Abstract :In this study, changes in angiotensin-I converting enzyme insert ignore into journalissuearticles values(ACE); inhibitory, α-amylase inhibitory and antioxidant activities, total phenolic content insert ignore into journalissuearticles values(TPC);, total monomeric anthocyanin content insert ignore into journalissuearticles values(TMAC); of ultrasonic phenolic extracts from pulp and seed of Ziziphus jujuba were investigated during in vitro digestion. Bioaccessible fractions of phenolics in seed and pulp extracts were calculated as 23.24±4.46% and 9.43±0.24%, respectively. Moreover, bioaccessibility for TMAC in seed extracts insert ignore into journalissuearticles values(147.83±9.20%); was higher than pulp insert ignore into journalissuearticles values(15.76±3.89%); insert ignore into journalissuearticles values(P<0.05);. A decrease in the antioxidant activity of the extracts occurred after in vitro digestion insert ignore into journalissuearticles values(P<0.05);. The ACE inhibitory activity of undigested extracts from seed insert ignore into journalissuearticles values(86.04±0.00%); was higher than that of the undigested pulp extract insert ignore into journalissuearticles values(42.74±8.57%); insert ignore into journalissuearticles values(P<0.05);. The α-amylase inhibitory activity of seed and pulp extracts was determined as 49.18±0.35% and 36.07±5.83%, respectively. The results of the study showed that ACE inhibitory activity and α-amylase inhibitory activity of the polyphenolics from pulp increased after in vitro digestion.
