Determination of spinosin in Anshenbao granule by HPLC / 国际中医中药杂志

Objective To establish a HPLC method for the determination of Spinosin in anshenbao granule. Methods The HPLC was adopted with Phenomenex LUNA-C18(4.6 mm×250 mm, 5μm)column, and the mobile phase consisted of Acetonitrile(19)-0.005 mol/L Kaliumdihydrogenphosphorate(81). The flow rate was 1.0 ml/min, the column temperature was 30℃ and the UV detector was set at 250 nm. Results The linear response range was 1.83~36.60μg/ml(r=0.9998). The average recovery of spinosin was 98.4%, and RSD1.22%. Conclusion The method was simple, rapid, accurate and repeatable. It can be applied in determination of spinosin in Anshenbao granule.
