Abstract : Water sorption of a denture base resin can trigger discoloration and halitosis as well as dimensional instability, leading to internal stress and ultimately to cracks or failure of the denture. In other words, a high water sorption rate tends to affect the material properties and consequently reduce the service life of a denture within the oral cavity; therefore, it is crucial to use materials with minimum possible water sorption rates. 60 specimens were fabricated from metal patterns according to ADA specification to evaluate water sorption and solubility of heat cured acrylic resin after immersion in peppermint and pomegranate extracts, at two different periods (2 weeks and 4 week). The highest mean value for water sorption was obtained by control group at the 4-week period (0.6354). Whereas the lowest mean value was recorded by peppermint group at the period of 2 weeks (0.6291), for solubility test, the highest mean solubility value was obtained in control group at the 4-week period (0.0315). Whereas the lowest mean value was obtained in peppermint group at the period of 2 weeks (0.0211). comparing with control group. There was a non-significant difference P˃0.05 in the mean value of water sorption and solubility test for all experimental groups (with each other’s and with control group) after two immersion periods
