【摘要】 目的:优化三七总皂苷提取工艺。方法:在考察提取溶媒和粒径的前提下,采用正交试验法,以提取物中三七总皂苷含量为考察指标,对影响三七提取的因素进行了考察。结果:提取次数对三七总皂苷得率有显著影响。选择过8目筛的药材,用10倍量70%乙醇提取3次,每次1.5h,所得三七总皂苷为85.74±3.16mg/g生药。结论:该工艺简便易行,得率较高,适于大生产。更多还原

【Abstract】 Objective: To optimize the conditions for the extraction of panax notogingseng saponins (PNS). Methods: After selected extraction solvent and suitable particle, we employed orthogonal experimental design to examine the conditions for the extraction by determination of PNS. Results: Significant effect was observed only in extraction times. Conclusion: The optimum condition for extraction of PNS was to extract panax notogingseng (Burk.) F. H. Chen with 10 times 70% ethanol for 1.5 hours for 3 times.更多还原
