ABSTRACT

Objective To establish an HPLC-ELSD method for the determination of pinitol in Fufang Kushen Injection. Methods Chromatographic condition was as follows:Cosmosil Sugar-D column (250 mm×4.6 mm, 5 μm), the mobile phase consisting of acetonitrile-water in gradient mode, the temperature of the drift tube of 77 ℃, and the gas flow rate of 2.0 L/min. Results The standard curve of pinitol was rectilinear within the range of 0.5-10.0 μg, r=0.999 6 (n=5). The average recovery was 97.30%(RSD=1.29%, n=5). Conclusion The method is simple and rapid, the result is accurate, reliable and reproducible.
