ABSTRACT
Objective: To establish a method for determination of methone and pulegone in Herba Schizonepetae. Methods: The contents of menthone and pulegone were determined by GC (equipped with FID) with HP-5 fused capillary column (5% phenyl methyl siloxane 30m?0.32mm?0.25?m) after the samples were extracted by the solvents. Results: The linear ranges were 0.002-5.0g/L (r=0.9999) for menthone and 0.002-5.0g/L (r=0.9996) for pulegone, the recoveries of menthone and pulygone were 96.30%-103.9% and 95.7%-102.5%, respectively. Conclusion: The method was simple and accurate, which could be applied to the determination of menthone and pulegone in Herba Schizonepetae.
