Objective: To establish a gas chromatographic method for the simultaneous determination of thymol and carvacrol in Herba Thyma. Method: The GC system consisted of capillary column(0.25 μm×0.32 mm
30 m)
FID detector
nitrogen as carrier gas
column temperature programmed
the initial temperature of 50℃
detector temperature of 230℃. Result: The content of thymol and carvacrol in 8 batches of samples was determined
thymol and carvacrol were separated well under the chromatographic conditions. The recoveries of thymol and carvacrol were 99.29%(RSD 2.51%)
99.07%(RSD 2.92%). Conclusion: The method was sensitive
accurate and specific
which is suitable for the quality control of Herba Thyma.
