Nabeez water is a kind of infused water from Ajwa palm date fruits that are consumed by Muslim societies in Indonesia especially when Ramadan, unfortunately, its ability to scavenging free radicals have never been studied. The aim of the study was to determine the antioxidant activity of Nabeez water by DPPH methods. Infused water from Ajwapalm date fruitswere made with maceration for 24, 48 and 72 hours with three times replication. The stability contact time result was 60-100 minutes, and maximum wavelengths result was 516 nm.IC50 calculation results showed that at the 24-hour maceration IC50 value was 223.6 ppm, while at 48-hours maceration was 369 ppm, and at 72-hours maceration was 2530 ppm. It can be concluded that the best antioxidant activity achieved at of 24-hour maceration. © Published under licence by IOP Publishing Ltd.
