HPTLC and UPLC-MS/MS Methods for Quality Control Analysis of Itrifal Formulations of Unani System of Medicine.

Abstract

Ultra-performance LC (UPLC)-tandem MS (MS/MS) and high-performance TLC (HPTLC) assay methods were developed for chemical fingerprinting and quantitative analysis of bioactive constituents of a certain "Itrifal formulation," a traditional kind of Unani medicine. In the present investigation, HPTLC and UPLC-MS/MS methods were developed and validated for the detection and quantification of major metabolites present in itrifal formulation. The metabolites present in the formulation were separated using modern chromatographic techniques, and a quantitative analysis was performed. Analytical performance of the proposed HPTLC and UPLC-MS/MS methods was validated as per the defined guidelines with respect to linearity, accuracy, precision, robustness, and specificity. The developed UPLC-MS/MS and HPTLC methods were used for quantification of gallic acid, tannic acid, catechin, and quercetin. All four constituents were quantified by UPLC-MS/MS, while two constituents were quantified by HPTLC in the commercial itrifal formulation. The calibration plot was found to be linear, accurate, precise, robust, and specific for both HPTLC and UPLC-MS/MS. The present methods were successfully applied for analysis of the given markers in itrifal formulations. The same can be used for QC and stability testing of itrifal formulations.
