Application of TLC-Spectrodensitometric and Chemometric Methods for Determination of Momenta® Cream: A Comparative Study Applied on Ternary Mixture

Abstract

A comparative study for the validation and advancement of two analytical approaches applied for the simultaneous determination of Mometasone Furoate (MF), Miconazole Nitrate (MIC) and Gentamicin (GM) formulated in Momenta® cream. The first approach was TLC-spectrodensitometric method, which was advanced by separating the three components on TLC aluminum plates coated with silica gel 60 F254 using chloroform: methanol: formic acid (4:0.3:0.15, v/v/v) as a mobile phase, then scanned at 254nm using Camage TLC scanner 3 operated in reflectance-absorbance mode. The second approach was the chemometric method using two models: Partial Least Squares (PLS) and Principle Component Regression Model (PCR). The proposed approaches were validated according to ICH guidelines and were applied for the determination of the ternary mixtures in their analytical mixtures and pharmaceutical preparation.
