基于信息熵理论的中药提取工艺优选
摘要
目的:探讨信息熵在中药提取工艺评价中的应用。方法:以菝葜为模型药物
以总黄酮、白藜芦醇、落新妇苷和黄杞苷含量为评价指标
计算多指标的信息熵及权重系数
确定综合评价指标。结果:利用基于信息熵的数据处理方法处理正交试验数据
筛选出影响菝葜提取效果的因素
优选菝葜提取的最佳方案为加10
8倍量水分别提取2
1.5 h。结论:基于信息熵理论的数据处理方法可应用于中药提取工艺综合评价。
Abstract
Objective: To explore application of information entropy theory in evaluation of extraction technology for traditional Chinese medicine.Method:With Smilax china as a model drug
with the content of total flavonoids
resveratrol
astilbin and engeletin as indexes
comprehensive evaluation index was determined by calculating information entropy and weight coefficient of multi-indexes.Result:Orthogonal test data was handled by data processing method basing on information entropy
factors were selected which affected extraction effect of S.china
optimized optimum program of extraction technology for S.china was:added 10
8 times the amount of water to extract 2
1.5 h
respectively.Conclusion:Data processing method could be used in comprehensive evaluation of extraction technology for traditional Chinese medicine which basing on information entropy theory.
