Publisher: | MODESTUM LTD | Abstract: | Antioxidant capacity and antimicrobial activities of Russula delica Fr. (RD) extracts obtained with ethanol were investigated in this study. Four complementary test systems, namely DPPH free radical scavenging, beta-carotene/linoleic acid systems, total phenolic compounds and total flavonoid concentration, have been used. It was observed that inhibition values of both RD ethanolic extract and the standards (BHA and alpha-tocopherol) increased in parallel with the elevation of concentration in linoleic acid system. Total flavonoid amount was 8.71 +/- 0.56 mu g mg(-1) quercetin equivalents while the phenolic compound amount was 47.01 +/- 0.29 mu g mg-1 pyrocatechol equivalents in the extract. The antimicrobial activity of RD extract was tested in vitro by using the agar-well diffusion method. In our study, the RD extract showed antibacterial activity against. The RD extract did not exhibit anticandidal activity against Candida albicans. Therefore, the extracts could be suitable as antimicrobial and antioxidative agents in the food industry. | URI: | https://hdl.handle.net/11499/39515 https://doi.org/10.12973/ejac.2007.00010a |
