Exudates (DE) secreted from two shiitake mushroom mycelia (strains 1358 and L5458) were evaluated for their antioxidative properties and phenolic content. 1358DE and L5458DE showed distinct antioxidant activity in different in vitro assays, including scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, hydroxyl radical, superoxide anions and hydrogen peroxide; the ability to chelate ferrous ions; reducing power; hemolysis inhibition activity in rat erythrocyte; and lipid peroxidation inhibition (IC50 values of 1358DE and L5458DE were 3.3 and 132.6; 44.5 and > 1000; 26.9 and 53.7; 153.6 and >175.0; 176.0 and 521.0; 26.7 and 746.4; 47.8 and 736.9; and 3.1 and > 1000 μg/mL, respectively). Their total phenolic content was 237.33 and 24.08 mg gallic acid equivalent (GAE)/g of dry DE, respectively. Overall, these results show that 1358DE generally possesses better antioxidant properties than L5458DE, possibly due to its larger total phenolic content. Shiitake mushroom mycelial exudates, particularly of 1358DE, could be a good source of natural antioxidants.

Antioxidant Effects

A raw extract and four extractive fractions were obtained from Cedrus brevifolia (Cyprus cedar) bark. They were all studied regarding the phenolic content and profile using spectrophotometry and HPLC-DAD-ESI-MS. The antioxidant activity was investigated using in vitro assays: DPPH and ABTS radicals scavenging and reducing power assays. The ethyl acetate fraction had the highest total phenolic and proanthocyanidin contents; a taxifolin-O-hexoside, catechin, epicatechin and procyanidin oligomers (three dimers, two trimers) were identified in this fraction. The ethyl acetate fraction was found to possess the highest DPPH and ABTS radicals scavenging effects (EC50=13.9 ± 0.3 and 2.3 ± 0.0 μg/mL, respectively) and reducing capacity (EC50=9.1 ±0.1 μg/mL). Antioxidant effects were highly correlated with total phenolic and proanthocyanidin contents (r=0.89-0.99). These results suggest that Cedrus brevifolia bark is a new source of antioxidants.

In Vitro Antioxidant Activity

The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified and compared. We found that cv. Dama presented in general betters results when compared with cv. Leticia. Cv. Dama presented higher concentrations of chlorophyll a (2.26 mg/100 g fresh weight), total phenolic content (102.71 mg of chlorogenic acid equivalent/100 g fresh weight) and total intact glucosinolates (195.22 µmol of sinigrin equivalent/100 g fresh weight). Thus, cv. Dama exhibited higher values of in vitro antioxidant activity.
