Abstract
A method for determination of Jujuboside A in Semen Ziziphi spinosae milk drink by RP-HPLC was established. The column is Kromasil ODS-1 C18(250 mm×4.6 mm, 5 μm). The mobile phase is acetonitrile- water (34∶66). The UV detector is set at 204 nm. The linear range of the determination is 0.070~0.70 mg/mL with the correlation coefficient of 0.999. The sample solution is stable within 8 h. The average recovery rate was 94.1% with RSD of 1.96% . The method is simple, accurate and specific. It is suitable for the determination of Jujuboside A in Semen Ziziphi spinosae milk drink.
