Musa paradisiacal and Brassica oleracea are medicinal plants cultivated in tropical and subtropical nations, and widely used as food and folklore medicine around the globe. But, the basis for its use in the prevention and treatment of diseases in the various parts of the world has not been properly elucidated. Samples of both plants were analyzed and the compositions of the phytochemistry, proximate, mineral and vitamin were revealed. The phytochemistry indicated that M.paradisiaca fruit extract contain flavonoids and alkaloids in large amount, tannin, oxalate, phytates in moderate amount and saponin, phenols and glycosides in small amount, also B. oleracea contain alkaloids and glycosides in large amount, tannin, oxalate, flavonoids and phytic acids in moderate amount and saponin in small amount. Both plants also contain moisture, ash, protein, carbohydrate, fiber, total and saturated fats in variable amounts, and also contain some useful vitamins and minerals. There was a significant amount of ascorbic acids ( M. paradisiaca 9.33 ± 0.2 and B. oleracea 38.1 ± 0.2 ) and K ( M. paradisiaca 401.1 ± 0.3 and B. oleracea 260.2 ± 0.2 ), the high K and low Na may be the reason behind its use in hypertension, stroke, arrhythmia and cancer prevention. These phytochemicals, proximates, minerals and vitamins embedded in these plants has justified its forkloric uses in many cultures.
