Objective To comprehensively evaluate the quality of Croci Stigma from different regions by using the entropy weighted TOPSIS,and to provide evidence for the quality evaluation and regions selection of Croci Stigma.Methods The contents of picrocrocin,crocin I,crocin II and crocin III were determined by HPLC wavelength switching method.The total content of four components,loss on drying,total ash,absorbance and extract were chosen as detection indexes for Croci Stigma,and the weight was calculated by entropy weight method,and the indexes were statistically analyzed by TOPSIS method.The quality of Croci Stigma was comprehensively evaluated.Results The analysis results of entropy weighted TOPSIS method showed that the mean values of relative closeness(Ci)values of Croci Stigma from Zhejiang,Tibet,Anhui,Jiangsu provinces and shanghai city were 0.654,0.396,0.426,0.326 and 0.341,respectively.Overall,the quality of Croci Stigma in Zhejiang province was the highest.Conclusion The established entropy weighted TOPSIS method is objective,comprehensive and effective,which can be used for the comprehensive quality evaluation of Croci Stigma.
