Abstract:
OBJECTIVE To determine the contents of furfural, camphor, benzoaldehyde, 4-carvomenthenol, α-terpineol and borneol of Jian'er Qingjie solution from different manufacturers.
METHODS The six components were analyzed by capillary columns gas chromatography with HP-INNOWAX capillary column. Cyclohexanone was used as internal standard substances. The injector temperature was 200℃, the detector temperature of FID was set at 220℃.
RESULTS The linear ranges of six components were 5.139-128.467 μg·mL
-1(
r=0.999 90), 1.900-47.500 μg·mL
-1(
r=0.999 37), 6.537-163.436 μg·mL
-1(
r=0.999 96), 1.057-26.423 μg·mL
-1(
r=0.999 38), 2.398-59.958 μg·mL
-1(
r=0.999 23) and 1.014-25.346 μg·mL
-1(
r=0.999 36), respectively. The recoveries were 97.0%, 99.3%, 98.6%, 94.6%, 93.5%, 101.2%, respectively. The content of the above components in Jian'er Qingjie solution produced by different manufacturers is quite different.
CONCLUSION The method can contribute to the improvement of Jian'er Qingjie solution quality standard by providing scientific data.
