Proximate Analysis, Mineral Content, Amino Acid Composition and Functional Properties of Vernonia amygdalina Vegetable Leaf Protein Concentrates

Abstract

Freshly harvested Vernonia amygdalina green vegetable was authenticated and processed for its vegetable leaf protein concentrates with a view to evaluate its proximate constituents, amino acid content and mineral composition. Proximate analysis was determined using standard analytical technique. The nutrient composition of the protein concentrates revealed the moisture content (66.45±0.07), Crude fat (9.20 ±0.85), Crude fibre (10.46±1.05), Crude protein (44.28 ±2.43), ash (12.48± 0.24) and Carbohydrate (23.58±3.4). The mineral content of the sample indicated that Ca, Mg, K, and Na are the most abundant minerals with the following values Na;57.5±0.34,Ca;151.6±1.40, K; 61.5±0.38, Mg; 96.5±0.96, other minerals that were present in the sample in trace concentration are Fe(2.3 ± 0.42), Zn (1.11± 0.11), Mn (0.1± 0.14), Cu (0.1 ± 0.73), Pb (0.1± 0.63),while Selenium were not detected in the sample indicating that the leaf concentrate is fit for dietary consumption. The amino acid profile reveals favourable nutritional balance with the presence of essential and non-essential amino acid except that tryptophan which was believed to be predominant in animal protein was not detected.

Role of bitter leaf (Vernonia amygdalina) extract in prevention of renal toxicity induced by crude petroleum contaminated diets in rats

“…An insight to the justification of increased GSH levels in treated rats relative to untreated rats has been earlier reported in the study of Huang et al [46] who stated that there is an increase in the levels of tissue glutathione during early stages of tissue regeneration. It is important to note that matured bitter leaf has been reported to have a level of glutamic acid, one of the amino acids essential for the synthesis of glutathione [47], [48]. GSH has also been identified as a significant factor in the maintenance of the concentrations of exogenous antioxidants such as vitamins C and E in their reduced (active) forms.…”

Carcass Evaluation and Blood Metabolites of Finishing Broiler Chickens Fed Bitterleaf (Vernonia Amygdalina Del.) Meal as Feed Additive in a Tropical Environment

“…The results indicated that bitter leaf meal had a dry matter of 92.44%. The crude protein content was 27.40%, which is higher than the value reported byTsado et al (2015), but lower than the crude protein content reported byAsaolu et al (2012) andSodamade (2013). The ash content of 9.73% was lower than that reported byUdochukwu et al (2015) but higher than the value reported by Tsado et al (2015), and Asaolu et al (2012).…”

Prophylaxis of malaria by Artemisia infusions: The key role of lysine

“…All values lower than for Artemisia. 16 As noted previously, Artemisia plants are rich in both lysine and zinc. In malaria infections it was noticed that there is a strong synergy between zinc and arginine in the inhibition of hemozoin (Mutaz Akkawi, Al Quds University, Palestine, personal communication).…”
