| Abstract | Hom Thong Banana is a popular edible fruit with all of its parts having medicinal applications. It contains a variety of biologically active phenolic compounds and flavonoids which exhibit excellent antioxidant and antimicrobial activities. The objective of this study was to determine total phenolic content (TPC) and antioxidant activities from different parts of Hom Thong Banana by various extraction conditions. The antioxidant activities were determined by FRAP, DPPH and ABTS methods. Parts of banana used in this study were leaves, leaf stems (petioles), pseudostems, stalks, ripe and unripe peels. In the initial study process, it was found that the parts that contained the highest TPC were the leaves and the unripe peels. These 2 parts were then used in the comparison of the extraction conditions. The optimal extraction condition that gave the highest total phenolic content and antioxidant capacity by FRAP, DPPH and ABTS tests was using 70%ethanol as an extracting solvent at 55oC for 4 hours. The unripe banana peels' extract had a TPC of55.94mgGAE/g and an antioxidant capacity of 59.58, 138.63 and 276.60 mgAE/g from FRAP, DPPH and ABTS tests, respectively, which was higher than those values from the banana leaves extract. The unripe banana peels demonstrated superior antioxidant activities, which would be worth selecting for further development |
