摘要: 利用响应面法同步优化藏药材白花龙胆花中龙胆苦苷和异荭草苷的提取工艺。单因素试验筛选出乙醇浓度、超声时间、超声温度三个主要因素,以龙胆苦苷和异荭草苷的得率(Y1Y2)为响应值,利用响应面法对白花龙胆花中龙胆苦苷和异荭草苷提取工艺进行优化。采用响应面法绘制三维及等高线叠加图,应用同步优化程序,得两种苷类物质均为高的最佳提取工艺参数为:乙醇浓度为62%,超声时间为65 min,超声温度为50 ℃,在此最佳条件下实际测得龙胆苦苷含量为 0.75%,异荭草苷含量为0.56%接近于模型预测值0.76%与0.55%;结果表明,响应面法优化得到的工艺条件参数准确、可靠,具有实用价值。

Abstract:

The ultrasound-assisted extraction process parameters of two active components (gentiopicroside,homoorientin) in Tibetan medicine Gentiana algida flower.To obtain the maximum of extraction ratio of the components.Three main factors including ethanol concentration,extraction time,extraction temperature were selected on the basis of experimental results of single factors.The optimum extraction condition were as follow:62% ethanol,extraction time 65 min,and extraction temperature 50 ℃.Under the conditions,the optimum extraction ratio of the two active components from G. algida flower was 0.75%,56%,close to the model prediction values (0.76% and 0.55%).The results showed that the parameters were accurate,reliable and practical.
