RETRACTED ARTICLE: Phytochemical Screening, Antioxidant and Antimicrobial activities of Senna occidentalis (L.) leaves Extract

Abstract

Phytochemical screening, antimicrobial and antioxidant activities of the hexane, ethylacetate and methanol crude extracts of Senna occidentalis (L.) leaves were studied in this work. The preliminary screening of the various extracts revealed the presence of tannins, alkaloids, reducing sugar, phenols, anthraquinones, resins, saponins and glycosides. The antimicrobial screening was carried out using the following organisms; Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Klebsiella pneumoniae, Candida albicans, Aspergillus niger, Penicillium notatum and Rhizopus stolonifer. The free radical scavenging capacity using hydrogen peroxide was equally determined to evaluate the antioxidant activities of the extracts. The results obtained showed that Senna occidentalis (L.) leaf extracts have interesting pharmacological active compounds with great radical scavenging and antimicrobial effects and as such could be used in ethno medicine for treatment of some infections and ailments.
