ABSTRACT

[Objectivej To establish a gas chromatography (GC) method for the determination of the content of camphor, isoborneol and borneol in Anmo Ointment. [ Methods ] The determination was performed by programmed temperature GC, in which a 100% concentration of dimethylpolysiloxane was used as stationary liquid phase and the GC was equipped with FID detector at 300℃. [Results] The isolation and the linearity were fine with the rate of recovery of camphor 100.5% (RSD being 1.4%), isoborneol 99.1% (RSD being 1.8%) and borneol 100.8% (RSD being 1.3%). [Conclusion] This method is sensitive, rapid and accurate. It can be used to control the quality of Anmo Ointment.
