Abstract

Myristica fragrants (nutmeg) is a tropical fruit in Banda Island. It is also used to cultivate in the South of Thailand. It is used as conventional medicine for disease prevention and treatment. However, there are no research studies about its antioxidant activities using ethanol solvent. The total phenolic content and antioxidant capacity in different parts of ethanolic extract (pulp, mace and seed) from nutmeg were evaluated. Dried samples were extracted using 95 % ethanol, while Folin-Ciocalteu assay was employed to determine total phenolic content. Whereas, antioxidant activities were determined by ferric reducing antioxidant power and DPPH assay. The results revealed that the nutmeg seed contained the highest total phenolic content, which was 465.91 ± 03 mg GAE/100 g DW. For antioxidant activity, the nutmeg seed possessed the highest inhibited DPPH (IC50 = 4.6 ± 15 mg/L) and the highest ferric reducing antioxidant power values (542.39 ± 22 μmol TE/100 gDW), which were significantly higher than reference standard. Phenolic compounds in nutmeg samples have exhibited strong correlation with antioxidant capacity. Therefore, nutmeg, especially nutmeg seed is potentially functional food with high antioxidants.
