ANALYTICAL METHOD DEVELOPMENT AND ITS VALIDATION FOR THE ESTIMATIONOF THYMOL IN TACHYSPERMUM AMMI MILL FRUIT BY GAS LIQUID CHROMATOGRAPHY
AbstractThymol is the main volatile compound extracted from dried fruits of Tachyspermum ammi Mill. The compound serves as a biological marker because of its interesting biological activities and is used in traditional medicine, as a bactericide, fungicide, Gastro-intestinal disorders, Bronchitis and asthma, and others. A GC method for the determination of thymol was developed. Chromatographic analysis was carried out on – stainless steel 30m×0.25m×0.25mm packed with polysiloxane column with flow rate 1.0 ml per minute of the carrier gas. Quantification was performed using a FID. The method was validated for specificity, precision, Linearity, accuracy and robustness. The method was found to be precise for different concentrations of thymol. Accuracy was checked by conducting recovery at different level of thymol and the average percentage and recovery was found to be in the range 90%-110%. The Linearity was established over a range of seven different concentrations of the analyte (70%, 80%, 90%, 100%, 110%, 120% and 130% of test concentration) with correlation coefficients of 0.9997 for thymol.
