Polarography as a technique of choice for the evaluation of total antioxidant activity: The case study of selected extracts and quinic acid, their antidiabetic ingredient.

This study was focused on screening of the total antioxidant activity of the selected extracts of the mushroom and quinic acid, one of their antidiabetic ingredients, by an uncommon electrochemical assay. Indeed, direct current (DC) polarographic HydroxoPerhydroxo Mercury(II) Complex (HPMC) assay based on decrease of anodic limiting current originating from HPMC formation in alkaline solutions of hydrogen peroxide at potential of mercury dissolution, observed upon gradual addition of antioxidants, was applied herein for the estimation of the natural products' antioxidativity. Quinic acid was found to exhibit most promising antioxidant potential (4.

filtrate extract, a novel neuroprotective agent of natural origin.

acetylholinesterase (AChE) inhibitory activity of an autochthonous sample of the mushroom (encompassing fruiting body FB, mycelia M and filtrate F from the submerged cultivation) was the subject of this study. F extract exhibited rather potent anti-AChE activity (73.0 ± 1.

Effects of vanadate on the mycelium of edible fungus Coprinus comatus.

Vanadate is proposed to play a pivotal role in application of edible fungus Coprinus comatus for medical purposes. In this study the concentration of extracellular vanadate acceptable for the submerged cultivation of C. comatus mycelium was established.

The polysaccharide extracts from the fungi Coprinus comatus and Coprinellus truncorum do exhibit AChE inhibitory activity.

The polysaccharide (PSH) extracts from the edible mushroom species Coprinus comatus and Coprinellus truncorum were screened in liquid for their acetylcholinesterase inhibitory (AChE) activity. Both extracts were found to display inhibition of the aforementioned enzyme reaching similar IC values of 0.62 ± 0.

Trametes versicolor ethanol extract, a promising candidate for health-promoting food supplement.

This study aimed to estimate antiradical, antioxidant (AO) and cytotoxic activities of the fungus Trametes versicolor ethanol fruiting body extract. The extract was found to effectively scavenge both O and NO (29.62 and 52.
