Extraction and Quantification of Some Plants Extracts through HPTLC

Abstract

A study of quantitative analysis of some extracts is presented. The HPTLC analyses were performed in a normal chromatographic chamber on silica gel plates, with an appropriate mobile phase. Photodensitometric evaluation of the chromatographic plates was performed by UV-visible absorbance. Quantitative analyses of extracts were performed by use of calibration curves. The quantity of compounds extracted depends on the composition of the extraction solvent and on the extraction technique. The best results were obtained by heating under reflux with systems that contained hydroalcoholic solvent.
