Abstract
Objective:To establish a method for the determination of matrine in Radix Sophorae Flavescentis.Methods:A Kromasil C18 column(250mm×4.6mm,5μm)with mobile phase consisting of methanol-water-diethylamine(55∶45∶0.02) was adopted,and the detecting wavelength was set at 208 nm. The column temperature was 40℃. The flow rate was 1.0 ml?min-1,and the sample size was 10μl.Results:The calibration curve showed good linearity over the range of 0.05~1.25μg(r=0.9999). The average recovery was 97.62 % with RSD 1.15%(n=6). Conclusion:The method is sensitive,accurate,rapid,and is suitable for the quality control of Radix Sophorae Flavescentis.
