The objective of the present study was to formulate effervescent and fast dispersible granules by incorporating the fruit extract of Emblica officinalis as an alternate of liquid herbal juices available in market. Amla juice was extracted manually and then subjected to preliminary phytochemical screening which indicates the presence of alkaloids, glycosides, flavonoids, carbohydrates, phenolic compounds, proteins and phytosterols. Lyophilized amla powder was used to formulate effervescent and fast dispersible granules which were further opt imized on the basis of concentration of superdisintegrants and effervescent producing agents like croscarmellose sodium, sodium starch glycolate, sodium bicarbonate and citric acid. Powdered formulations were then evaluated on basis of their flow properties like angle of repose, bulk density, tapped density, carr’s index, hausner’s ratio, effervescent cessation time and disintegration time. Among all the effervescent formulations F2 was found to be optimum as it was having least disintegration time of 22 seconds and showed excellent flow properties. In case of the fast dispersible formulations the optimum strength were shown by formulations F9 having croscarmellose with least disintegration time of 52 seconds. Total phenolic content of fresh amla juice were found to be 8.94 mg GAE/100 gm and estimation of ascorbic acid and gallic acid in lyophilized amla powder and developed formulations was carried out by HPTLC. In vitro antioxidant activity of lyophilized amla powder was evaluated by DPPH radical scavenging assay. IC50 value of lyophilized amla powder was found to be 32 ± 0.25 ug/ml calculated in comparison to standard ascorbic acid possessing IC50 value of 25.80 ± 0.2 ug/ml. Results of present study reveals that developed formulations may serve as alternate product with better quality, consistency and stability in comparison to available herbal liquid formulations.
