- W4320914567 abstract "Phytochemical screening was conducted on H ylocereus u ndatus foliage to determine the presence of alkaloids, flavonoids, tannins, and saponins using methanol and chloroform solvents via oven-dried and open air-dried methods. As for the antioxidant activity, powdered H ylocereus undatus foliage were extracted using both solvents through Ferric Reduction Antioxidant Power (FRAP) assay; and the findings were then compared to 2,2-Diphenyl-1-Ipicrylhydrazyl (DPPH) assay from previous studies. Results revealed that for both methods in phytochemical screening, flavonoids were present only in methanol extract; however, saponins were present in both extracts. No alkaloid and tannins were present in both extracts using both methods. Antioxidant activity results revealed that the methanol extract (59.05%) and chloroform extract (20.58%) using the FRAP assay were comparable to that of DPPH assay in which methanol extract (88.81%) and chloroform extract (38.30%) were obtained. It concludes that H ylocereus undatus has comparable phytochemical constituents and antioxidant activity based on the different drying and assay methods." @default.
