“…The presence of phyto-nutrients such as flavonoids, saponins, alkaloids and tannins in Gongronema latifolium leaves is an indication that the plant possesses the ability to scavenge for free radicals, thus health promoting in action 15 . The phytochemicals present in this study is similar to previously published phytochemicals in other plant leaves [16][17][18][19].…”

Background study: Gongronema latifolium is primarily used as spice and vegetable as well as a herb in traditional medicine in the treatment of malaria, diabetes and hypertension. This study is aimed at providing in vitro laboratory knowledge on Gongronema latifolium leaves. Methods: Minerals were analyzed using Atomic Absorption Spectrophotometer while phyto-nutrients were screened using standard laboratory procedures. 2,2-diphenyl-1-picrylhydrazyl (DPPH)-radical scavenging and reducing power activities were determined spectrophotometrically. Results: Results showed that Gongronema latifolium leaves contains flavonoids, tannins, saponins, alkaloids, terpenoids etc as well as minerals such as calcium (333.40mg/100g), magnesium (38.90mg/100g), potassium (83.69mg/100g), sodium (31.02mg/100g), phosphate (51.13mg/100g), iron (4.88mg/100g), zinc (2.19mg/100g) and chromium (0.98mg/100g). DPPH-radical scavenging and reducing power activities of Gongronema latifolium leaves showed the plant be concentration dependent as free radical scavenging activity increases as concentration increases from 0.2-1.0mg/ml. Conclusion: The presence of bioactive agents, minerals and free radical scavenging potentials of Gongronema latifolium leaves makes it a beneficial medicinal plant.

“…In this study proximate composition analysis showed that dry matter (94.33%), crude protein (30.05%), crude fat (9.85%) and ash (13.35%) were higher than the proximate analysis of fluted pumpkin (Telfairia occidentalis) pod determined by Akwukwaegbu et al (2016) Usunobun and Egharebva (2014) findings in phytochemical analysis of T. occidentalis aqueous leaf extract. The disparity in the values obtained in this study and other authors could be attributed to the plant species, method of harvesting, handling, storage, environmental and climatic factors of where the plants are located.…”

Nutrient utilization is determined by absorbable and digestible nutrients in fish feeds. The aim of the experiment was to investigate the effects of unprocessed dried leaves of Telfairia occidentalis (UDLTO) and Mucuna utilis (UDLMU) on histology and growth of C. gariepinus. Sixteen weeks feeding trial experiment was conducted using two hundred and twenty-five Clarias gariepinus with a mean weight 4.16±0.09g. Fish meal was replaced with 0, 25, 50, 75 and 100% levels of UDLMU and UDLTO. Growth parameters and histological examinations were carried out according to standard procedures. Mean Weight Gain (MWG) of 0% (15.8g) was significantly higher P0.05 compared to other treatments. Specific Growth Rate (SGR) of 0% (0.64) varied significantly P0.05 than other levels of inclusions. Kidneys of fish fed 25 and 50% graded levels showed patchy vacuolar degeneration of the renal tubules. Gills of fish fed 75 and 100% graded levels showed diffuse capillaries and moderate congestion of lamellar in the gills. Tissue examinations of fish fed 50, 75 and 100% graded levels exhibited clinical signs of moderate atrophy and vacuolation of hepatocytes and diffuse hepatocellular swelling and degeneration in the liver. Histological investigations revealed fragmentation and atrophy of muscle fibre in fish fed 75% graded level. There was moderate atrophy of villi of the intestine of fish fed 100% graded level. It is apparent that the increased levels of UDLMU and UDLTO could not support good growth as presumed due to the presence of anti-nutritional factors in the leaves.Keywords: Nutrient utilization, Fish meal, Inclusions, standard procedures, Clinical signs

“…The eggplant contains minerals such as; calcium DUJOPAS 9 (1a): 160-167, 2023 162 (256.60mg/100g), copper (0.62mg/100g), while manganese is absent or relatively low. Other minerals present include; magnesium (81.69mg/100g), potassium (87.22mg/100g), sodium (32.51mg/100g), irons (31.41mg/100g), and zinc (1.41mg/100g) as reported by Usunobun and Igwe (2016). African eggplant fruits have relatively higher carbohydrate of (7.2 g/100g), fibers (2.0g/100g) and considerable amount of beta carotene (0.35 mg/100g), ascorbic acid (8 mg/100g), riboflavin (0.06 mg/100g) and thiamin (0.07 mg/100g) (Majubwa, et al, 2015;Theodosy, et al, 2014).…”

Fruits and vegetables are considered as good source of functional foods due to their health benefits and nutritional content. Dietary constituents of fruits and vegetable are commonly available and has significant application in management of chronic diseases such as; coronary heart disease, stroke, cancer and diabetes, many medicinal purposes, control of excess weight and obesity due to high fiber content present. Many phenolic compounds had been identified in garden eggplant such as; catechin, rutin, naringin, naringenin, syringic acid, chlorogenic acid, caffeic acid, p-coumaric acid, sinapic acid and anthocyanin. Health-conscious consumers generally focus on the antioxidant capacity, and the phenolic content, vitamins, carotenoids and phytochemicals. All varieties of garden egg vary in polyphenol endowed with antioxidant activity. Polyphenolic compounds and antioxidant activity in eggplants which depend on the cultivar, maturity stage and parts of the fruit. Growing conditions are also reported to significantly affect the phenolic contents. This review discussed the polyphenolic contents and antioxidant activities of different eggplant cultivars. Priority was given to green, white and dark-purple cultivars which are commonly grown in Nigeria. White and green eggplants possess higher phenolic contents when compared with dark purple eggplant which possesses higher antioxidant capacity. They contain about 92% water, 5% protein, copper (0.62mg/100g), magnesium (81.69mg/100g), potassium (87.22mg/100g), sodium (32.51mg/100g), irons (31.41mg/100g), zinc (1.41mg/100g), carbohydrate (7.2 g/100g), fibers (2.0g/100g), calcium (28 mg/100g), iron (1.5 mg/100g) and considerable amount of beta carotene (0.35 mg/100g), ascorbic acid (8 mg/100g), riboflavin (0.06 mg/100g) and thiamin (0.07 mg/100g). The species of African eggplant have nutritional and therapeutic values and can be used in the development of functional foods and these bioactive compounds are responsible for high functions of eggplants and provide antibacterial, anti-inflammatory, anti-allergic, hepatoprotective, antithrombotic, antiviral, anti-carcinogenic and vasodilatory properties in humans.
