The proximate analysis of A. elongata indicated that the plant possessed sufficient quantities of moisture content, fibre content, total ash, acid soluble ash and water soluble ash, loss on drying, alcohol soluble extractive, water soluble extractive, chlorophyll, carotenoid, protein, carbohydrate, ascorbic acid, phenols and flavonoids. The preliminary phytochemical analysis showed the presence of alkaloids, steroids, terpenoids, saponines, Flavonoids, Glycosides, Tannin, Coumarin and phenol in the methanolic root, stem and leaves extract of A. elongata.
