目的:HPLC法测定防参止痒颗粒中苦参碱的含量。方法:色谱柱:Diomond C_(18)柱(250 mm×4.6 mm,5μg);流动相:乙腈-无水乙醇-3%磷酸溶液(80:10:10);流速:1.0 ml·min~(-1);检测波长:220 nm。结果:苦参碱在0.05μg~1.98μg范围内线性关系良好(r=1.000 0),平均回收率为100.39%,RSD=0.81%(n=6)。结论:方法简便,精密度好,准确可靠。
OBJECTIVE: To determine the content of matrine in Fang Shen Zhi Yang Granules by HPLC. Methods: Diomond C_ (18) column (250 mm × 4.6 mm, 5 μg) was used as mobile phase. The mobile phase consisted of acetonitrile and absolute ethanol (80:10:10) -1); detection wavelength: 220 nm. Results: The linear range of matrine was 0.05μg ~ 1.98μg (r = 1.000 0). The average recovery was 100.39%. The RSD was 0.81% (n = 6). Conclusion: The method is simple, accurate, accurate and reliable.
