Abstract: | Objective To establish a method for determination of praeruptorin A in Qingre Zhenke syrup. Methods A HPLC method was performed on the chromatographic column of Diamonsil-C,s at a flow rate of 1.0 mL · min^-1. The mobile phase was a mixture of aeetonitrile-water (68:32). The column temperature was 30 ℃, and the detection wavelength was 321 nm. Results The linear range of praeruptorin A was 4.4-27.5 μg · mL^-1 (r= 0.999 5). The average recovery for praeruptorin A was 99.4% (n = 6). Conclusion The method could be used for the auantitative determination of the nrenaralion. |
