Abstract

This research provides the antioxidant activities of locally produced rice in the Northern and Western regions of Nigeria, with a focus on Kebbi rice and Igbemo rice. The study utilizes the Ferric Reducing Antioxidant Power (FRAP) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assays to evaluate the antioxidant capacity of these rice varieties. In which the sample was extracted using solvent extraction method after which the antioxidant (AO) activity of the rice samples as ferric-reducing power, is determined using a modified FRAP (ferric reducing/antioxidant power) assay Sodium phosphate, buffer solution, pipettes, test tubes, centrifugal machine, TCA, KFC and reagent such as Fe(iii) solution were used to analyse the ferric reducing antioxidant power (FRAP) of the sample. Also, Methanolic solution, and spectrophotometer to measure absorbance at 516nm is used to determine the free radical scavenging ability of the extract against DPPH (1, 1- diphenyl-2-picryhydrazyl). Results reveal that Kebbi rice exhibits higher FRAP values compared to Igbemo rice, indicating superior antioxidant activity in the FRAP assay. Conversely, Igbemo rice demonstrates higher DPPH values than Kebbi rice, suggesting greater antioxidant potency in the DPPH assay. These findings underscore the variability in antioxidant properties among different rice varieties and highlight the importance of considering multiple assays for a comprehensive assessment of antioxidant activity. Understanding the antioxidant profiles of indigenous rice varieties like Kebbi and Igbemo rice is crucial for promoting their consumption and enhancing food security in Nigeria. Further research is warranted to elucidate the specific antioxidant compounds responsible for the observed differences and explore their potential health benefits.

Abstract

The role of chemistry in the promotion of national development cannot be overemphasized, consequently there is need to put in place all measures to sustain the acquisition of knowledge such as the number of student’s subscription. This study explores the factors influencing the low enrollment of students in chemistry education at tertiary institutions, focusing on the Federal College of Education Okene, in affiliation with the University of Ibadan. The study utilized an opinion survey research design and descriptive research method to systematically investigate the factors influencing chemistry enrollment. The validated questionnaire shows a reliability coefficient of 0.87, using descriptive research methods for data analysis. The population consisted of 120 students, with 40 from the chemistry department and 80 from the biology department selected randomly. A quantitative research approach was employed for data analysis, using the statistical tools of frequency, percentage, mean, and a significance test to make decisions based on the research questions posed. The study signifies challenges in student enrollment and suggests interventions to improve the attractiveness and effectiveness of chemistry education programs.
