The present study focuses on the metabolites content and antiradical, antibacterial activities of the hydroethanolic extract of P. biglobosa husks. Secondary metabolites were identified using staining and/or precipitation tests. The mineral content is determined according to the standard NF EN 14082. The antioxidant activity performed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity, and antibacterial activity strain against three Gram-negative and two Grampositive strains by microdilution for Minimal Inhibitory Concentration. Fruit husks contain tannins, anthocyanins, leuco-anthocyanins, anthraquinones, saponins, reducing compounds, sterols, terpenes, and 1.225% of potassium. The hydroethanolic extract of P. biglobosa fruit husks scavenges the DPPH radical with an EC50 = 64 µg/ml. The extract is more active in one Gram (Pseudomonas aeruginosa and Escherichia coli) with a minimum inhibitory concentration of 1.25 mg/mL than the three Gram + studied. This study showed that P. biglobosa fruit husks extract could be used for its antioxidant and antibacterial activities.

Besides food constituents, such as fibre or beta-carotene, other bioactive plant compounds such as polyphenols have been suggested to contribute to this protective effect. Yellow mombin (Spondias mombin L.) is a tropical fruit with increasing acceptance in both national and international fruit markets. However, it remains a neglected and underused species. Neglected and underutilized species (NUS), also known as minor crops or 'orphan' crops, can help solving some global issues, such as hunger, poverty and adaptation to climate change. In this review, we have highlighted the functional potential of the fruit of Spondias mombin. Particular emphasis has been placed on polytphenols, vitamins and minerals.

(Rubiaceae), commonly call ‘’Noni’’ which is currently used as nutraceuticals in traditional medicine. The results of phytochemical analysis indicated that anthocyanins, anthraquinone, leucoanthocyans, coumarins, as well as flavonoids are presents in the juice extracted from Noni fruits. However cyanogenics derivatives compounds are not detected. Microbiological analysis revealed that Noni juice has a low level of microbial contamination with the absence of pathogens such as Staphylococcus aureus (˂1 ufc/ml). The Noni juice, with the presence of these secondary metabolites, offers a novel approach to the management of therapeutic failures, encountered in the treatment of severe forms of certain pathologies. However, further research and clinical trials are required to fix appropriate doses and combinations to be consumed in specific individual cases.

It is obtained by roasting the different organs of Allium cepa. The secondary metabolites, total phenolic content and antiradical activity of the different onion organs were determined and compared to those of their roasted products (Gabou). The results obtained showed the presence of flavonoids and reducing compounds in the samples analyzed. Depending on the type of Gabou, leucoanthocyanins, mucilages, saponosids, anthraquinons, sterols and terpens were detected or not detected. The levels of total phenols and total flavonoids ranged from 65.6 to 78.6 mg EAG/100g and 61.1 to 65.2 mg EQ/100g respectively. The antiradical activity ranged from 24.3 to 94.4 mg EAA/100g. Roasting caused a significant increase (p<0.05) in antiradical activity and a no significant increase (p>0.05) in total flavonoid and phenol levels.

This plant from Cactaceae family was used as a natural coagulant for the different clarification tests. The preliminary phytochemical Screening of the powder of this plant showed that it contains tanins, saponins and mucilages. Flocculation and coagulation tests showed that Opuntia dillenii can be used in highly turbid water treatment. The removal efficiency varied from 89% to 93% for the turbidity and suspended solids, and from 4% to 15% for the obvious color in water when we used the optimum values of this natural coagulant (1 mL to 10 mL). The successive addition of this natural coagulant and the lime, gave a better elimination of turbidity and suspended solids, and a good reduction for the color. The removal efficiency of the turbidity and suspended solids became more than 95% and the one of the color between 67% and 94%.

Anthocyanins, leucoanthocyanins, catechics tannins, flavonoids, alkaloids, anthraquinones and reducer compounds were detected. However, saponins, coumarines and cyanogenic derivatives were not detected in the leaves extract. Taking into account of presence of these secondary metabolites in the plant extract, it could be suggested that this plant has a potential as a source of therapeutic agents. This supports the traditional use of the plant in curing human diseases. It is therefore suggested that further studies be carried out to isolate, purify and identify all active compounds present in all part of this plant.

In Benin, its overexploitation for ethnoveterinary uses could lead to its rarity or extinction in the long term. In this study, we evaluate the possibilities of its substitution by other Zygophyllaceae species. This study was based on optimal defense theory, which distinguished 2 categories of plants: K-strategist species and r-strategist species. Phytochemical screening was carried out based on aqueous extracts of the leafy stems of B. aegyptiaca and Guaiacum officinale (K-strategist species) and Tribulus terrestris and Kallstroemia pubescens (r-strategist species) for the identification of chemical compounds. The phenolic compounds were quantified by quercetin and vanillin methods. The extracts were tested against 5 bacterial strains responsible for severe diarrhea in bovines. Our results indicated the presence of many phytochemicals, such as alkaloids, flavonoids, ...

This pandemic spread very quickly around the world and has begun its proliferation in Africa. Respect of hygienic rules is one of the best preventive methods. This study explored street ready to eat foods as potential vehicle of human contamination with SARSCoV-2. For this, a bibliographic search was carried out from March 15 to December 7, 2020. From the results, it is well known that the transmission of the coronavirus by direct digestive route is ruled out for now. However, some studies are trying to demonstrate gastrointestinal manifestations and potential fecal-oral transmission of the virus. So ready to eat foods such as fruits and vegetables, bread, chips, donut, gari, snacks, homemade yogurt, cake, fried yam, roasted products, kilichi, .....

The essential oil from the leaves of this plant was extracted with a yield of 3% and then analyzed by GC/MS. Nine compounds, representing 94.46% of the chemical composition of the oil, were identified, three among them being majority: citronellal (65.45%), citronellol (13.5%) and isopulegol (10.33%). The contents of polyphenolic compounds of ethanolic and hydroethanolic extracts were respectively 4.52 mg EAG.g-1 and 4.38 mg EAGg-1 for total polyphenols, 78.76 mg ECg-1 and 81.56 mg ECg-1 for total flavonoids and 62.62 mg ECg and 67.09 mg ECg-1 for condensed tannins. The radical scavenging activity of hydroethanolic extract (IC50=0.23 mgmL-1 ) was more pronounced than ...
