This studywas conducted to investigate the phytochemical and proximate constituents of leaves extract of four edible medicinal plants in Rivers State using standard procedures. The four medicinal plants investigated include Xanthosoma mafaffa scott, Chysophyllum albidum G. Don, Annona muricata L. and Lagenaria breviflora. The phytochemical analysis gave the following values: tannin (0.08, 0.05, 0.25 and 1.00 mg/kg), phenol (0.93, 0.23, 1.24 and 3.10mg/kg), terpenoid (1.36, 3.01, 5.05 and 3.10%), alkaloid (3.25, 0.23, 0.67 and 1.80 mg/kg), flavonoid (1.87, 6.47, 4.04 and 13.00 mg/kg) and saponin (2.69, 12.63, 2.24 and 12.00%) respectively. The proximate result showed the content (%) of moisture as (83.35, 56.22, 60.57 and 51.84%), Ash (0.63, 3.66, 3.42 and 1.40%), fat (0.31, 3.82, 1.02 and 19.63%), Crude protein (2.04, 6.73, 5.22 and 3.90%), carbohydrate (11.99, 19.59, 14.03 and 13.99%) and Crude fibre (8.34, 9.97, 15.74 and 9.24%). The result showed that these plants could be used in diets to improve human health and pharmaceutical industries. Copyright@ International Science Community Association
