Study on Process for Extraction of Rhodobryum giganteum
摘要
目的:采用正交设计法
对回心草的提取工艺进行优化。方法:采用L9(34)正交试验
乙醇体积分数(A)、乙醇用量(B)、提取时间(C)作为3个因素
每个因素选择3个水平
以熊果酸转移率来确定最佳工艺条件。结果:B
A影响最大
C最小。结论:最佳提取条件是A1B3C2
即60%乙醇16倍量提取2次
每次2 h。
Abstract
Objective: To study the parameters of extraction of Rhodobryum giganteum by orthogonal design.Method: With L9(34) orthogonal experiment
the ethanol concentration(A)
alcohol consumption(B)
extraction time(C) as three factors
each select three levels to determine the optimum process conditions by the transfer rate of ursolic acid.Result: B and A were the main factors to effect the extraction.Conclusion: The optimal extraction was as follows: 60% of ethanol concentration
