This research work is therefore necessitated to determine the antimicrobial, phytochemicals and antioxidant activity of Acalypha fimbriata. The leaf of Acalypha fimbriata were Soxhlet extracted, reconstituted, and screened for phytochemical constituent of antimicrobial importance. Conventional biochemical characterization was carried out on the isolates of Staphylococcus aureus, Escherichia coli Pseudomonas aeruginosa and Klebsiella pneumoniae obtained for the research work and the antimicrobial activity of the plant sample was determined using the agar well diffusion technique. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) of the extract were determined by broth dilution method on the isolates. The antioxidant activity of the extract was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and Graphpad prism were used to interprets the data. Alkaloids, flavonoid, anthraquinones, tannins and saponins was found in the leaf extract. Staphylococcus aureus exhibited highest zone of growth inhibition (28mm) at 100mg/ml while Pseudomonas aeruginosa had the lowest (14mm) at 100mg/ml from the antimicrobial assay. In the determination of the minimum inhibitory concentration and minimum bactericidal concentration, Staphylococcus aureus exhibited MIC and MBC at 0.625µg/ml and 12.5 µg/ml, while Pseudomonas aeruginosa elicited MIC and MBC at 10 µg/ml and >10 µg/ml of MIC and MBC respectively. Themethanol extract of the plant acted as hydrogen/electrons donor or scavenger of radicals with fifty percent inhibitory concentration (IC50) of 59.83 µg/ml while that of Ascorbic acid (standard) was found to be 92.70 µg/ml using. The varied MIC’s and MBC’s obtained coupled with the values recorded for the antioxidant radicals validate the antimicrobial and antioxidant potential of Acalypha fimbriata that can be explored for therapeutic option, if further purified and optimally processed.","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120962110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study examined the hepato-protective effects of pooled ethanolic extract of Psidium guajava and Carica papaya leaves in rats challenged with Cadmium (Cd). Exactly 200g of the grounded leaves were soaked in ethanol for 48hours and was concentrated after filtration using a rotary evaporator. Fifteen adult female rats (150¬-±10g) were randomly assigned into three groups: Group 1 (control: received feed and water alone), Group 2 (Cd group; received single dose of Cd, 30mg/kg b wt, Group 3 (Cd + extract: received Cd as in group 2 and leaf extract 200mg/ kg bwt daily for 2 weeks). Rats were slaughtered and samples were taken for biochemical examination at the conclusion of the study period. When compared to controls, exposure to Cd alone resulted in a significant increase (p<0.05) in the activities of the alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH), as well as an increase in the level of total protein (TP). Hepatocytes exposed to cd underwent histological changes as well. As opposed to rats exposed to Cd alone, there was a significant decrease in the values of ALT, AST, ALP, LDH, and TP when Cd-challenged rats were given the combination ethanolic extract of P. guajava and C. papaya. The outcomes suggest that the biherbal combination of P. guajava and C. papaya can shield liver cells against Cd damage.","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117149646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
