Abstract:
OBJECTIVE:To establish a method for content determination of eucalyptol in Chimonanthus Zhejiangensis. METH-ODS:GC was conducted with Zebron ZB-WAX capillary column with temperature programmed;FID detector was used with the temperature of 250 ℃;the volume temperature was 220 ℃ and the carrier gas was nitrogen with high purity. RESULTS:Eucalyp-tol had a good linear relationship in the range of 0.017 69-1.415 mg/ml(r=0.999 1);the RSDs of precisions,stability and reproduc-ibility tests were no more than 1.87%and the average recovery was 99.72%(RSD=0.65%,n=6).There were big differences in dif-ferent areas of the same month and the maximum was more than one time (1.064%-0.450%);there were also big differences in the same area of different months(0.633%-1.064%). CONCLUSIONS:The method is simple,accurate,fast and reproducible and suitable for the quality control of Chimonanthus Zhejiangensis.
