Accepted on 17 December 2014 _____________________________________________________________________________ ABSTRACT One new isoquinoline alkaloid (1), three quercetin glycosides (2-4) and a triol (5) were isolated from the methanol extract of leaves of Annona cherimola. Quercetin glycosides and a triol were first time reported from this plant. The structures were confirmed by H, C, 2D NMR spectroscopy and mass spectral data. Compounds 2-4 are found showing prominent antioxidant activity against superoxide radical, DPPH, FRAP, ABTS and moderate anti-inflammatory activity against 5-LOX. The IC50 values of compounds 1-4 are 24.29, 5.98, 9.11, 2.87 μg mL respectively against DPPH radical showing high antioxidant activity of compound 4.
