Objective To establish a GC method to determine the content of borneol in Shezhi Ointment. Methods GC method was operated on Quartz capillary column(30 m×0.25 mm×0.25 μm). Column temperature was increased by programming,with an original temperature at 110 ℃kept for 0.5 minutes,raised to 140 ℃ at the rate of 30 ℃·min-1 and kept for 2 minutes,raised to 190 ℃ at the rate of 50 ℃·min-1 and kept for 1.5 minutes,and then raised to 205 ℃ at the rate of 20 ℃·min-1 and kept for 1 minute. Split ratio was 10∶1 and FID temperature was 280 ℃. Results The linear range of borneol in Shezhi Ointment was from 0.0516 to 0.1548 mg/mL. The linear equation was Y=10.36X+0.0322,r=0.9995. The average recovery was 97.94 %(n=6) and RSD was 2.0 %. Conclusion The method is simple,accurate and quick,which can be used to control the quality of Shezhi Ointment.
