ANTI-BACTERIAL, CYTOTOXICITY, AND ANTIOXIDANT PROPERTIES OF THE ISOLATED FLAVONOIDS EXTRACT FROM WHITE DRAGON FRUIT (HYLOCEREUS UNDATUS) PEELS AND FLESH

The presence of flavonoids in white pitaya’s flesh and peel was confirmed using the Thin Layer Chromatography Screening method. Flavonoid extracted solvent fractionation then subjected to three assays. Using Kirby-Bauer method, better antibacterial activity against E. coli found 100% extract, partially active at 10.28 mm. flavonoid extract inactive both S. aureus concentrations 100%, 75%, 50%. have potential as anticancer agents since they are active, toxic, potent, with LC50 less than 1000 ppm Brine Shrimp Lethality Assay. a UV VIS spectrophotometer 517 nm, antioxidant potential. However, percent Radical Scavenging Activity close catechin control is antioxidant. This study proved that White Pitaya, particularly its flavonoid, medical benefits, can be source income for farmers, decrease waste environment.
