        ABSTRACT    OBJECTIVE:To evaluate the correlation between color difference values and active constituent contents of crude
        and processed Zingiber officinale. METHODS:HPLC method was adopted to determint the content of 6 active constituents. The
        color difference values of crude and processed Z. officinale [lightness(L ),red-green axis component(a ),yellow-blue axis

        component (b )] were determined by chromatic aberration meter. SPSS 24.0 software was adopted for the correlation analysis
        between color difference values and active constituent contents. RESULTS: The linear range of zingiberone, 6-gingerol,
        8-gingerol, 6-shogaol, diacetoxy-6-gingerol and 10-gingerol were 2.65-105.90, 10.15-406.00, 4.87-194.80, 5.28-211.20,
        6.14-245.70,7.02-280.80 μg/mL(r>0.999). The limits of quantification were 7.46,13.68,14.37,16.62,17.03,17.99 ng,and the
        limits of detection were 2.24,4.11,4.31,4.99,5.11,5.40 ng,respectively. RSDs of precision,stability,and repeatability tests were
        all lower than 3%. The average recovery rates were 101.34%,102.14%,101.22%;103.12%,103.74%,103.54%;103.06%,
