The nutritional compositions of selected green leafy vegetables obtained from major towns in Oyo State, Nigeria, (March and April) were determined using standard analytical methods for proximate analysis. The following nutrients in percentage were determined; moisture contents, ash, fat, crude fibre and crude protein. The green leafy vegetable used are Talium triangulare, Amaranthus hybridus, Launaena taraxacifolia Ocimum gratissimum, Celosia argentea, Cucuribita maxima, Abelimoschus esculentus, Solanum macrocarpon, Vernonia  amygdalina  and Sesamum indicum. All nutrients were present in appreciable quantities. Moisture contents ranged from 5.33 ± 0.06% - 8.33 ± 0.06%, ash (23.07 ± 0.06% - 61.27 ± 0.06%), fat (1.13 ± 0.06% - 3.37 ± 0.06%), crude fibre (2.43 ± 0.12% - 22.03 ± 0.06%), and crude protein (18.50 ± 0.10% - 55.23 ± 0.06%). The functional properties of vegetables were close in term of high protein level indicating that they are more nutritious. Also, the level of their ash content showed that the vegetables are very rich in essential minerals for healthy life when compared with one another and recommended dietary allowance (RDA). Thus, there is a need for farmers in the area to engage in dry season vegetable production so as to ensure availability of leafy vegetables throughout the year.

The nutritional composition of vegetables is adversely affected by the method of processing for storage or preservation. This study was designed to determine the effect of blanching, boiling, and drying on the nutritional composition of selected vegetables using standard analytical methods. Proximate analysis was carried out on the fresh and processed leaf samples. Results obtained revealed that all the vegetables analyzed contained an appreciable amount of moisture, ash, protein, fiber, carbohydrate, β-carotene, and vitamins. Results also showed that all the processing methods employed significantly reduced (p < 0.05) the nutritional compositions of the vegetables studied. However, drying under the shade retained more nutrients compared to the other processing methods. Drying significantly increased (p < 0.05) the carbohydrate and protein contents of all the leaves (79.92 % & 7.51 % respectively in Basella alba, 66.74 % & 12.09 % respectively in Amaranthus hybridus, 82.56 % & 10.07 % respectively in Celosia argentea, 70.77 % & 13.05 % respectively in Gnetum africanum and 89.12 % & 4.70 % respectively in Talinum triangulare) compared to blanching, boiling and the control. Thus, from the three processing methods studied, drying was the most effective processing method that retained nutrients and is, therefore, a good preservation method for the vegetables.

Traditional leafy vegetables are those plants leaves or aerial parts have been integrated in a community’s culture for use as food over a long span of time. These vegetables are highly recommended due to their relatively high nutritional value compared to the introduced varieties, and are also important in food security. Qualitative phytochemical screening, using standard laboratory procedure, was carried out for alkaloids, saponins, cardenolides, flavonoids and polyphenols on traditional leafy vegetables consumed amongst the Luo, an agro-pastoral community living along the shores of lake Victoria, Western Kenya. The vegetables included: Amaranthus hybridus L. (subsp.hybridus), Asystasia mysorensis T. Anderson, Coccinia grandis (L) Voigt, Crotalaria ochroleuca (Kotschy) Polhill, Cucurbita maxima Duchesne ex Lam, Portulaca quadrifida L., Sesamum calycimum Welw. var. angustifolium (Oliv.) Ihlenf. and Siedenst., Senna occidentalis L. and Sida acuta Burm. F. All the vegetables were found to contain polyphenols and flavanoids while other classes of phytochemicals varied from species to species. Brine shrimp lethality tests revealed that S. calycimum var. angustifolium (LC50 84.8 g/ml), S. occidentalis (LC50 99.5 g/ml), S. acuta (LC50 99.4 g/ml), C. grandis (LC50 100.6 g/ml) and A. mysorensis (LC50 207.7 g/ml) exhibited marked levels of toxicity. C. ochroleuca (Sunnhemp) contained all the five classes of phytochemicals, but proved less toxic (LC50 4511.3 g/ml). This vegetable is highly utilized in Nyang’oma, and seventy per cent of the respondents consume this species. Though A. hybridus (African spinach, or Amaranth) was found to be the least toxic (LC50 6233.6 g/ml) and this vegetable is recommended for consumption. From the results, five vegetables contain possible agents that can cause acute or chronic toxicities when consumed in large quantities or over a long period of time. Hence some vegetables should be consumed with great care. Further studies are recommended to determine which of the phytochemicals are lethal to mammals, especially human beings.

This study was conducted to evaluate the growth response of three leafy vegetables (Celosia argentea, Amaranthus cruentus and Amaranthus hypochodriacus) to the leaf extract of Vitellaria paradoxa. Forty-five (45) experimental plastic containers were filled with 5 kg of loamy soil each and randomly allocated to the following regimes: control, 20 g, 40 g, 60 g and 80 g of powdered leaves of V. paradoxa, in three (3) replicates for each test crop respectively. It was observed that the response of the three leafy vegetables, grown within different composition of V. paradoxa leaves, are concentration dependent with respect to the studied growth parameters (plant height, leaf number, leaf area, stem girth). This indicated that V. paradoxa has allelopathic potential on the studied vegetables and therefore it could be used for natural weed control.

Dietary intake of a variety of vegetables is very important for disease prevention and may help in the treatment of certain maladies. Experiments were conducted to evaluate yield and the content of antioxidants and phenolics of vegetable Amaranth (Amaranthus hybridus), Celosia (Celosia argentea), Gboma (Solanum macrocarpon), and Long Bean (Vigna unguiculata) in response to poultry litter (PL) and a hydrolyzed fish fertilizer [Megabloom (MB)]. The experiments were conducted as a randomized complete block design with a four × three factorial treatment and four replications. The treatments were applied based on soil test recommendations in a single band 15 to 20 cm away from the plants 1 week after transplanting. Plants were harvested sequentially during the season as foliage and fruits became physiologically mature and once over at the end of the season. Species were analyzed for vitamin C content, total phenolics, and β-carotene content as well as antioxidant capacity. Organic amendments did not significantly influence biomass production, whereas species impacted fresh and dry biomass. Amaranth, Celosia, and Long Bean produced greater fresh and dry biomass than did Gboma. Vitamin C content was highest among Amaranth and Celosia plants receiving nitrogen–phosphorus–potassium (NPK) compared with the other two treatments, whereas that of Gboma was higher among plants receiving MB.

The present study investigated the effect of processing on anti-nutritional factors of thirteen traditional leafy vegetables collected in KwaZulu-Natal, South Africa. The purpose of this study was to determine whether processing reduced anti-nutrient levels of the species. Three boiling parameters were used with a ratio of 1:4 vegetable to water for a time period of 0, 5 and 15 min. The vegetables studied were: Amaranthus dubius, Amaranthus hybridus, Asystasia gangetica, Bidens pilosa, Ceratotheca triloba, Chenopodium album, Emex australis, Galinsoga parviflora, Guilleminea densa, Momordica balsamina, Oxygonum sinuatum, Physalis viscosa and Solanum nigrum. From this study, it was determined that non processed samples contained anti-nutrients such as tannins (0.01–0.14 mg/ml), phytic acid (0.002–0.059 mg/ml), alkaloids (3.6–11%), oxalic acid (85.2–1079.3 mg/ml) and cyanogenic glycoside (17–33 mg/100g). Solanum nigrum was the highest in tannin content (0.14 mg/ml).Ceratotheca triloba was the highest in phytic acid content (0.06 mg/ml). Momordica balsamina (11.1%) and Physalis viscosa (10.3%) ranked the highest overall in alkaloid content. Ceratotheca triloba (1079.3 mg/ml), Amaranthus hybridus (796 mg/ml) and Oxygonum sinuatum (673.9 mg/ml) were the highest in oxalic acid. Asystasia gangetica (33.3 mg/g), Ceratotheca triloba (32.6 mg/g), Momordica balsamina (32.5 mg/g), Physalis viscosa (32.3 mg/g) and Solanum nigrum (32.2 mg/g) were the highest in cyanogenic glycoside. All anti-nutrients were reduced significantly through boiling in all the species. The results of this study provide evidence that the local traditional vegetables upon which the population is so reliant upon, are important contributors in micronutrient malnutrition in developing countries and can be eliminated through common boiling methods for a minimum of 5 and maximum of 15 minutes.

In Southern Angola, numerous non-woody forest products are sold at local markets, namely in Lubango (Huíla Province). Such is the case of herbaceous wild plants, locally known as lombi, which are sold fresh throughout the year and cooked as a vegetable. Although these wild leafy vegetables are commercialized and widely used in local food, there is still a lack of scientific knowledge about their properties. Thus, this study aimed to identify and characterize the species sold, and to determine their nutritional and functional properties. Our results revealed that three species—Amaranthus hybridus, Bidens pilosa, and Galinsoga parviflora—are usually sold at Lubango markets and consumed by local populations. These are annual exotic plants, native to Southern America, and usually occur spontaneously in croplands or disturbed areas, but can also be cultivated, particularly A. hybridus. Physico-chemical analyses of lombi species and mixtures sold at the markets included measurements of moisture, protein, lipid, and mineral content, as well as total phenolic content, antioxidant activity, and levels of heavy metal contaminants. The results revealed that lombi contain a significant amount of protein (20–28 g/100 g, dry basis), high values of macronutrients and micronutrients, as well as of phenolic compounds (10–40 mg GAE/g) and a good antioxidant capacity. Given the availability of lombi throughout the year, our study demonstrated the importance of wild edible plants in Angola, both as a valuable natural resources and as a complementary food sources, as well as additional sources of income for many families.

Purpose The purpose of this study is to assess the effects of two green leafy vegetables (Gongronema latifolium and Celosia argentea) on the hepatic biomarkers [Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST)], cardiac biomarkers [Creatine Kinase (CK) and Lactate Dehydrogenase (LDH)] and histopathology of the heart of high-fat diet-induced hyperlipidemic rats, with the aim of evaluating the vegetables as functional foods. Design/methodology/approach Experimental diets consisted of Control Diet (CD), High-Fat Diet (HFD), High-Fat Diet with Blanched Celosia argentea (HCB), High-Fat Diet with Unblanched Celosia argentea (HCU), High-Fat diet with Blanched Gongronema latifolium (HGB) and High-Fat Diet with Unblanched Gongronema latifolium (HGU). Seventy-five albino male rats (weighing 180–200 g) were used. The animals were divided into 15 groups of five albino rats each. Animals in Groups 1, 2 and 3 were fed with CD, HFD only and HFD with Atorvastin (5 mg/kg b.w), respectively. Animals in Groups 4, 5 and 6 were fed with 5, 10 and 15% HCB, respectively. Animals in Groups 7, 8 and 9 were fed with 5, 10 and 15% HCU, respectively, whereas animals in Groups 10, 11 and 12 were fed with 5, 10 and 15% HGB, respectively, and animals in Groups 13, 14 and 15 were fed with 5, 10 and 15% diet-inclusion of HGU, respectively. Findings The incorporation of the vegetal matter into the diet brought about a significant reduction (p = 0.05) in the activities of ALT, AST, CK and LDH when compared with HFD. However, the histological examination showed no pathological lesion, only at 15% inclusion of the vegetables. Originality/value The paper established that the incorporation of Celosia argentea and Gongronema latifolium into diet, most especially at 15% inclusion, may serve as functional food in the management of hyperlipidemia and associated complications.
