Abstract

Objective: To establish a GC method for determination of menthol, camphor and methylsalicylate in Cremor Mentholi Compositus. Methods: The determination was carried out on a PEG\|20M stainless steel column with temperature at 140℃, FID detector with temperature at 260℃. Results: The separating degree and the linearity were fine with the average recovery of menthol 100.17%, RSD =0.661%; camphor 99.89%, RSD =0.600%; methylsalicylate 100.17%, RSD =0.553%, respectively. Conclusions: The method is convenient, rapid and accurate. It can be used to control the quality of this preparation.
