Abstract

Oxidative stress can lead to tissue damage and result in disease or aggravate existing disease. Antioxidants are required to protect cells from free radical damage. Temulawak (Curcuma xanthorriza L.) and turmeric (Curcuma longa L.) are natural ingredients with polyphenol compound. Polyphenols has antioxidants that can neutralize free radicals by donating an electron or hydrogen atom. This study was aimed to determine the antioxidant properties of temulawak extract (TLE) and turmeric extract (TE). The antioxidant activity were determined using total phenolic content (TPC), total flavonoid content (TFC), 2,2 diphenyl 1 picrylhydrazyl (DPPH), 2,2′-Azinobis(3-Ethylbenzthiazoline-6-Sulfonate) (ABTS), hydrogen peroxide (H2O2), NO (Nitrogen Oxide) scavenging and ferric reducing antioxidant power (FRAP). The result showed that the TPC of value was 10.93 µg GAE/mg extract, and the TFC value was 5.67 µg QE/mg extract. Meanwhile, TPC and TFC value of TLE were 4.83 and 2.68 µg GAE/mg, respectively. The IC50 value of DPPH, ABTS, H2O2, NO scavenging activity and FRAP activity of TE were 300.7; 39.19; 86.83; 88.03 µg/mL and 493.75 μm Fe (ii)/μg respectively compared to TLE 197.5; 82.55; 205.94; 164.25 µg/mL and 451.00 μm Fe (ii)/μg respectively. Turmeric has higher antioxidant properties than temulawak, both turmeric and temulawak are potential natural antioxidants.
