In the present study, phytochemical analysis of Albizia chevalieri was carried out as this plant may be among one of the imperative medicinal herbs for the treatment of ailments like malaria, diabetes, diarrhea, and dysentery. Phytochemical analysis was carried out for the three Arial parts of the plant extracted with three different solvents (methanol, ethyl acetate and n-hexane). Qualitative analysis showed that methanol extracted almost all the secondary metabolites in all the three Arial parts of the plant. After quantification, it was observed that methanol Root extract was having the highest phenolic contents (44.83µg/GAE/g), followed by methanol leaf extract (38.89 µg/GAE/g), and methanol stem bark extract (22.00 µg/GAE/g). Root ethyl acetate extract (8.19 µg GAE/g), stem bark ethyl acetate extract (13.49 µg GAE/g), and leaves ethyl acetate extract (23.66 µg GAE/g), while n-hexane extracts were having a very low phenolic content with; n- hexane root (0.66 µg GAE/g), n-hexane stem bark extract (2.69 µg GAE/g), and n-hexane leaves extract (7.80 µg GAE/g). The presence of high amount of phyto-constituents suggest that A.chevalieri may have high medicinal value and it can be carefully studied in order to extract the natural compounds present, which may be beneficial to human beings and that which may be commercialized for higher production than using synthetic drugs with side effects.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134609057","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}

Information on parts of the plants used and the mode of administration in the treatment of the diseases was obtained. Twenty-four species of plant, belonging to 15 families, used in treating 20 conditions, in humans, were recorded during the survey. The family Fabaceae, with eight species, recorded the highest mention. Woody species (80%) dominated herbaceous ones (20%). Of the 20 conditions treated with these plants, 13 were symptoms (e.g., Jaundice), five were physiological diseases (e.g., hypertension) and three were infectious diseases (e.g., malaria). The plants were identified by the first author and their voucher specimens were preserved at the herbarium of the Department of Biological Sciences of Abubakar Tafawa Balewa University, Bauchi, Nigeria. This study reveals a wealth of indigenous knowledge that may be exploited for the benefit of mankind: Thus we recommend further investigation to test the claimed medicinal properties of these plants.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129546806","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}

Results from weight loss measurements revealed an increase in inhibition efficiency with increasing temperature and inhibitor concentration which indicates that AM leaf extracts sufficiently inhibits corrosion of stainless steel through chemisorptions of its constituent molecules. Hydrogen evolution results show that the inhibitor appreciably reduced the volume of hydrogen evolved which implies an obstruction of the cathodic reaction and reduction of corrosion rate. Data obtained from the potentiodynamic polarization scan revealed that AM leaf extracts shifted corrosion potentials of AISI 316L to more positive potential with increasing inhibitor concentration indicating a predominant anodic protection with passivation enhancing capabilities. Surface elemental analysis revealed that the formed corrosion products on the steels surface included heteroatom from the leaf extract which confirms that inhibition action was through adsorption of AM leaf extracts constituent molecules on the surface of the metal via complex chelating ligands. Adsorption of the leaf extract was seen to obey Langmuir isotherm at high temperature and obtained thermodynamic parameters were discussed.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124849263","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}
