Abstract

Objective To establish gas chromatography(GC) method for separating and determining both borneol and menthol in tanxiang tongmai capsule.Methods Naphthalene served as an internal standard,acetic ether as a solvent,10% PEG-20M as separation,nitrogen as the carrier gas.Column temperature was set at 130 ℃,and injector and detector temperature was 180 ℃.Sample size was 1 μL by using flame ionization detector.Results The linear ranges of borneol and menthol were 0.26-2.55 mg·mL-1(r=0.999 9) and 0.26–2.62 mg·mL-1(r=0.999 8),respectively.Recovery rates of borneol and menthol were 97.5%(RSD=1.77%) and 96.81%(RSD=1.28%),respectively.Conclusion This method is convenient,rapid,accurate and reproducible,and can be used for quality control of tanxiang tongmai capsule.
