IDENTIFICATION, QUANTIFICATION AND VALIDATION OF STIGMASTEROL FROM ALPINIA CALCARATA USING HIGH-PERFORMANCE THIN LAYER CHROMATOGRAPHY METHOD
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2017, Vol 9, Issue 9
Abstract
Objective: The present study is designed to develop a new simple, precise, rapid and selective highâ€performance thinâ€layer chromatographic (HPTLC) method for the determination of stigmasterol in methanolic rhizomes extract of Alpinia calcarata.Methods: As per International Conference on Harmonization (ICH) guidelines we have applied different concentrations of stigmasterol as standard on HPTLC plates for the quantification of stigmasterol from the Alpinia calcarata rhizomes. The concentration of standard stigmasterol is 1 mg/ml.Results: The retention factor of stigmasterol was 0.58. Linearity was obtained in the range of 50 ngâ€250 ng for stigmasterol. The developed and validated HPTLC method was employed for stigmasterol in methanolic rhizomes extract of Alpinia calcarata for standardization of the content of the marker. The linear regression data for the calibration plots showed a good linear relationship with r=0.99977 for stigmasterol, respectively Satisfactory recoveries of 99.77 % were obtained for stigmasterol.Conclusion: The results obtained in validation assays indicate the accuracy and reliability of the developed HPTLC method for the quantification of stigmasterol in methanolic rhizomes extract of Alpinia calcarata
