Abstract
|
|
|
|
Twenty-five wild edible mushrooms from Northeastern Thailand were analyzed for their antioxidant activities, proteins, sugars, β-glucan, and phenolic profiles. Results showed that T. clypeatus and V. volvacea exhibited the greatest scavenging activity (83.07 and 86.60%) and reductive power (9.79 and 8.42 g Fe(II)/kg, respectively). T. clypeatus recorded the highest content of (+)-catechin and naringenin (13.40 and 0.74 g/kg dw), with V. volvacea the highest amount of quercetin and quercetin-3-O-rutinoside (1.82 and 1.16 g/kg dw, respectively). Both T. clypeatus and V. volvacea also exhibited the greatest amounts of β-glucan (125.23 and 344.43 g/kg dw) and protein (343.30 and 452.20 g/kg dw, respectively) among the mushroom species evaluated. Results suggested that both T. clypeatus and V. volvacea were a good source of healthy compounds, namely β-glucan and flavonoids, and could be used to mitigate diseases involving free radicals.
