The activities of some enzyme like amylase, cellulose, invertase lipase and protease were studied in locally available two varieties (green and red) of water chestnuts, an Asian aquatic fruits popular for its nutritive value and medicinal properties. All the tested enzyme activities were found slightly higher in green variety than in red variety. The amylase, cellulase, invertase, lipase and protease activities were 0.3532, 0.1922, 0.0587, 0.0234 and 0.0548 mg/ml/min, respectively in green variety and 0.2514, 0.1221, 0.0520, 0.0204 and 0.0515 mg/ml/min, respectively in red variety. From the enzyme activity assay it was found that water chestnuts might be used as a source of some enzymes such as amylase, cellulase, invertase, lipase, protease etc. These enzyme activity could be major factor for determine the nutritive and medicinal value of the water chestnuts.
