The antioxidant activity and phenolic composition of six in vitro cultured blueberry seedlings were determined. Extracts were prepared in 85% ethanol from 30 days old in vitro cultured plants and used to evaluate the antioxidant capacities that included Ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazin (DPPH•) scavenging ability, total polyphenols (TP) and the partial p...

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 determi...

Antioxidant activity of the ethanol extract of Sida rhombifolia was determined by DPPH free radical, hydrogen peroxide scavenging assays, reducing power, total antioxidant capacity using phosphomolybdenum method, and rapid radical scavenging screening methods. Preliminary phytochemical screening revealed that the extract of S. rhombifolia leaves (SR-L), stem (SR-S) and roots (SR-R) possesses ph...

The methanolic extract of Clerodendrum viscosum Vent. (Verbenaceae) was evaluated for in vitro antioxidant activity by determination of total antioxidant capacity, assay of nitric oxide scavenging activity and reducing power test and in vivo antinociceptive effect in acetic acid induced writhing model in swiss albino mice. The results revealed the presence of pronounced antioxidant property as ...

This study was designed to investigate the in vitro and in vivo antioxidant activities of inulin. The in vitro assays demonstrated that the antioxidant activities of inulin, including the DPPH radical scavenging activity, ABTS scavenging activity and ferric reducing power, were weak and significantly lower than those of Vitamin C (P < 0.05). The influence of dietary supplementation with inulin ...
