Abstract
The technological improvement in the structural elucidation of natural compounds has made it probable to generate appropriate strategies for the analysis and standardization of plant-based medicines. An appliance of highly oriented hyphenated techniques provides a definite tool for herbal investigations. Therefore, the present study was directed towards the standardization of biomarkers gallic acid and berberine in polyherbal formulation Entoban capsules to ensure the quality of the herbal drugs. A rapid, simple, accurate, and specific high-performance thin-layer chromatography (HPTLC) method for the quantitative estimation of biomarkers berberine and gallic acid has been developed. HPTLC was performed to evaluate the presence of gallic acid and berberine applying toulene—ethyl acetate—formic acid—methanol (12:9:4:0.5 v/v) and ethanol—water—formic acid (90:9:1 v/v), as the mobile phase, respectively. The RF values (0.58 for gallic acid and 0.76 for berberine) in both sample and reference standard were fou...
