        摘   要   目的 建立同时测定地稔药材中6种成分含量的方法,考察上述成分与抗氧化活性的相关性。方法 采用超高效液相色谱
        法进行测定,以牡荆素为内参物,采用一测多评(QAMS)法计算23批地稔药材中没食子酸、原儿茶酸、异牡荆素、芦丁、鞣花酸的
        含量,并与外标法测定结果进行比较。采用1,1-二苯基-2-三硝基苯肼(DPPH)自由基法、2,2′-联氮-二(3-乙基-苯并噻唑啉-6-磺
        酸)二铵盐(ABTS)法和铁离子还原/抗氧化能力(FRAP)法测定23批地稔药材的抗氧化活性,以灰色关联度分析和双变量相关性
        分析评价地稔中6种成分含量与抗氧化活性的相关性。结果 地稔中牡荆素的含量为0.021%~0.182%,没食子酸、原儿茶酸、异
        牡荆素、芦丁、鞣花酸的 QAMS 法含量测定结果分别为 0.008%~0.042%、0.003%~0.023%、0.071%~0.283%、0.013%~
        0.140%、0.006%~0.021%,与外标法测定结果比较的P均大于0.05。灰色关联度分析显示,6种成分含量与抗氧化活性的灰色关
        联系数为 0.727 6~0.866 9。双变量相关性分析显示,牡荆素、异牡荆素、芦丁含量与抗氧化活性呈显著正相关(P<0.05 或 P<
        0.01),没食子酸、原儿茶酸含量与抗氧化活性呈显著负相关(P<0.05),鞣花酸与抗氧化活性无显著相关性。结论 成功建立了同
        时测定地稔中6种成分含量的QAMS法;地稔中6种成分含量与抗氧化活性均有较高相关性。

        ABSTRACT    OBJECTIVE To establish a method for simultaneous determination of six components in Melastoma dodecandrum
        and investigate its correlation with antioxidant activity. METHODS Ultra high-performance liquid chromatography(UPLC)method
        was adopted. The contents of gallic acid,protocatechuic acid,isovitexin,rutin and ellagic acid in 23 batches of M. dodecandrum
        were determined by quantitative analysis of multi-components by single-marker (QAMS) method,using vitexin as the internal
        reference. Then 1,1-diphenyl-2-picrylhydrazyl(DPPH)free radical method,2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)
        diammonium salt (ABTS) method and ferric ion reduction/antioxidant power (FRAP) method were applied to determine the
        antioxidant activity of 23 batches of M. dodecandrum. Grey correlation analysis and bivariate correlation analysis were used to
        evaluate the correlation between six components and antioxidant activity. RESULTS The content of vitexin were 0.021%-0.182%.
        The contents of gallic acid,protocatechuic acid,isovitexin,rutin and ellagic acid by QAMS method were 0.008% -0.042% ,
        0.003%-0.023%,0.071%-0.283%,0.013%-0.140% and 0.006%-0.021%,respectively. Compared with the results of external
        standard method,P was greater than 0.05. Grey correlation analysis showed that the grey correlation coefficients between the
                                                            contents of six components and antioxidant activity was 0.727 6-
