        摘  要   目的:建立同时测定参芪延肾颗粒中淫羊藿药材中朝藿定A1、朝藿定A、朝藿定B、朝藿定C、淫羊藿苷及宝藿苷Ⅰ 6个黄
        酮类成分含量的方法。方法:采用高效液相色谱(HPLC)法,色谱柱为Waters Symmetry C18,流动相为乙腈-水(梯度洗脱),流速为
        1.0 mL/min,柱温为25 ℃,检测波长为270 nm,进样量为10 μL。在外标法的基础上分别采用多点校正法及斜率校正法建立各成

        定 C、淫羊藿苷及宝藿苷Ⅰ检测质量浓度线性范围分别为 2.03~50.80、4.34~108.60、2.26~56.40、4.14~103.60、4.24~106.00、
        1.78~44.60 μg/mL(r 均为 0.999 5);检测限分别为 65.80、71.49、74.26、68.79、70.56、86.09 ng/mL;定量限分别为 196.62、213.63、
        223.72、208.46、215.96、255.88 ng/mL;精密度、稳定性(24 h)、重复性试验的 RSD<2%(n=6);平均回收率为 96.03%~99.04%
       (RSD 为 0.65%~1.04%,n=6);采用多点校正法,朝藿定 A1、朝藿定 A、朝藿定 B、朝藿定 C、宝藿苷Ⅰ的 fk/s分别为 0.837、0.818、
        0.845、0.831、1.387;采用斜率校正法,朝藿定 A1、朝藿定 A、朝藿定 B、朝藿定 C、宝藿苷Ⅰ的 fk/s分别为 0.835、0.815、0.851、0.829、
        1.419。采用一测多评两种校正法与外标法所得含量结果比较,无显著性差异(P>0.05)。结论:建立的HPLC-一测多评法结果准
        确,可应用于参芪延肾颗粒中淫羊藿药材中朝藿定A1、朝藿定A、朝藿定B、朝藿定C、淫羊藿苷及宝藿苷Ⅰ6个黄酮类成分的质量
        控制。

        ABSTRACT   OBJECTIVE:To establish a HPLC method for simultaneous determination of 6 flavonoids in Epimedium brevicornu
        from Shenqi yanshen granules,such as epimedin A1,epimedin A,epimedin B,epimedin C,icariin and baohuoside Ⅰ.
        METHODS:HPLC method was adopted. The determination was performed on Waters Symmetry C18 column with mobile phase
        consisted of acetonitrile-water(gradient elution)at the flow rate of 1.0 mL/min;the column temperature was 25 ℃,and detection
        wavelength was 270 nm. The sample size was 10 μ L. Relative correction factors(fk/s )of each component to icariin(reference
        substance)were established by multi-point correction method and slope correction method on the basis of external standard method
        to calculate the contents of each component. The contents of 6 flavonoids in 4 batches of Shenqi yanshen granules determined by
        HPLC external standard method were compared with by multi-point correction method and slope correction method. Feasibility and
        accuracy of quantitative analysis of multi-components by single-marker(QAMS)were validated. RESULTS:The linear range of
        epimedin A1,epimedin A,epimedin B,epimedin C,icariin and baohuoside Ⅰ were 2.03-50.80 μg/mL(r=0.999 5),4.34-108.60
        μg/mL(r=0.999 5),2.26-56.40 μg/mL(r=0.999 5),4.14-103.60 μg/mL(r=0.999 5),4.24-106.00 μg/mL(r=0.999 5),
        1.78-44.60 μ g/mL(r=0.999 5),respectively,the limits of detection were 65.80,71.49,74.26,68.79,70.56,86.09 ng/mL,
        respectively;the limits of quantification were 196.62,213.63,223.72,208.46,215.96,255.88 ng/mL,respectively;RSDs of
        precision, stability (24 h), reproducibility tests were less than 2% (n=6), respectively. The average recoveries were
                                                           96.03% -99.04% (RSDs were 0.65% -1.04% , n=6). By
