 The GC-MS analysis of the volatile constituents of crude honey residue (VCHR) and its in vitro antioxidant study of the crude honey residue (CHR) has been carried out. Hydrodistillation technique was employed in the extraction of the VCHR. The various candidates present in the extract of crude honey residue (ECHR) were identified using the gas chromatography-mass spectrometry (GC-MS) instrumental method of analysis. The ECHR was investigated for in vitro antioxidant study by exploring the free radical scavenging potential via the 2,2- diphenyl-1- picrylhydrazyl, DPPH technique.

Erectile dysfunction (ED) has posed problems among several married couples. This study evaluated the efficacy of combined ethanol root extracts of Terminalia avicennioides, Terminalia superba and seeds of Hunteria umbellata on Paroxetine-induced erectile dysfunction in male Wistar rats. Fresh roots of plants were collected, pulverized, extracted with 70% ethanol, dried in an oven at 400C and subjected to phytochemical screening. The plants were mixed in a ratio of 1:1:1; T. superba and T. avicennioides (TASM) mixed; T. superba, T. avicennioides and H. umbellata (TASHM) mixed.

this study is aimed at assessing the in-vitro effect of Aframomum daniellii seed extract, Aloe vera gel, Gongronema Latifolium leaf extract, Monodora myristica seed extract and honey on Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Candida albicans. Agar well diffusion method was used for the susceptibility test. The plates were incubated at 37 oC for 24 h. Extracts and diameter zones of inhibition were measured. All test organisms were susceptible to honey and Aloe vera gel, and a combination of both honey and Aloe vera gel.

This study assessed heavy metals (HMs) contamination in road dust using geochemical indices and their potential risks from an urban environment in Delta State, Nigeria. Fifteen road dust samples were sampled, digested in aqua regia and their HMs concentrations determined using atomic absorption spectrometry.

Tomato as vegetable and regarded as protective food is a very significant food crop globally. In this study, lycopene present in tomato and known for its anti-oxidative ability was correlated with fruit yield. Three varieties of tomato were selected and their growth rates were compared by measuring the length (cm) of stem from the day of transplanting till maturity (at flowering), on weekly basis. The three tomato varieties identified as Igb1/9/21, Igb2/9/21 and Igb3/9/21 were not significantly different in their growth.

The efficacy of methanol leaf extract of Jatropha curcas was investigated through in-vitro assay against Trypanosoma brucei-brucei in 96 well micro-titer plates. Maceration method was used to obtain the leaf extract using absolute methanol.

This study was carried out to evaluate the hypoglycemic, hematologic and hypolipidemic potential of berry oil in alloxan-induced adult Wistar rat. Five groups of Wistar rats (4 rats per group) Group 1 served as “Normal control” rats and received normal rat pellets and water. Diabetes mellitus was induced in Groups 2, 3, 4, and 5 by intraperitoneal injection of alloxan (160 mg/kg). Group 3 rats were treated with glibenclamide (5 mg/kg body weight), groups 4 and 5 received 500 mg/kg and 1000 mg/kg body weight of Berry oil daily respectively for 21 days via oral gavage.

The aim of this study was to evaluate the effect of poultry manure on the growth of Amaranthus caudatus with a view to establishing the optimum poultry manure treatment for its growth. The study was carried out between the months of February and May 2020, in a portion beside the botanical garden in the University of Benin, consisted of three (03) treatments namely PM1 (10%), PM2 (20 %), and PM3 (30 %) with poultry manure and control (PM0) in a randomized complete block design (RCBD) and replicated three times.

This study was carried out in the undergraduate project plot of the department of Plant Biology and Biotechnology, University of Benin from March to July 2020, to determine the impact of lead contamination on okra plant. A field experiment was conducted using 4 levels of Pb pollution namely 25, 50, 75, 100 mg/kg and control. Each bag containing 5 kg of air dried sandy loam soil was arranged in a completely randomized design (CRD) with three replicates. Five (05) seeds were sown in each bag. All bags were watered regularly. Plants were thinned down to one per bag after a week of emergence.

Phytochemical and gas chromatography and mass spectrometry (GCMS) analysis of the ethanolic extract of Uvaria ovata (Uo) roots was carried out. Phytochemical analysis showed high amounts of alkaloids, tannins and flavonoids, moderate amounts of saponins, terpenes and cardiac glycosides, while steroids and phenols were found in little quantities. Gas chromatography and mass spectrometry analysis revealed the presence of eleven compounds, of which D-Streptamine and Cystine were prominent.
