Tea plant (Camellia sinensis L.) had been known to contains epigallocathecin gallate (EGCG) that can be used to maintain the healthy. In this research, the green tea was tried to be formulated in effervescent dosage form, with the focus on the effect among fumaric acid, sodium bicarbonate, and the interaction between fumaric acid and sodium bicarbonate on the green tea extract effervescent granuleâs physical properties, that made by dry granulation method. Physical properties of effervescent granule that been study were moisture content, flow rate, disintegration time, and pH of the solution. The result showed that sodium bicarbonate was dominant in determining pH, granule flow rate and moisture content of granule, whereas fumaric acid dominant in disintegration time of effervescent granule.Key words: green tea, fumaric acid, effervescent granule, dry granulation
