Antioxidant Properties of Cultured Mycelia from Four Pleurotus Species Produced in Submerged Medium

ABSTRACT

The ethanolic extracts of dried cultured mycelia of Pleurotus ostreatus, Pleurotus eryngii, Pleurotus florida and Pleurotus sajor-caju were analyzed for antioxidant activity in different systems. Tests used are; reducing power, free radical scavenging, superoxide anion radical scavenging, total antioxidant activity and metal chelating activitiy and so, total phenolic content was determined. The percentage inhibition of P. ostreatus, P. eryngii, P. florida and P. sajor-caju at 20 mg/mL concentration on peroxidation in β-carotene–linoleic acid system was 57.19, 60.68, 62.12, 58.81 %, respectively. The reducing power of P. eryngii was higher than the other samples, and its value was 0.86 at 10 mg/mL concentration. P. ostreatus, and P. sajor-caju proved to be better at scavenging superoxide anion radicals than the P. eryngii and P. florida. In the scavenging effect of DPPH radical test, P. ostreatus showed the highest activity potential and P. sajor-caju showed the strongest metal chelating capacity.
