Objective To establish the student experimental method of measuring the content of camphor and eucalyptol in Shidishui tincture by gas chromatography. Methods SE-54 capillary column (30 m×0. 25 mm×0. 25 μm) was used in the experi-ment. The injector temperature was 230 ℃ , and FID detector temperature was 240 ℃ . The Temperature was programmed with the ini-tial 70 ℃ and the final 160 ℃ , increasing at the speed of 8 ℃ ·min-1 . Results The average sample recovery rates of camphor and eucalyptol in the experiment were 98. 3% and 97. 6% respectively, and RSD were 1. 9% and 2. 1% respectively. Conclusion The method can be applied to student experiment teaching for its simplicity and high accuracy.
