Total phenols and antioxidant activity of commercialand wild mushrooms from Chihuahua, Mexico

Three wild edible mushrooms (Agaricus sp., Boletus sp., and Macrolepiota sp.) from the North of Mexico (Chihuahua state) and two commercial species (Agaricus bisporus white strain and Portabella: Agaricus bisporus brown strain) were analyzed to determine their proximate composition, total phenols and antioxidant activity. Wild mushrooms presented lower humidity values with respect to commercial species. Other proximate parameters such as total protein, lipids, ashes and carbohydrates were similar to those reported for edible mushrooms. Total phenols and antioxidant activity (Ferric Reducing/Antioxidant Power assay, FRAP) were determined from 80% methanol extracts. Wild Mushrooms had higher phenol content and antioxidant capacity than commercial mushrooms. A direct correlation between phenols and antioxidant activity (r(2) = 0.986) was observed. Due to these characteristics, wild mushrooms could be considered as a complement in the diet for the health benefits they present.
