Development of HPTLC fingerprinting method for estimation of gallic acid in polyherbal capsule

Abstract

The aim of present study is to develop a simple, specific, accurate and reproducible HPTLC method for the
quantitative estimation of gallic acid in raw and poly-herbal capsule dosage form The fingerprinting method was
developed for raw materials Eugenia jambolana (bark), Phyllanthus niruri (whole plant) and laboratory batch
polyherbal capsule via estimation of gallic acid by using HPTLC methods. The results indicate the presence of
optimum level of gallic acid in raw as well as laboratory batch of prepared polyherbal capule.
