Methods Gas chromatography,the ZB-WAX elastic quartz capillary column(30 m × 0. 25 mm,0. 25 μm);Dyclohexanone as internal standard. Results The linear range of eucalyptol and menthol was 0. 146~2. 555 mg·mL-1 (R2 =0. 999 9),0. 198~3. 465 mg·mL-1(R2 =0. 999 8);The average sample recovery rates were 99. 8%,99. 5%,re-spectively(n=9),the minimum quantitative limit concentrations of eucalyptol and of menthol were 6. 27,9. 90μg·mL-1;The minimum detection limit concentrations were 1. 044,1. 65 μg·mL-1 . Conclusion The method was simple,rapid,ac-curate,good separating degree,no interfere with other ingredients and was applicable to many ingredients in the compound preparation of quality control.
