phenolic content and antioxidant activity of jahe gajah oil. The total phenol
content was determined using Folin-Ciocalteu method and the antioxidant
activity assay was done using DPPH method. The total phenol content for jahe
gajah oil was 0.626 ± 0.022 mg GAE/g . The IC50 of jahe gajah oil was 5,766 ±
0,087 µl/ml. Antioxidant activity from jahe gajah oil was suggested to be
contributed by the phenolic compound and result from synergistic action of all
