| Objective To establish a method for the determination of menthone and menthol in Toning lotion. Methods Gas chromatographic(GC) method was used to determine menthone and menthol content in Toning lotion.Column:Agilent DB-WAX Capillary Column(30 m×0.32 mm,0.5 μm);programmed temperature.The temperature of injection port was 260 ℃,and detector temperature was 280 ℃,the detector was FID. Result Good linear correlation for menthone and menthol were found respectively in the range of 0.049 08~0.981 6 μg(r=0.999 1) and 0.044 9~0.898 0 μg(r=0.999 5),the average recoveries of the 2 constituents were 98.76% and 99.60%,with RSDs of 2.25% and 1.96%. Conclusion The established method is accurate,easy to operate and with good reproducibility,which can be used for the determination of menthone and menthol content in Toning lotion. |
