Gallic acid (GA) is an isolated secondary metabolite from Terminalia chebula, a common medicinal plant regularly used in the traditional preparation of several formulations in Indian system of medicine –Ayurveda. Extraction and processing of plasma samples containing GA from animals is a bit challenge due to its instability. Plasma samples were extracted with and without acidic environment and observed that hydrochloric acid addition has showed better extraction and recovery of GA. Later different formulations have shown very fast absorption and elimination half-life of GA in mice and rats.
