七
Object To optimize the conditions for the extraction of Panax notoginseng (Burk ) F H Chen Methods Conditions for the extraction were studied by orthogonal experimental design as guided by the content of total notoginseng saponin present in the extract Results Significant effect was observed in 3 different experimental conditions Conclusion The optimum condition for the extraction of P notoginseng was to soak the drug in 75% alcohol for 24 h and then percolate at a rate of 1~3 ml/min to collect an amount corresponding to about 10 times of the quantity of P notoginseng
