Antioxidant activity of Hylocereus undatus foliage using different method

Hylocereus undatus or commercially known as white dragon fruit contains high antioxidant activity. The Hylocereus undatus foliage is believed to have high antioxidant activity compared to pulps and peels. Antioxidant activity was extracted by two different solvents namely methanol and chloroform using Ferric Reduction Antioxidant Power assay (FRAP). In determining antioxidant activity, the results show that the yield of methanol extract (44.44%) is higher than chloroform extract (22.22%). A comparison was made between findings from this study with the previous studies. The results revealed that the antioxidant activity obtained from methanol extract (59.05%) and chloroform extract (20.58%) using FRAP assay were comparable to the methanol extract (88.81%) and chloroform extract (38.30%) using DPPH assay based on the previous study.
