General works Nutrition Antioxidants Ginger (Zingiber officinale Roscoe) contain various bioactive constituents and properties that are beneficial for health. Some of local ginger that are widely used as traditional medicine are ginger Bara and ginger Bentong. This study was conducted to detem1ine and compare antioxidant, total phenolic and total flavonoid content of methanolic extract from both gingers. Antioxidant properties of both ginger were assessed by DPPH assay with ascorbic acid as positive control. The quantification of antioxidant showed that ginger Bara had higher percentage of inhibition, 91.98 ± 1.05. Besides that, determination of total phenolic content in methanolic extract of both ginger required gallic acid standard curve to be plotted. Ginger Bara had higher total phenolic content with 8.83 ± 0.06 mg gallic acid/g of dry plant material. Moreover, highest total content of flavonoid also can be found in ginger Bara with 0.46 ± 0.01 mg quercetin/g of dry plant material. In general, the study shows that ginger Bara have higher antioxidant properties, as well as phenolic and tlavonoid content in comparison with ginger Bentong. Hence, the medicinal potential of ginger Bara was validated. 2019 Student Project NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/42437/1/42437.pdf Nor Izwan, Nur Elyisa (2019) Antioxidant, total phenolic and fla vonoid content in two different species of ginger / Nur Elyisa Nor Izwan.
