Abstract

Aim: Mushrooms of the genus Pleurotus have important nutritional and therapeutic properties, however, it is important to assess the differences in their properties depending on the species and even the strain. The antioxidant activity and total content of phenols in extracts from fruiting bodies of three strains of Pleurotus ostreatus, and one each of Pleurotus pulmonarius, Pleurotus eryngii, Pleurotus djamor var. roseus and Pleurotus citrinopileatus were evaluated, as well as, the proximal chemical composition of fruiting bodies of all strains were also determined.

Methodology: All strains were grown in wheat straw and the production of fruiting bodies were monitored. Three different extracts of fruiting bodies from each strain were obtained and their antioxidant activity and total content of phenols were measured.     

Results: Most of the strains showed an early fruiting production pattern (25 to 39 days), but in some strains it was intermediate (52 days) or late (67 days); the biological efficiency ranged from 42 to 95% and the production rate from 0.2 to 1.0. The proximal chemical composition was similar in all the strains. The phenol content ranged from 15.4 to 2.1 mg GAE g-1 of dry biomass. The percent inhibition of ABTS radical varied from 96 to 53 % and that of DPPH radical was between 98 to 24 %. Pleurotus citrinopileatus presented the highest antioxidant activity.      

Interpretation: Differences between strains and species, could be due to the fact that the phenotype is conditioned, among other factors, to the genotype in combination with the environmental conditions. The five Pleurotus species presented characteristics that confirm their use as a functional food, but there were differences in productivity and antioxidant capacity of fruiting bodies, which apparently depends on the interspecific and intraspecific variability of strains. Hence, further investigation is necessary to assess the effect of external factors.
