“…For such, the promotion of berry products for consumption is essential. Therefore, intensive research in breeding for selecting desirable lines and subsequent cultivars for release ensuring the quality of the final product and safety to consumers is mandatory (Yuan, Dinssa, et al., 2020; Yuan, Lyu, et al., 2020).…”

Achieving zero hunger in sub‐Saharan Africa (SSA) without minimizing postharvest losses of agricultural products is impossible. Therefore, a holistic approach is vital to end hunger, simultaneously improving food security, diversity, and livelihoods. This review focuses on the African nightshades (ANS) Solanum spp. contribution to improving food and nutrition security in SSA. Different parts of ANS are utilized as food and medicine; however, pests and diseases hinder ANS utilization. African nightshade is rich in micronutrients such as β‐carotene, vitamins C and E, minerals (iron, calcium, and zinc), and dietary fiber. The leaves contain a high amount of nutrients than the berries. Proper utilization of ANS can contribute to ending hidden hunger, mainly in children and pregnant women. Literature shows that ANS contains antinutritional factors such as oxalate, phytate, nitrate, and alkaloids; however, their quantities are low to cause potential health effects. Several improved varieties with high yields, rich in nutrients, and low alkaloids have been developed in SSA. Various processing and preservation techniques such as cooking, drying, and fermentation are feasible techniques for value addition on ANS in SSA; moreover, most societies are yet to adopt them effectively. Furthermore, promoting value addition and commercialization of ANS is of importance and can create more jobs. Therefore, this review provides an overview of ANS production and challenges that hinder their utilization, possible solutions, and future research suggestions. This review concludes that ANS is an essential nutritious leafy vegetable for improving nutrition and livelihoods in SSA.

“…The daily diet of tropical African countries is often dominated by starchy staples and coarse grains which provide energy but do not support growth, metabolic functioning and immune defense of the individual [ 2 , 7 ]. Indigenous vegetables such as Amaranthus cruentus , Celusia argenta and Corchorus olitorius are the cheapest and most readily available sources of proteins, vitamins, minerals and essential amino acids for many people [ 8 , 9 ]. Vegetables such as Digera arvensis, Solanum nigrum have high nutritional value [ 9 – 12 ].…”

“…Thus, their adequacy in a diet would help increase the supply of some nutrients that might be absent in people's regular diet [ 13 , 14 ]. In Africa, wild edible plants are used as food and hence contribute significantly to the nutritional needs of the people [ 9 , 15 ]. Solanum torvum commonly called turkey berry is one of those wild plants known to be helpful in nutrition.…”

“…Its leaves are eaten as a leafy vegetable and the fruits eaten raw or cooked. Phenolic compounds extracted from different parts of S. torvum exhibited anti-oxidant activity [ 9 , 17 ]. It is also reported that the plant has anti-mycobacterial and cytotoxic activities [ 18 ].…”

The fruits and leaves of Solanum torvum are good sources of nutrients and minerals for the prevention of nutrient deficiencies. However, there is limited information on the effect of boiling on the nutrients, minerals and phytochemicals in the fruits and leaves. This study sought to assess the mineral, macronutrient and phytochemical compositions of fresh and boiled fruits and leaves of S. torvum. Fresh unripe fruit and leaf samples of S. torvum were collected from six communities, boiled, and pulverized for mineral, proximate and phytochemical analyses. The data obtained was subjected to ANOVA and t-test. Solanum torvum was found to contain Fe, Zn, Cu, Mn, Ca, Mg, Na, K, protein, crude fat, carbohydrate, fibre, saponins, tannins, flavanols, terpenoids/steroids and glycosides making it nutritious. The results revealed almost equal concentrations of minerals in fresh and boiled leaves and fruits. A similar observation was made in the case of carbohydrate, crude fat and ash. However, there were significant differences in moisture, protein and crude fibre concentrations in the samples. Phytochemical analysis revealed the presence of saponin, tannin, flavonoids, terpenoids/steroids and glycosides in all leaf samples no matter the treatment. There were no flavonoids and terpenoids/steroids in fruits. Boiling nominally reduced and in a few cases, increased concentration of the nutrient composition but did not have significant effect on the concentration of the macro- and micro- minerals in the fruits and leaves. This study suggests that boiling could affects the concentration of nutrients that could be accessed in fruits and leaves of S. torvum.

Solanum nigrum L. and Solanum torvum Sw. are members of the solanaceae family and it is often used to treat a broad range of infectious disorders that may harm humans. These herbs not only possess beneficial medicinal characteristics, but they also mitigate the potential side effects of some medications. Solanum nigrum L. and Solanum torvum Sw. plants have distinct chemical components included within these chemical compounds are referred to as alkaloids, phenols, flavonoids, saponins, tannins, glycosides. In addition, they possess beneficial therapeutic characteristics such as effectively treat a variety of fever, asthma, toothaches, eczema, reproductive disorders, painful periods and hypertension. As parts of the scope of this study, authors investigated the pharmacological processes carried out by the Solanum nigrum L. and Solanum torvum Sw. plants and developed a list of its pharmalogical application in order to get knowledge of its medicinal components with a variety variety of possible applications.
