Evaluation of Antibacterial, Antioxidant and Antiobese Activities of the Fruit Juice of Crabapple Mangrove Sonneratia caseolaris (Linn.)

摘要

A study was carried out to investigate the antibacterial, antioxidant, and antiobese activities of fruit juice of the mangrove plant Sonneratia caseolaris. The fruit juice was prepared by three different methods: water extract of fruit flesh (J1), hot water extract of fruit flesh (J2), and hot water extract of whole fruit (J3). All three juice samples exhibited antibacterial and antioxidant activities, and sample J3 showed the highest activities compared with sample J1 and J2. Sample J3 was then chosen for an antiobese activity test. The results demonstrated that the crabapple mangrove fruit juice had an effect to prevent the increase in body weight of the mice. The study suggests fruit juice of S. caseolaris as a potential source of active compounds with antimicrobial, antioxidative, and antiobesity properties and can be used as natural antibacterial, antioxidative, and antiobesity agents in pharmaceutical and food industries.
