Adeyeni egadeyeni@hallmarkuniversity.edu.ng E.T. Ayodele egadeyeni@hallmarkuniversity.edu.ng M. A. Onatolu egadeyeni@hallmarkuniversity.edu.ng <p>Health challenges like arthritis, asthma, diabetes mellitus, hypertension, epilepsy, and similar conditions pose significant concerns for humanity. These issues contribute to various health complications, fatalities, and economic losses. Addressing these difficulties requires investigating the capabilities of plants like Tetrapleura tetraptera, renowned for its medicinal attributes. Although its advantages are acknowledged, there is a lack of thorough investigation. This study focuses on analysing the isolation, characterisation, and antibacterial properties of ethanol extracts from Tetrapleura Tetraptera. It provides valuable information for developing drugs to treat infectious diseases and related conditions. Tetrapleura Tetraptera was collected from Ijebu Itele, Ogun State. About 400 g of the samples were soaked in 4000 mL of ethanol. Subsequently, ultrasonic sonicator was applied for agitation, followed by decantation of the extracts. The acquisition of Fourier transform infrared (FT-IR) spectra was carried out using a Perkin Elmer Spectrophotometer and Gas Chromatography-Mass Spectrometry (GC-MS) was employed for analysis. The TetrapleuraTetraptera’sanalysis involved the use of FT-IR and GC/MS spectroscopic data to ascertain potential bioactive compounds in the plant extractsPhytochemical analysis indicated the existence of diverse phytoconstituents, likely linked to the occurrence of secondary metabolites in the plant. The FT-IR spectra exhibited the existence of hydroxyl, ester, and ketones, featuring significant peaks at 3387.11 cm1, 1867.16 cm1, and 1635.69 cm1, correspondingly. The antimicrobial assessment demonstrated notable efficacy against examined fungi and bacteria, surpassing the performance of antibiotics outlined by the Clinical Laboratory Standard Institute (CLSI).The research findings suggest that TetrapleuraTetraptera's ethanolic extracts possess valuable bioactive compounds with significant medicinal properties. Consequently, these extracts could be considered as promising candidates for addressing infections induced by the fungi and bacteria investigated in the study.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 E.G.

Abare-Jen admin@chemsociety.org.ng J.B. Dimas admin@chemsociety.org.ng A.I. Chia admin@chemsociety.org.ng J.M. Yelwa admin@chemsociety.org.ng <p>Excessive application of pesticides for preservation of stored food has left in its wake residues of pesticides in diverse agricultural products and are now considered the leading cause of different health hazards in humans. In this research residual pesticide analysis in stored maize and beans were carried out in the last quarter of the year 2022 and the first quarter of the year 2023. A quick, easy, cheap, effective, rugged and safe Association of Official Analytical Chemists (AOAC) method was used to extract the pesticide residues from maize and beans. The grain markets of Iware, Jalingo, and Zing, were selected sites for collection of stored maize and beans. The samples were analyzed for eleven (11) organochlorine compounds for pesticide residues using Gas Chromatography- Mass Spectrometry technique. The pesticide residue level and the hazard index compared with EU . established MRL (maximum residue level) for pesticides. All the samples were found to contain pesticide residues, many of which have values above the EU standard. Residual pesticides investigated include, Delta Lindane, Alpha Lindane, Beta Lindane, Gamma Lindane, Heptachlor, Aldrin, Heptachlor epoxide, Endosulfan I., P, P' – DDE, Endrin, Endosulfan II, P, P' – DDD, P, P' – DDT and Methoxyclor. The results show that the mean concentration of these organochlorines pesticide detected were higher with respect to endosulfan I, having a concentration of 2.39 ppm, Aldrin, 1.74 ppm, and methoxychlor 1.10 ppm. Some of these concentrations are at an alarming level, somewhat much higher than the maximum residue limits (MRLs). This research findings suggest the ban on use of organochlorine pesticides for crop cultivations are not adhered to.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 L. Abare-Jen, J.B. Dimas, A.I.

Orji ikodiya.orji@uniport.edu.ng A. Njoku Eke-Anyanwu ikodiya.orji@uniport.edu.ng <p>Carbon-based adsorbents were prepared from groundnut husk by impregnation with H3PO4 and NaOH before or after carbonization. The adsorbents were characterised by Brunauer-Emmett-Teller (BET) adsorption/desorption isotherms, scanning electron microscopy (SEM), thermogravimetric/differential thermal analysis (TGA/DTA), and Fourier-Transform infrared spectroscopy (FTIR). These adsorbents were used for the removal of a turmeric based organic dye from aqueous solution. The results obtained from measuring the pH, temperature, and particle size effects on the adsorption process showed that the adsorbent impregnated with H3PO4 before carbonization (CA-B), achieved a higher percentage removal of turmeric dye at all parameters studied. The pseudo-second-order kinetic model explained the experimental data, the adsorption was controlled by liquid ?lm and intraparticle diffusion models simultaneously, the equilibrium data was a good ?t to the Langmuir adsorption isotherm model, and physisorption was the predominant sorption process. The results from this research have shown that adsorbents with suitable characteristics for the removal of turmeric dye from aqueous solution could be produced from groundnut husk.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 I.

Olaoye ayonposi@yahoo.com A. O. Fatoye ayonposi@yahoo.com S I. Kayode ayonposi@yahoo.com <p>Environmental pollution due to human activities is one of the greatest problems facing humanity and the developing countries need to have a better grip on controlling it. Phytoremediation is one of the promising technique that can help. Therefore, this research aims at investigating phytoremediation activity of Moringa oleifera (a tree common to the tropics and the sub-tropics) for the removal of metals in the dumpsites. The Leaves, shoot and root of the tree from four different dump site were collected, dried and ground. Also, the soil around the trees were collected. All the samples were analysed for their mineral content using ICP-OES. This study revealed that Al, As and Ca were both translocated and bioaccumulated in some of the trees. Also, more of the elements were translocated than those bioaccumulated in the trees. These results suggests that Moringa oleifera could be used to to clean up these metals in the environment. However, it also calls for caution on the location of the tree if it is to be used as food and medicine.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 A. B. Olaoye, A. O. Fatoye, S I.

Ujam patrick.obi@esut.edu.ng <p>Sphenostylis stenocarpa seeds are used locally to lower blood sugar level among diabetic patient in Southeastern Nigeria. The present study aimed at evaluating the effect of extract and fractions of Sphenostylis stenocarpa seeds on alloxan-induced diabetes in rat. The pulverized seed was soaked in methanol for 72h, filtered and concentrated to obtain the extract. The extract was subjected to Vacuum Liquid Chromatography (VLC) using gradient elution to afford n-hexane fraction, ethyl acetate fraction and methanol fraction respectively. Standard phytochemical method was used to screen the extract and fractions respectively. The method described by Lorke’s was used to carry out the acute toxicity study. The alloxan induced diabetic model was used to evaluate the antidiabetic activity in the rats. The phytochemical constituents present in extract and fractions were alkaloids, flavonoids, terpenoids. The acute toxicity study indicated no mortality or any behavioral changes even at 5000mg/kg body weight. The extract and fraction at 200mg/kg and 400mg/kg exhibited antidiabetic activity in dose dependent manner. The 400mg/kg reduced blood glucose level significantly at p &lt; 0.05 when compared to standard drug (glibenclamide). The Sphenostylis stenocarpa seeds have demonstrated an outstanding antidiabetic activity. The research has substantiated the use of the S. stenocarpa seeds to manage blood sugar level in folkloric medicine without record of adverse effect. This could be attributed to the present of flavonoids and terpenoids and alkaloids present in the samples with proven antidiabetic potentials. Further studies are required to isolate and characterize the bioactive compound responsible for the observed anti-diabetic activity.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 J. I. Ali, F. K.

Oyem hector.oyem@unidel.edu.ng I. M. Oyem hector.oyem@unidel.edu.ng <p>Storage chemistry of palm oil and groundnut oil samples were studied for their quality over the course of storage time and their impact on quality and health. Palm oil and groundnut oil samples were subjected to different moisture contents (water concentration) for some time. The acid values (AVs), free fatty acid (FFA) values, peroxide (P.O) vales, and iodine values (IVs) were determined using standard methods of the American Society of Oil Chemistry monitored during this period. Results indicate that AVs, FFA, and IVs increase with moisture content. Secondly, the AVs, FFA, and IVs of palm oil are higher than those of groundnut oil. Thirdly, the AVs, FFA, and IVs are directly dependent on the moisture content of the oils and increase correspondingly with an increase in water content. Generally, palm oil was found to be more susceptible to spoilage during storage and more affected by lipid oxidation. It is recommended that a threshold limit aw of ? 0.21 for moisture content be the standard for stored edible oils. Consumers should avoid storing and eating palm oil stored for a long period.</p> 2024-06-30T00:00:00+00:00 Copyright (c) 2024 H. H. Oyem, I. M.
