Determination of multi-index components in Mongolian medicine Sanzi powder
Objective To conduct an overall quality evaluation of Mongolian medicine Sanzi powder based on multi-index component content determination combined with grey relational analysis(GRA)for order preference by similarity to ideal solution(TOPSIS)method.Methods The contents of chebulic acid,gallic acid,punicalin,punicalagin,jasminoside B,caffeic acid,corilagin,geniposide,chebulagic acid,1,2,3,4,6-O-pentagalloylglucose,chebulinic acid and ellagic acid were determined by HPLC,and the overall quality evaluation model was established by GRA combined with TOPSIS.Results Totally 12 indicator components showed a good linearity within their respective mass concentration ranges,with correlation coefficients r no less than 0.9995.The average recovery was 96.72%～104.07%,and the RSD was 1.4%～2.6%.The results of GRA and TOPSIS analysis were basically the same.According to the values from TOPSIS and GRA analysis,the sample S1,S3,S4,S6,S10,S12,S14,and S15 ranked the top 8 of all samples.Conclusion GRA-TOPSIS method eliminates the interference of human factors and transforms the mult-dimensional problem into one-dimension one,improves the science and accuracy of multi-index decision analysis,accurately reflects the gap between evaluation schemes,and the evaluates overall quality and screens high-quality resources of Sanzi powder.
