Antioxidant and antimicrobial properties of ethanolic extract fromLepista nuda (Bull.) Cooke

Year: 2006

Type: article

Abstract: Antioxidant capacity and antimicrobial activities of Lepista nuda (Bull.) Cooke extracts obtained with ethanol were investigated. Four complementary test systems, namely DPPH free radical scavenging, β-carotene/linoleic acid systems, total phenolic compounds and total flavonoid concentration, have been used. Linoleic, acid inhibition values of L. nuda ethanolic extract, BHA and α-to copherol standards were found to be 84.3% 98.9% and 99.2% respectively in the concentration of 160μg/ml. Total flavonoid amount was 8.21 ± 0.56 μg mg −1 quercetin equivalent while the phenolic compound amount was 48.01 ± 0.29 μg mg −1 pyrocatechol equivalent in the extract. The antimicrobial activity of L. nuda extract was tested in vitro by using the agar-well diffusion method. The L. nuda extract showed antibacterial activity against Micrococcus flavus, Micrococcus luteus, Bacillus cereus, Yersinia enterocolitica, Staphylococcus aureus, Salmonella enteritidis and Escherichia coli . The L. nuda extract did not exhibit antican didal activity against Candida albicans . The extracts could be suitable as antimicrobial and antioxidativeagents in the food industry.
