The study was carried out to evaluate the phytochemical and fatty acid compositions of two species of Ocimum. The result of the phytochemicals analysis revealed higher concentration of phytochemical in Ocimum gratissimum such as the presence of alkaloid (5.23%,), saponin (5.23%), flavonoid (11.07%), phenol (1.04%), tannin (4.13%), phytate (124.4%) and oxalate (59.9%) compared to Ocimum basilicum. Fatty acid analysis showed that essential oil was significantly high in Ocimum gratissimum. linoleic (41.7%), docosahexaenoic (0/95%) and arachidonic acid (0.77%) was more concentrated in O. gratissimum compared to O. basilicum, the concentration of α-linoleic acid is the same for both species, non-essential oil was higher in O. gratissimum except palmitic acid. It revealed that myristic (1.89%) margaric (0.77%), stearic (6.35%), arachidic (3.82%), pentadecanoic acid (0.98%), palmitoleic trans acid (1.52%) and behenic (4.42%) were high in O. gratissimum than O. basilicum. The result of the analyzed Ocimum showed that there were significant concentrations of phytochemicals and fatty acid in Ocimum gratissimum compared to Ocimum basilicum making the nutritional contents useful for valuable healthy ingredient to improve the deficiency of these phytochemicals and essential oil in human diet.
