The objective of the present study is formulation and optimization of effervescent tablets of green tea extract. Health benefits of green tea such as antioxidant, anti-diabetic, anti-cancer, antihypertensive, antimicrobial, anti-inflammatory, coronary heart disease, etc., are attributed to the presence of catechins, particularly (-)-epigallocatechin-3-gallate, as indicated by in-vitro, invivo as well as clinical studies. Extraction of green tea extract, standardization of extract, formulation of tablets and optimization of formulation were carried out. Physicochemical and phytochemical screening were performed. Estimation of polyphenolic content and flavonoid content in lyophilized extract of green tea was carried out. The formulation F5 passed all the evaluation test parameters with shortest effervescent time, better hardness, and friability results. One tablet of our formulation can act as a substitute for one cup of green tea.
