        摘  要   目的:建立同时测定黄芪经九州虫草双向固体发酵前后毛蕊异黄酮苷、芒柄花苷、毛蕊异黄酮、芒柄花素、黄芪皂苷Ⅳ、异
        黄芪皂苷Ⅱ、环黄芪醇、异黄芪皂苷Ⅰ等8种成分含量的方法,并探讨发酵处理对黄芪中上述8种成分含量的影响。方法:采用高
        效液相色谱-二极管阵列检测器-蒸发光检测器联用技术(HPLC-DAD-ELSD)进行含量测定。色谱柱为Agilent 5 TC-C18;流动相为
        0.1%甲酸水溶液(A)-乙腈(B),梯度洗脱;流速为1 mL/min;柱温为30 ℃;DAD检测波长为260 nm;ELSD蒸发管温度为100 ℃;
                                                                                                     2
        雾化器温度为 80 ℃;载气流速为 1.6 L/min;进样量为 15 μL。结果:8 种成分在各自质量浓度范围内线性关系良好(R 均大于
        0.999 0);精密度、稳定性、重复性试验的RSD均小于3%(n=3或n=6);平均加样回收率为97.88%~101.32%,RSD为1.22%~
        2.39%(n=6)。以未发酵黄芪中相应成分含量为100%计算,经九州虫草双向固体发酵后,黄芪中毛蕊异黄酮苷、芒柄花苷、毛蕊
        异黄酮、芒柄花素、黄芪皂苷Ⅳ、异黄芪皂苷Ⅱ、环黄芪醇、异黄芪皂苷Ⅰ的含量变化率分别为-98.51%、-96.41%、-94.74%、
        -96.40%、289.20%、20.25%、-75.05%、562.46%。结论:黄芪经过九州虫草发酵后,有利于增加其主要活性成分黄芪皂苷Ⅳ、异
        黄芪皂苷Ⅰ、异黄芪皂苷Ⅱ的含量。

        ABSTRACT    OBJECTIVE:To establish a method for simultaneous determination of calycosin glucoside,ononin,calycosin,
        formononetin,astragaloside Ⅳ,isoastragaloside Ⅱ,cycloastragenol and isoastragaloside Ⅰ in Astragalus membranaceus before
        and after bidirectional solid fermentation with Cordyceps kyushuensis,and to investigate the effects of fermentation on the contents
        of above 8 components in A. membranaceus. METHODS:HPLC-DAD-ELSD was adopted. The determination was performed on
        Agilent 5 TC-C18 column with mobile phase consisted of 0.1% formic acid aqueous solution-acetonitrile(gradient elution)at the
        flow rate of 1 mL/min. The column temperature was set at 30 ℃. DAD detection wavelength was set at 260 nm,ELSD evaporation
        tube temperature was 100 ℃,atomizer temperature was 80 ℃,carrier gas flow rate was 1.6 L/min;injection volume was 15 μL.
                                                                                                 2
        RESULTS:The eight components had a good linear relationship within their respective ranges of concentration(all R >0.999 0);
        RSDs of precision,stability and repeatability tests were all less than 3%(n=3 or n=6);the recoveries was 97.88%-101.32%,
        and RSDs were 1.22% -2.39% (n=6). Setting the content of components in unfermented A. membranaceus as 100% ,after
        bidirectional solid fermentation with C. kyushuensis,the change rates of 8 components were -98.51%,-96.41%,-94.74%,
        -96.40%,289.20%,20.25%,-75.05%,562.46%,respectively. CONCLUSIONS:After fermentation with C. kyushuensis,the
        contents of active components as astragaloside Ⅳ ,isoastragaloside Ⅰ and isoastragaloside Ⅱ can be increased significantly in
        A. membranaceus.
