ABSTRACT:
Objective: The objective of this study was developed and validated of a simple, rapid and accurate GC method for quantitative determination of thymol which considers as a chemical marker in thyme extract and in the final formulation by GC-FID chromatography. Method: thymol analysis was done by using menthol as internal standard, chromatographic conditions were TRB-5-625 capillary column and its specification 60m?0.25mm i.d0.25µm film thickness and nitrogen as a carrier gas at a flow rate of 0.6mL/min. The oven temperature was programmed between 185? and 235? for 16min. The injector and detector temperatures were maintained 290?. Detection was done by using flame ionization detector FID. Results: the developed method was validated according to ICH guidelines. The developed method was given accepted linearity which R>0.99 in the concentration range of 1-40mg/10ml of thymol, accuracy with mean recovery values between 98%-102%, precision with relative standard deviation of the calculated concentration was less than 2%. Conclusion: The results showed that the developed method was effective in determination of thymol in pharmaceutical forms and routine analysis in quality control laboratories simply.
