摘 要:目的:研究超微粉碎的粉碎度、提取时间、乙醇体积分数、提取温度等因素对参须中人参总皂苷溶出的影响,并探讨不同因素之间的交互作用。方法:通过单因素试验探讨粉碎度、提取时间、乙醇体积分数、提取温度等因素对参须中人参总皂苷溶出率的影响,在单因素试验基础上,利用响应曲面法对影响人参总皂苷溶出率的3个主要因素即超微粉碎时间、提取时间和乙醇体积分数进行优化。结果:人参总皂苷的含量与所考察的3个因素之间关系符合二次模型。确定最佳溶出工艺参数为:参须超微粉碎时间为9 min,70%乙醇为溶剂,提取温度50℃,提取时间70 min。实验结果显示,此条件下人参总皂苷平均溶出率为94.81%,与模型预测值非常接近,说明该模型比较可靠。结论:该优化工艺溶出快速、高效、简单、稳定。Objective:To investigate the effects of superfine cornminution extraction technology of ginseng total saponins from Panax ginseng fibrous root, and to make sure the optimal extraction condition. Methods : Optimal condition of ginseng total saponins from Panax ginseng fibrous root was based on single factor experiment to study the effects of crushing degree, extraction time, alcohol concen- tration and extraction temperature on extraction rate. Response surface method was used to investigate three main factors such as superfine eomminution time, extraction time and alcohol concentration. Results:The relationship between content of ginseng total saponins in Panax ginseng fibrous root and three factors fitted second degree polynomial models. The optimal extraction condition was 9 rain of superfine eomminution time ,70% of alcohol ,50 ℃ of extraction temperature and 70 min of extraction time. Under the optimal condition, ginseng total saponins from Panax ginseng fibrous root was average 94. 81% , which was consistent with the predicted value. Conclusion : The optimization of technology is rapid, efficient, simple and stable.
