Abstract
Amaranthus rectroflexus (AmE) and Gnetum africanum (GnA) is the most popular green leafy vegetable in Gabon and is gaining equal popularity as a delicious food leaf in other African countries such as Cameroon, Nigeria, Congo and Angola. The purpose of this study was to assess the impact of these plants in modulating urea, creatinine and plasma electrolytes. 50 mg/kg of aqueous extract were given to rats in the experimental groups for two week, while rats in the control group received an appropriate volume of water. Urea creatinine, and Plasma electrolytes were measured by spectrophotometric method. Chronic oral administration for two week of 50 mg/kg of AmE and GnA aqueous extracts significantly decreased plasma sodium concentration benefit to potassium (P 0.05) in weight, blood glucose, creatinine and urea plasma concentration.
Highlights
Plants, green leafy vegetables, serve as a major dietary reservoir of the essential PUFAs, dietary fiber, antioxidants and other bioactive compounds that exert cardioprotective biological mechanisms (Veer et al, 2000; Kris-Etherton et al, 2000; Hu, 2003; Slavin, 2003)

Summary
Green leafy vegetables, serve as a major dietary reservoir of the essential PUFAs, dietary fiber, antioxidants and other bioactive compounds that exert cardioprotective biological mechanisms (Veer et al, 2000; Kris-Etherton et al, 2000; Hu, 2003; Slavin, 2003). Amaranthus extrafolus (AmE) and Gnetum africanum (GnA) are the most popularity plant food in Gabon and is gaining equal popularity in other African countries such as Cameroon, Nigeria, Congo and Angola (Eyo & Abel, 1983). The leaves are nearly 15 cm long on large individuals, the ones higher on the stem having a lance shape and those lower on the plant diamond or oval in shape (Figure 1A). The seed of GnA is oval in shape and small in size, about 0.5 cm in diameter. They are greenish in color when and randomly from a thick bush around the rain unripe and reddish when ripe (Figure 1B)
