摘要:

建立并验证了苦参功劳颗粒中盐酸小檗碱的含量测定方法。采用高效液相色谱法,色谱柱为Agilent Zorbax SB-C18(250 × 4.6 mm,5 μm),流动相为乙腈-0.05mol/L磷酸二氢钾缓冲液；检测波长为265 nm；流速为1.0 ml/min；柱温为30 ℃。试验结果表明盐酸小檗碱在4.9~78.6μg.ml_^-1范围内,峰面积与浓度呈良好的线性关系(r = 1),加样回收率在101.38%-103.74%之间,平均回收率为102.7%, RSD=0.8%(≤2.0%)。所建立的方法简便、准确度高、专属性强,可用于苦参功劳颗粒中盐酸小檗碱的含量测定。

Abstract:

A method for determining the content of berberine hydrochloride in Kushen Gonglao Granules was established and verified. Using high performance liquid chromatography, the column was Aglient Zorbax SB-C18 (250 × 4.6 mm, 5 μm), and the mobile phase was acetonitrile-0.05mol/L potassium dihydrogen phosphate buffer; the detection wavelength was 265 nm; the flow rate was 1.0. ml/min; column temperature is 30°C.The results showed that the berberine hydrochloride injection concentration ranged from 4.9 to 78.6μg.ml-1, and the peak area showed a good linear relationship (r=1). The recovery test was between 101.38% and 103.74%. The recovery test was 102.7%, and RSD was 0.8% (≤2.0%). The established method is simple, accurate and specific, and can be used for the determination of berberine hydrochloride in Kushen Gonglao Granule.
