“…Fruits are an important source of nutrition with diverse physiological functions and health benefits [ 36 ]. Furthermore, Schreckenberg et al (2006) [ 65 ], Aremu et al (2019) [ 29 ], and Omotayo and Aremu [ 66 ] indicated that the potential of indigenous fruits is often not recognized either at national or international level as an efficient and affordable nutrient deficiency reduction strategy. In addition, indigenous and naturalized fruits usually contribute to food and nutrition security, health, and income generation of rural communities [ 67 ].…”

“…According to Department of Agriculture Forestry and Fisheries [ 28 ], “South Africa’s indigenous food crops refer to food crops that have their origin in South Africa. Added to these crops are those that were introduced into the country and are now recognized as naturalized or traditional crops of South Africa.” On this basis, we compiled a list of 31 indigenous and naturalized plants recognized as important and popular based on information from different sources such as the Department of Agriculture Forestry and Fisheries [ 28 ], Mashile et al (2019) [ 8 ], Aremu et al (2019) [ 29 ], van Wyk [ 17 ], and the government agency website (agribook.co.za/horticulture/indigenous-food-crops). In addition, a photo album of the 31 selected plants was compiled to aid visual recognition during the survey; the pictures were derived from the aforementioned literature and where absent, we consulted reliable websites.…”

Globally, a substantial proportion of existing indigenous and naturalized foods are often neglected thereby narrowing the food-base available to humans. The current study explored the use and contribution of indigenous and naturalized plants to the households’ food-pool among 12 communities in the North West Province of South Africa. An ethnobotanical survey was conducted among 133 rural households across the 12 selected communities from the four district municipalities in North West Province, South Africa. We analyzed the utilization patterns for 31 selected indigenous and naturalized plants (grains, fruits, and vegetables) among the 133 households using two ethnobotanical indices. In reference to the checklist of 31 plants, the sampled households utilize approximately 94% (29) as staple foods, beverages, fruits and fodder. Sorghum bicolor, Vigna unguiculata, Amaranthus sp., Sclerocarya birrea, Persea americana, and Mimusops zeyheri were among the top-six plants based on the Relative Frequency of Citation (RFC, 40–83%). In terms of the different crop-types, Sorghum bicolor (grain), Amaranthus sp. (vegetable), and Sclerocarya birrea (fruit) were the top-ranked plants based on the Species Popularity Index (SPI, 0.53–0.83) among the participants. Overall, there is a need for a renaissance of indigenous and naturalized plants, which has the potential to encourage rural farmers to further embrace the cultivation of these plants on a larger scale so as to enhance food security in the rural communities.

The diverse range of indigenous fruit trees in Africa is a source of untapped potential for food and nutrition security. Here, we review information on 10 indigenous fruit trees that are considered to be underutilized and explore their occurrence, distribution, nutritional components, phytochemicals, and medicinal potentials, as well as their associated challenges and prospects. The indigenous fruit trees, which occur across different ecological zones in Africa, are rich sources of vitamins, minerals, protein, and valuable phytochemicals. They also have recognized medicinal value and used as diverse therapeutic remedies by many ethnic groups in Africa. The key challenges to fruit tree sustainability include indiscriminate and illegal logging, low accessibility, and low acceptability, as well as inadequate research on their cultivation. We proposed a scheme to increase the value chain of underutilized fruit trees, which can contribute to the livelihoods of smallholder farmers and other stakeholders mainly through income generation. In addition to the concerted efforts of multidisciplinary research teams encompassing plant breeders, botanists, molecular biologists, food scientists, and horticulturists, there is an urgent need for governments and other international stakeholders to provide incentives and encourage the domestication, commercialization, and agro‐processing of underutilized fruit trees for future economic prosperity of Africa.

“…A previous study also showed an antifungal activity of D. caffra -derived fruit juice against Microsporum canis , Malassezia furfur and Candida albicans 14 . Furthermore, antibacterial activities were observed against Staphylococcus aureus 4 . Even though these scientific reports have highlighted the antimicrobial activities of D. caffra , studies to evaluate the potential therapeutic use of D. caffra fruit would extensively be necessary.…”

Secondary plant metabolites remain one of the key sources of therapeutic agents despite the development of new approaches for the discovery of medicinal drugs. In the current study, chemical analysis, and biological activities of Kei apple (Dovyalis caffra) methanolic extract were evaluated. Chemical analysis was performed using HPLC and GC–MS. Antiviral and anticancer effect were assessed using the crystal violet technique and activity against human liver cells (HepG2), respectively. Antibacterial activity was tested with the disc diffusion method. The obtained results showed that chlorogenic acid (2107.96 ± 0.07 µg/g), catechin (168 ± 0.58 µg/g), and gallic acid (15.66 ± 0.02 µg/g) were the main bioactive compounds identified by HPLC techniques. While, compounds containing furan moieties, as well as levoglucosenone, isochiapin B, dotriacontane, 7-nonynoic acid and tert-hexadecanethiol, with different biological activities were identified by GC–MS. Additionally, inhibition of 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) scavenging was 79.25% at 2000 µg/mL, indicating its antioxidant activity with IC50 of 728.20 ± 1.04 µg/mL. The tested extract exhibited potential anticancer activity (58.90% toxicity) against HepG2 cells at 1000 µg/mL. Potential bacterial inhibition was observed mainly against Escherichia coli and Proteus vulgaris, followed by Staphylococcus aureus and Bacillus subtilis with a diameter of growth inhibition ranging from 13 to 24 mm. While weak activities were recorded for fungi Candida albicans (10 mm). The extract showed mild antiviral activity against human coronavirus 229E with a selective index (SI) of 10.4, but not against human H3N2 (SI of 0.67). The molecular docking study's energy ratings were in good promise with the experiment documents of antibacterial and antiviral activities. The findings suggest that D. caffra juice extract is a potential candidate for further experiments to assess its use as potential alternative therapeutic agent.
