Abstract:

Most vegetables, including Vernonia amygdalina (bitter leaf) and Ocimum gratissimum (scent leaf), play a vital role in supporting the healthy development of human organs. This study compared the nutritional values of these two vegetables through mineral and proximate analyses. Fresh samples of bitter leaf (Vernonia amygdalina) and scent leaf (Ocimum gratissimum) were obtained from a personal farm in Edjeba, located in the Warri South Local Government Area of Delta State. The vegetables were air-dried at room temperature, ground, and sieved using a 2mm sieve, then stored in sterile Ziploc bags
