چکیده
The phytochemical and proximate analyses of Psidium guajava leaves were determined using the methods of association of official analytical chemists (A.O.A.C). The quantitative analyses showed the concentrations (mg/100g) of the phytochemical constituents as flavonoids (0.40 ± 0.02), tannins (0.55 ± 0.01), glycosides (3.76 ± 0.08), alkaloids (0.04 ± 0.00), saponins (3.01 ± 0.01), phenols (0.28 ± 0.00) and steroids (0.09 ±0.00). The proximate composition (%) of moisture, ash, fat, fibre, protein and carbohydrate recorded 10.74 ± 0.08, 4.35± 0.21, 1.37 ± 0.36, 10.37 ± 0.05, 18.64 ± 0.05 and 54.53 ± 0.25 respectively. The plant showed higher levels of carbohydrate, glycosides and saponins, moderate levels of tannins, flavonoids, protein, moisture and crude fibre with relatively low levels of alkaloids, phenols, steroids, ash, and fat.
