This research introduces a novel stability-indicating HPTLC (High-Performance Thin-Layer Chromatography) method for the comparative quantitative estimation of Quercetin in herbal preparations. Through extensive stability studies, the method is validated, providing a robust framework for evaluating Quercetin's stability in diverse herbal formulations. The developed method ensures accurate and reliable quantification of Quercetin, facilitating comparative analysis across various herbal preparations. Additionally, results reveal that Quercetin degraded under most tested conditions, such as acidic, alkaline, oxidative and neutral conditions underscoring the necessity for intervention by experts to eliminate such challenges and ensure product efficacy and quality in the herbal industry.
