Information gathered during the ethnobotanical survey and from the literature on the plant enabled chemical screening and the evaluation of its antioxidant activity. Extraction was carried out by sequential cold maceration with four solvents of increasing polarity: cyclohexane (CYHA), dichloromethane (DMC), ethyl acetate (EtOAc) and methanol (MeOH). The methanol extract gave the best yield (10.67%), followed by the ethyl acetate extract (1.1%), dichloromethane (0.84%), and cyclohexane (0.70%). Chemical screening carried out by tube reactions and thin layer chromatography confirmed the presence of: alkaloids (very little present), anthocyanins, catechins, sterols, anthraquinones and triterpenes, flavonoids, very abundant saponosides, narcotics specifically (Tetrahydrocannabinols) and very little coumarins. Chemical family analysis using a 96-well plate reader revealed high polyphenol content in all families compared to others. The polyphenol content of the EtAOc extract was high, at 496.3 ± 18.2 mg eq/g. The EtAOc extract inhibited DPPH more effectively than the others, with an inhibition percentage of 96.00 ± 0.89%. This same extract yielded a resistance index (RI = 0.35) less than one, confirming predominant antiplasmodial activity against the resistant strain. Extracts from the trunk bark of E. utile contained high levels of polyphenols and possessed antioxidant and antiplasmodial activities.]]> NGUIMALE KOUZOULOGBI BAPASSI Theodore, ZINGA Innocent, TCHINDA TIABOU Alembert, NGAISSONA Paul, KOUENI OUAKOUNDA Kevin Herman, YAMTHE Love, MOTOMBI Henri, WOROWOUNGA Xavier 2026-03-15 Science and Education Publishing 2026-03-15 2 14 19 25 10.12691/ajfst-14-2-1 http://pubs.sciepub.com/ajfst/14/2/2 Oreochromis niloticus broodstock with mean initial masses of 62.63 ± 1.23 g and 53.88 ± 4.54 g respectively were distributed in nine 9 m³ floating cages at a density (1 ind/m²) of one male for every three females. The different batches of fish were fed at 3-2.5% of biomass with feed containing 35% protein. Feed was distributed twice a day at 9 am and 5 pm for two months. At the end of the rearing period, all the fish were weighed individually and samples were dissected, the gonads removed and weighed. A sample of the ovaries was taken so that the oocytes could be counted under an electron microscope. In hapas, after two months of rearing, the condition indices for the males were 1.20 ± 0.00, 1.42 ± 0.10 and 1.63 ± 0.06. Gonadal weight ranged from 1.26 ± 0.08 to 1.53 ± 0.9 g. In females, absolute fecundity ranged from 572 ± 51 to 644 ± 44 oocytes/female. Oocyte diameter ranged from 3.02 ± 0.07 to 3.28 ± 0.02 mm. Relative fertility values ranged from 7683.2 ± 756.91 to 8257.28 ± 455.6.]]> Larissa-Pélagie Ella KOUADIO, Ahou Rachel KOUMI, Safiatou COULIBALY, Tia Jean GONNETY, Boua Célestin ATSE 2026-04-06 Science and Education Publishing 2026-04-06 2 14 26 31 10.12691/ajfst-14-2-2
