The antioxidant properties of two wild edible mushroom species from the northeast of
Portugal, Lactarius deliciosus (L.) Gray and Tricholoma portentosum (Fr.) Quél., were
evaluated. Methanolic extracts from the entire mushroom, the cap and the stipe, separately,
were screened for their reducing power and free radical scavenging capacity by chemical
assays. The total phenolic content was determined, in order to assess its effect on the
extract's antioxidant activity. Both two species showed antioxidant potential; but L. deliciosus …

Areca is a traditional Chinese medicinal plant used to treat a variety of diseases. The
antioxidant capacities of areca flower extracts were evaluated by using superoxide radical
scavenging activity and reducing power, total phenolic content and total flavonoid content
were also detected. In all the tested models, the areca flower extracts showed their ability to
scavenge superoxide radical and reducing power in a does-dependent manner. The
distilled water (AFW) extract had higher superoxide radical scavenging activity and reducing …
