Purpose: Nypa fruticans Wurmb. is one of the underutilized fruit of Malaysia. Antioxidant capacity of immature and mature fruits was evaluated.
Findings: Total phenolic and flavonoid content of immature fruits were higher (6.08±0.1 mg GAE/g and 3.3±0.5 RE/g respectively), than mature fruits. Also, immature fruit showed high DPPH radical scavenging activity of 75.7±1.1% and antioxidant capacity (A=1.3), even higher compared with BHT and mature fruits.
Practical implications: Both immature and mature fruits exhibited excellent inhibition of RBC hemolysis and moderate hemoglobin oxidation.
Value: Hence, this fruit has the potential to be promoted as a natural source of antioxidant.
