Abstract

Comparative phytochemical and proximate evaluation of leaf extracts Gongronema latifolium and Ocimum gratissimum was carried out using standard laboratory procedures. The result of the preliminary phytochemical screening of the leaf extracts of Ocimum gratissimum and Gongronema latifolia revealed that alkaloid was deeply present in the leaf extract of O. gratissimum; while saponin was deeply present in the leaf extract of G. latifolia. The result also revealed the presence of tannin, saponin, flavonoid, cardiac glycoside and phenol in the leaf extracts of O. gratissimum. The result of the mean phytochemical composition of the leaf extracts of Ocimum gratissimum and Gongronema latifolia revealed higher composition of alkaloid (1.89±0.014mg/100mg) in O. gratissimum. The result also revealed high composition of flavonoid (1.89±0.014mg/100mg) in the leaf extract of O. gratissimum. The leaf extract of G. latifolia gave higher composition of saponin (2.11±0.021mg/100mg) and alkaloid (2.02±0.014mg/100mg). The leaf extract of O. gratissimum had the least composition of saponin (0.65±0.028mg/100mg); while G. latifolia had the least composition of tannin (0.70±0.014mg/100mg). The result of the percentage proximate composition of the leaf extracts of Ocimum gr revealed higher composition of carbohydrate (44.12±0.318%) in the leaf extract of O. gratissimum; while the leaf extract of G. latifolia had higher composition of protein (33.15±0.078%). This study justifies the use of O. gratissimum and G. latifolia leaves as vegetables and in treatment of certain diseases such as diabetes, hypercholesterolemia and liver problems. The results of the study demonstrate that O. gratissimum and G. latifolia may be consumed daily for health benefits.
