High performance thin layer chromatography qualitative densitometry as a sensitive method to assess shelf life of polyherbal formulations: A study on Hutabhugadi Churna.

Introduction: Measuring chemical stability of polyherbal formulations is very challenging due to diversity in phytochemical composition. As there are no comprehensive guidelines for stability testing of herbal products, there is a need for a sensitive tool to detect how the quality of herbal products varies with time under the influence of environmental conditions.

Aims: To validate the employability of high-performance thin layer chromatography (HPTLC) for real-time stability of Hutabhugadi Churna (HC).
