Abstract

Background/Objectives

To evaluate antibacterial and antioxidant activities using Pleurotus eryngii extracts.

Method/Statistical analysis

TPC, TFC, DPPH, and ABTS activities were examined for antioxidant effects. In order to determine the antimicrobial activity, we also studied these extracts using six multi-resistant bacteria through paper disc diffusion.

Findings

The content of total polyphenols ranged from 1.67 mg GAE/g extract in acetone extract to 1.31 mg GAE/g extract in EtOH extract. The content of total flavonoid varied from 7.77 mg CE/g extract in EtAC extract to 0.61 mg CE/g extract in EtOH extract. At the result of DPPH activities of all extracts were higher than the ascorbic acid solution. DPPH activity of EtAC extract was the highest value at 81.0%. In addition, the highest ABTS activity was observed in EtOH extract at 88.4%. DPPH activity showed a stronger correlation with TPC and TFC. EtOH extract and acetone extract showed antimicrobial activity against six microorganisms. The EtOH extracts were the most effective against Enterobacter cloacae, and the most significant acetone extracts were the most effective for Escherichia coli.

Improvements/Applications

Based on this study, Pleurotus eryngii can be a good candidate for natural antioxidants and antimicrobials.
