RP-HPLC测定苗药黑白保肝清颗粒中槲皮素的含量
摘要
目的:建立苗药黑白保肝清颗粒中槲皮素总量的测定方法。方法:采用RP-HPLC法
Diamonsil(TM)钻石C18柱(4.6 mm×250 mm
5μm)
以甲醇-0.2%磷酸(56∶44)为流动相
流速1.0 mL.min-1
柱温35℃
检测波长370 nm。结果:在0.020 6~0.133μg进样量范围内
槲皮素含量与峰面积呈很好的线性关系(r=0.997)
平均回收率为98.2%
RSD为1.70%。5批样品中槲皮素总量均值为1.44 mg.g-1。结论:该方法简便
准确
重复性好
可用于苗药黑白保肝清颗粒中槲皮素总含量测定。
Abstract
Objective:To establish a method to determine quercetin in Heibai Baoganqing Granules of Mao ethnomedicine by HPLC.Method:HPLC was used.The column was Diamonsil(TM) C18(4.6 mm × 250 mm
5 μm).The mobile phase consisted of methanol-0.2% phosphoric acid(56∶ 44)
with the flow rate of 1.0 mL.min-1and the wavelength was at 370 nm.Result:Quercetin was linear in the range of 0.020 6 ~ 0.133 μg.The average recovery was 98.2%.The average content of quercetin in five samples was 1.44 mg.g-1.Conclusion:This method is accurate
simple and reproducible
and can be used for the determination of quercetin in Heibai Baoganqing Granules.
