Abstract:
OBJECTIVE:To compare the contents of eucalyptol in Artemisia argyi of 5 different planting densities. METH-ODS:Gas chromatography method was performed on the column of HP-5 capillary column,and cyclohexanone was selected as in-ternal standard,the carrier gas was nitrogen at a flow rate of 0.6 ml/min,the volume temperature was 240℃,the detector tempera-ture was 250 ℃,the split ratio was 10∶1,and the injection volume was 1 μl. RESULTS:The linear range of eucalyptol was 0.420 4-1.261 2 mg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 0.92%;average recovery was 99.6%(RSD=1.4%,n=6). CONCLUSIONS:The method is simple,rapid,accurate,reliable and reproducible,and can be used for the content determination of eucalyptol in A. argyi. The optimal planting density of A. argyi was spaced 30 cm×40 cm.
