        ABSTRACT    OBJECTIVE:To study the correlation between the color of Moutan Cortex and the contents of effective components
        before and after carbonized,and to provide reference for identification and quality evaluation of Moutan Cortex and its charcoal
        piece decoction. METHODS:Using colorimeter determination of Moutan Cortex and Moutan Cortex charcoal decoction pieces

        in Moutan Cortex and Moutan Cortex charcoal decoction pieces. On this basis,the correlation between the content of effective
        components and the chromaticity space parameter of a color was studied by SPSS 21.0 software. RESULTS:There was no
        correlation between gallic acid content and the chromaticity space parameter of a color (P>0.05). There was an extremely
        significant negative correlation between 5-HMF content and L ,b ,E ab (P<0.01),and an extremely significant positive

        pieces,and there is a significant correlation between the color of Moutan Cortex before and after processing and the content of its
        active ingredients.
