The extracts were also examined for their potential to inhibit the growth of clinical isolates following standard procedure. The major compounds identified in the hexane extract are a flavonoid, flavone 4’,5,7-triethoxy-3,3’,6- trimethoxy (20.23%) and a triterpenoid 17-(1,5-Dimethylhexyl)-6-hydroxy-5-methylestr-9-en-3-yl acetate (19.02%) while bufalin (18.71%) and tetratetracontane (12.91%) were the major compounds detected in the methanol extract. Steroidal triterpenoids are the major compounds present in the extracts as it accounted for 47% of the total detectable content in the hexane extract and 52% in the methanol extract. The steroidal triterpenoids which exist primarily as acetate in the hexane extract include cycloeucalenyl acetate, ergosta-5,7,22-trien-3-ol acetate, macdougallin, 17-(1,5-Dimethylhexyl)-6-hydroxy-5-methylestr-9-en-3-yl acetate, stigmasterol and β-sitosterol while the methanol extract contains 6,7-epoxypregn-4-ene-9,11,18-triol-3,20-dione, 11,18-diacetate, bufalin, olean-13(18)-ene, methyl ursolate, barringenol R1 and 7,8- epoxylanostan-11-ol,3-acetoxy. Hexane extract of the plant exhibited antifungal activity on Candida albicans while methanol extract revealed significant antibacterial activity on Pseudomonas aeruginosa and Staphylococcus aureus at all concentrations of the extract between 12.5 and 100 mg/mL, the activity being comparable to the standard antibacterial drug, Oxacillin. The leaves of Phyllanthus amarus is a potential source of steroidal triterpenoids which could serve as biomarker for the plant species. The extracts of the plant may also serve as a natural source of antimicrobial agents for the treatment of some microbial infections.Item Laboratory Practicals in Microbiology(Department of Microbiology, University of Ilorin, Nigeria, 2018) Olayemi, A.B.; Sani, A.; Oyeyiola, G.P.; Omojasola, P.F.; Kolawole, O.M.; Ahmed, R.N.; Saliu, B.K.; Anibijuwon, I.I.; Sule, I.O.; Agbabiaka, T.O.; Adebisi, O.O.; Udeze, A.O.; El-Imam, A.M.; Oke, M.O.; Kazeem, M.O.; Ajijolakewu, A.K.; Odebisi-Omokanye, M.B.; Laba, S.L.; Adetitun, D.O.; Gambari-Ambali, R.O.; Zakariyah, R.F.; Abioye, J.A.; Adam, A.I.; Olabanji, S.O.Item Rice Farmers’ Perception and Knowledge of Integrated Rice and Fish Farming in Selected Local Government Areas of Kwara State.(Cercetări Agronomice în Moldova, 2021-01-29) Olabode, D.A.; Omotesho, K.F.; Olabanji, O.P.; Ogunlade, I.; Adebisi, O.O.In spite of the numerous advantages associated with integrated rice and fish farming, deliberate adoption of this technique is still insignificant. This study examined rice farmers’ perception and knowledge of integrated rice and fish farming practice in Kwara State. A three- stage sampling procedure was used to select 149 rice farmers, while data was obtained through the use of a well- structured structured interview schedule. Data were analysed using descriptive statistics and the Pearson’s Product Moment Correlation (PPMC). The results show that 81.9% of the respondents were male with mean age of 38 years and an average of 14 years farming experience. Given the average mean score of 3.04 respondents had a positive perception of integrated rice and fish farming, while 63.8% of the respondents had moderate knowledge. Farmers’ identified high cost of irrigation materials (M.S.=2.59), poaching (M.S.=2.59), flooding (M.S.= 2.55) as major constraints to the practice of integrated rice and fish farming. Farmers’ perception had a significant relationship with knowledge of integrated rice and fish farming at p<0.05 level. Also, farmers’ age (r=0.300, p<0.000), level of education (r=0.287, p<0.000), farming experience (r=0.220, p<0.007), membership of cooperative society (r=0.176, p<0.032) and extension contact (r=0.204, p<0.013) had significant relationship with the knowledge level. The study concluded that the rice farmers had moderate knowledge and positive perception of integrated rice and fish farming. There is a need to provide incentives, such as irrigation facilities to farmers and provision of adequate training on integrated rice and fish farming in order to fully maximize the potentials therein.Item Sustainable Development in Nigeria: Prospects and Challenges.(General Studies Division, University of Ilorin, Ilorin, Nigeria., 2017) Olayemi, A.B.; Ijaiya, G.T.; Yahya, L.A.; Yusuf, N.; Adebisi, O.O.; Amusa, T.O.; Ahmed El-Imam, A.M.
