ABSTRACT

Annona squamosa L. (Annonaceae) seed defatted methanol extract produced Quercetin (A), 6- Methoxy isovitexin (B), Kaempferol (C), and Ferulic acid (D). The isolated compounds' structures were verified including 1H, 13C-NMR, IR, and MS spectroscopy analysis. Ascorbic acid (vitamin C) was used as the reference standard for all compounds' in vitro antioxidant properties. The UV- Visible spectrophotometer was used for all of the analysis. The study's findings suggested that each chemical had effective antioxidant activities in a concentration-dependent way. Keywords: Annona squamosa, Phytochemicals, In vitro, antioxidant activity, ascorbic acid
