        子可明显区分。结论:北五味子中五味子醇甲含量较高,南五味子中五味子酯甲含量较高,且南五味子中未检出五味子醇甲、五味
        子醇乙和五味子乙素。南、北五味子的三色空间值存在差异,即北五味子亮度小,颜色偏黑,南五味子颜色偏红、偏黄。南、北五味
        子有效成分含量与三色空间值具有相关性,即药材颜色越暗、红色程度越弱,五味子醇甲、五味子醇乙、五味子乙素、五味子丙素的
        含量越高;药材表面颜色越亮、红色程度越高,五味子甲素、五味子酯甲的含量越高;所建含量测定方法精密度高、稳定性好,可用
        于测定南、北五味子的含量;所建颜色定性识别模型可用于南、北五味子的鉴别。

        ABSTRACT    OBJECTIVE:To investigate the internal mechanism of Schisandra sphenanthera and Schisandra chinensis in
        determining quality by color(“color discrimination grading”)of medicinal materials,and to construct a qualitative identification
        model based on color quantization value. METHODS:HPLC method was used to determine the contents of 6 active components
        from 39 batches of samples. The colorimeter was used to determine 3-color spatial value [lightness value(ΔL ),red-green value
                                                                                            *
       (Δa ),yellow-blue value(Δb )]. SPSS 24.0 statistical software was used to analyze the correlation between the contents of 6
           *
                                 *
        active components and 3-color spatial values. Principal component analysis(PCA)was performed by using SIMCA-P14.1 software.
        RESULTS:The linear range of schizandrol A,schizandrol B,schisandrin A,schisandrin B,schisandrin C,schisantherin A were
        0.204 8-2.560 0,0.049 3-0.616 3,0.098 4- 1.230 0,0.046 3-0.578 8,0.010 6-0.132 0,0.100 0-1.500 0 μg(r>0.999 0);RSDs
        of precision,stability(12 h)and repeatability tests were all less than 3%. The recoveries were 98.14%-101.53%(RSD=1.08%,
        n=6),97.16%-101.05%(RSD=1.54%,n=6),98.29%-101.41%(RSD=1.29%,n=6),97.17%-100.36%(RSD=1.20%,n=
        6),97.32% -102.43%(RSD=1.77% ,n=6)and 98.02% -100.40%(RSD=0.84% ,n=6),respectively. Among 39 batches of
