GRAPHICAL ABSTRACT


ABSTRACT


LC-DAD-UV and LC-ESI-MS-based analyses were performed in order to chemically characterize a phenol-enriched fraction obtained from Iryanthera ulei leaves-derived ethanol extract. Eight glycosylated flavonoids, two free-flavonoids and two neolignans were detected to be part of its isopropyl acetate-soluble (iPS) fraction. Presence of afzelin 1 was confirmed by isolation. Total Phenolic (TPC) and Total Flavonoid Contents (TFC), Antioxidant Capacity (DPPH, ABTS • + , and FRAP methods), as well as antimicrobial activity against five strains were determined.
