摘要(Abstract):
目的通过R语言与正交试验分析,优化黄芪中有效成分黄芪多糖的提取工艺。方法采用水提醇沉法,以黄芪多糖提取量为指标,采用四因素(乙醇浓度、提取时间、提取次数及液料比)三水平正交试验设计法分组提取。通过经典正交分析法、R语言结合BP神经网络及遗传算法进一步目标寻优法优化黄芪多糖提取工艺,将两种优化工艺进行对比验证,得到黄芪多糖的最佳提取工艺。结果正交分析法得到黄芪多糖的优化提取工艺为:乙醇浓度75%,提取2 h,提取次数3次,液料比40∶1,此条件下黄芪中黄芪多糖的平均提取量为14.03 mg/g。R语言得到的优化提取工艺为:乙醇浓度95%,提取3 h,提取1次,液料比20∶1,此条件下黄芪中黄芪多糖提取量为18.68 mg/g。最佳工艺验证得出,正交分析优化法RSD为2.27%,R语言处理优化法RSD为1.51%,与预测结果相对误差仅有0.631%。结论 R语言环境下,BP神经网络模型与遗传算法的结合对实验结果具有良好的预测性,为中药材提取及相关制剂工艺优化提供了一种经济高效的优化方法。
