The aim of the study was to screen for antibacterial activity of endophytic fungi isolated from Azadirachta indica and Mentha piperita. Endophytic fungi were isolated from healthy leaves of A. indica and M. piperita. The isolates were screened for their antibacterial activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Antibacterial activity of ethyl acetate extracts of the isolates was also determined. A total 35 endophytic fungi were isolated out of which 11 showed antibacterial activity against at least two of the test bacterial isolates. Ethyl acetate extracts of these 11 endophytes had varying degree of antibacterial activity with zones of inhibition ranging from 10±10 mm to 26±0.5 mm. Result of this study revealed that endophytic fungi isolated leaves of A. indica and M. piperita produce bioactive compounds with antibacterial activity against the test bacterial isolates.","PeriodicalId":431221,"journal":{"name":"Algerian Journal of Biosciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126882175","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}

The leaf is used to treat fever, conjunctivitis, febrifuge, coughs, sexually transmitted diseases, diarrhea, and as a tonic. Despite it being used in ethnomedicine to treat various sicknesses, the safety profile of the leaf extract has not been reported. This study was aimed at testing the acute and sub-acute toxicological assessments of the aqueous leaf extract of Combretum platypterum.The acute study was carried out using mice and rats. In sub-acute experiments, the animals received 0.5, 1, and 2.5 g/kg of the plant extract orally per day for 28 days. The first weight and the last weight were taken. The liver, spleen, kidney, heart, lungs, and stomach were obtained, weighed, and fixed. Blood was obtained for haematology and biochemical assays. The LD50 of the root extract was indeterminable since there was no death in the mice and rats used. The leaf extract significantly increases (p<0.05) the body weight at the dose of 2.5g/kg compared to control. The body weight index was not affected compared to control (p>0.05). At 0.5 and 1 g/kg, the extract significantly increased the level of monocytes (p < 0.05) compared to the control. haematological parameters were not affected. Upon bichemical analysis of the leaf extract, 2.5 g/kg significantly (P<0.05) increased the level of HDL and 0.5 and 1 g/kg significantly (P<0.05) increased the level of TRI compared to control. Other parameters were not affected. This study shows that aqueous root extract is safe.","PeriodicalId":431221,"journal":{"name":"Algerian Journal of Biosciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115011000","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}

After giving informed consent, structured questionnaires were used to collect demographic data from the participants, including age, education level, and pest control strategy. Two vegetable farms were then selected, of which one was in the metropolis (labeled A) and the second was on the outskirts (labeled B). After visual counting of pests on the vegetables, they were captured with swoop nets, aspirators, and forceps, and then identified in the laboratory using hand lenses and identification keys. The results show that the vegetable farmers were middle-aged men with at least a secondary school education, and chemical application was the most widely used pest control measure in the area. Farm A had 127 pests, with Solanum lycopersicum accounting for 57 (44.88%), followed by Amaranthus spp. (23, representing 18.11%), Brassica oleracae (19, representing 14.97%), Lactuca sativa (18, representing 14.17%), and Allium cepa (10, representing 7.87%). Farm B had 101 pests, of which Solanum lycopersicum accounted for 44 (43.56%), followed by Amaranthus spp. with 22 (21.78%), Lactuca sativa and Brassica oleracae each had 13 (12.87%), and Allium cepa had 9 (8.92%). Aphids were the most predominant pests with 69 members, followed by hornworms with 32, thrips and pumpkin bees each had 27, cutworms had 26, and white flies had 24, respectively. Overall, the results showed that there is a heavy pest infestation of vegetables in Ikorodu.

The analysis consisted of antioxidants extraction, following the solid-liquid extraction with ethanol 40% (v/v), their quantification and determination of their antioxidant activity by two methods (reducing power and DPPH• Test). Results show that total phenolic content (TPC) ranged from 74.04 to 92.83 mg GAE /100g Extract. The Sidi-Fredj variety has the best rate followed, by the Taoura and Drea ones. Concerning, flavonoids and tannins, the Taoura variety contains higher concentrations corresponding to 2.67 mg QE/100g and 6.60mg CE/100g. activities of extracts of three varieties show similar performance; the EC50 for the reduction of ferric iron 0.05g/mL for all extracts, whereas the EA is more important in Sidi-Fredj and Drea seeds extracts. Regarding the scavenging of DPPH •, Drea and Sidi-Fredj varieties show the highest capacity equals to 0.20g/mL. Linear correlations between the different studied activities and some antioxidants (flavonoids, tannins) rates were noticed; indicating their participation in the obtained effect. \u0000Analysis of the oil by HPLC revealed the presence of phenolic compounds including gallic acid and a form of vitamin E (α-tocophérol), capable of expressing biological activities; Anti-oxidants and vitamins.
