OBJECTIVE
To establish the determination method of pulegone in Herba Schizonepetae.
METHOD
HPLC method was developed for the determination of pulegone in Herba Schizonepetae. The separation was performed on C18 column with MeOH-H2O (80:20) as a mobile phase. The detection wavelength was set at 252 nm.
RESULT
The quantitation of pulegone in Herba Schizonepetae varied from 0.2-0.7 mg x g(-1). The average recovery is 96.2%, RSD 0.81%.
CONCLUSION
The method is simple, rapid and accurate.
目的
建立荆芥中胡薄荷酮的测定方法。
方法
采用高效液相色谱法测定荆芥中胡薄荷酮的含量。色谱柱为C18柱，以甲醇-水（80:20）为流动相，检测波长为252nm。
结果
荆芥中胡薄荷酮的含量为0.2 - 0.7mg·g⁻¹，平均回收率为96.2%，相对标准偏差为0.81%。
结论
该方法简便、快速、准确。
