Objective: To establish a method for the determination of tirucallol
euphol and 24-methylene cycloartanol in Euphorbiae Pekinensis Radix and its processed products. Method: An HPLC method had been developed for detecting. The separation was performed on an Agilent XDB C8 column (4.6 mm×150 mm
5 μm) at 35 ℃ with acetonitrile-H2O (90: 10) as the mobile phase. The flow rate was 1.0 mL·min-1
and the detection wavelength was set at 205 nm. Result: The linear response range was 0.506-5.06 μg (r=1.000 0) for tirucallol
1.05-10.5 μg (r=0.999 9) for euphol and 1.12-11.2 μg (r=0.999 8) for 24-methylene cycloartanol. The average recoveries of these components were 99.7% (RSD 0.9%)
99.4% (RSD 1.0%) and 99.4% (RSD 1.3%) respectively. Conclusion: The method is simple
accurate and reproducible for quality control of Euphorbiae Pekinensis Radix and its processed products.
