HPLC法测定舒利通颗粒中巴马丁和小檗碱的含量
摘要
目的:建立以高效液相色谱法测定舒利通颗粒中巴马丁和小檗碱含量的方法。方法:色谱柱:Kromasil-C18(250mm×4.6 mm
Objective:To develop a HPLC method for the determination of palmatine and berberine in Shulitong Granule.Methods:A Kromasil-C
18
(250 mm×4.6 mm
5 μm)column was used for the HPLC determination.The mobile phase consisted of acetonitrile-0.1 mol/L potassium dihydrogen phosphate(28∶72)
and the flow rate was 1 mL/min.The detection wavelength was 345 nm.Results:A good linear relationship was constructed in the range of 0.016~0.080 μg(r=(0.999 8))
for Palmatine hydrochloride and in the range of 0.027~0.135 μg(r=(0.999 9)) for berberine hydrochloride. The average recovery of palmatine hydrochloride was 99.74%(RSD=2.67%
n=5)
and that of berberine hydrochloride was 103.53%
RSD=1.48%(n=5).Conclusion:The developed method is simple
reproducible
specific and suitable for the quality control of Shulitong Granule.
