“…Since it is known that the bacteria have an outer phospholipid membrane that makes their cell wall hardly penetrable by antimicrobial agents [28]. In a recent work, we have demonstrated that these four wild fruits are rich sources of protein, minerals, and vitamins [15]. So, these molecules could reduce the effect of extracts against bacteria [29].…”

“…hold an important place. Although their nutritional virtues have often been investigated throughout the continent [15][16][17][18], very little scientific data exist on their antibacterial properties. Therefore, further investigations are needed in order to have a better understanding of their therapeutic virtues for the management of certain diseases related to the consumption of unhealthy foods such as salmonellosis, cholera and hepatitis A.…”

Aims: This study aimed to assess the in vitro antibacterial effects of extracts from four wild food fruits: Balanites aegyptiaca, Saba senegalensis, Ziziphus mauritiana, and Raphia sudanica. Place and Duration of Study: The samples of plant material were collected at Banamba and Sikasso, Mali between January and May 2018. The bacterial strains were collected at Research Centre for Biological Food and Nutritional Sciences (CRSBAN), University Professor Joseph Ki-Zerbo; Ouagadougou, Burkina Faso. The experimental parts were also carried out at CRSBAN from October 2019 to January 2020. Methodology: The fruit extracts were screened for antibacterial activity against Escherichia coli, Salmonella typhi, S. aureus, B. cereus, and L. monocytogenes strains. The diameters of the inhibition zones (ID), the minimum inhibitory concentrations (MIC) as well as the minimum bactericidal concentrations (MBC) were evaluated using agar diffusion method. Results: The findings revealed that these parameters have varied as a function of fruit species and/or their zones of provenances. All fruit extracts showed significant growth reducing effect against all the tested bacteria. The extracts from R. sudanica have exhibited the strongest growth-inhibiting activity specifically against E. coli (ID = 15.33±0.58 mm) and Salmonella typhi (ID = 18.00±1.00 mm) with lower MIC (from 2.08±1.44 to 5.83±1.44 mg/mL). Moreover, the MBC/MIC ratios revealed that the extracts from the studied fruits possess mainly bacteriostatic effects towards the tested strains. Conclusion: These findings support local therapeutics properties attributed to these fruits. They also demonstrate that, in addition to their nutritional values, these edible fruits could be used for developing antibiotics to treat infectious diseases and food poisoning.

“…In a recent study, we showed the nutritional and functional values of the fruits of these two species [ 9 ] as linked to their high content of nutrients and bioactive compounds such as proteins, polyunsaturated fatty acids, sterols, polysaccharides, vitamins, minerals, phenolic compounds, volatile compounds, and carotenoids [ 8 , 10 ]. It is known that these bioactive compounds play vital roles in human nutrition and the human health system due to their capacity for scavenging oxidative agents, stimulating the immune system, affecting hormone metabolism, and antibacterial and antiviral effects [ 1 , 11 , 12 ].…”

Currently, microencapsulation has become a viable method of nutrient delivery for the food industry. This work microencapsulated the bioactive compounds extracted from two neglected species (Balanites aegyptiaca and Ziziphus mauritiana) by freeze-drying. A combination of wall materials (whey protein and pectin; soy protein and maltodextrin) was chosen to prepare the microcapsules. The phytochemical and physicochemical characterization of the microcapsules was then carried out. The encapsulation yield ranged from 82.77% to 96.05% for Balanites and Ziziphus, respectively, whereas the efficiency was 76.18 ± 1.39% and 80.93 ± 1.71%. The stimulated in vitro gastrointestinal test showed that encapsulation increased the bioavailability of the bioactive compounds. The total carotenoids were the most bioavailable compounds with 85.89 ± 0.06% for Ziziphus and 70.46 ± 1.10% for Balanites, followed by total flavonoids for Zizyphus with 63.27 ± 1.56%. Furthermore, regardless of species or wavelengths, the HPLC analysis resulted in the identification of 17 bioactive metabolites. The predominant one was epicatechin, whose level ranged from 231.52 ± 5.06 to 250.99 ± 3.72 mg/100 g DW in Ziziphus and 91.80 ± 3.85 to 116.40 ± 4.09 mg/100 g DW in Balanites. In estimating the enzyme inhibition and antioxidant power, both studied fruits showed antidiabetic, inflammatory, and antioxidant effects. These findings suggest that natural bioactive compounds are abundant in the fruits of Z. mauritiana and B. aegyptiaca and could be a valuable source for the food and pharmaceutical industries.
