In this paper,a UV spectrophotometric method has been developed to simultaneously determine the contents of quercetin and esculetin in Viola yedoensis Makino.The multiple linear regression(MLR) and partial least squares(PLS) method were utilized to analyze the hybrid UV absorption spectra of quercetin and Esculetin.Using standard addition method for the recovery experiment and PLS for the analysis of the experiment data,the determined recovery rates of quercetin and Esculetin were 85%-95%,77… Expand
