Abstract: The research aimed at unearthing the total levels of selected phytochemicals and the antioxidant (DPPH) in Annona muricata, Ribes nigrum and manilkara zapota plant extracts, which are widely known for their medicinal properties and locally grown in Manchester Jamaica West Indies. The leaves, bark and stem were collected and identified by an agronomist. They were aseptically treated then dried at room temperature for 4 days after which they were milled by the use of dry blend commercial heavy duty blender. The pulverise samples were stored at room temperature in sealed plastic screw top sterile cups until processed. The plants were tested for the presence of Phytochemicals (total flavonoids, total poly-phenols, and total tannins).
