The present study aimed to investigate the antioxidant and antiradical activities of Wu Ling Shen, a popular medicinal fungus (Xylaria nigripes) used in traditional Chinese medicine preparations. Two different X. nigripes materials, the cultivated X. nigripes mycelia (XN) and a commercial X. nigripes product (XNP), were used to prepare the aqueous (XN-H vs. XNP-H) and ethanol (XN-E vs. XNP-E) e...

Different types of breads enriched with onion skin were studied. The objectives were twofold: to show and examine protein-phenolic interactions and to discuss results concerning phenolic content, antioxidant activity and protein digestibility in the light of in vitro bioaccessibility. Phenolic contents and antiradical abilities were linked with the level of onion skin supplement however, the am...

Flavonoids are plant secondary metabolites that insure the proper growth, development and protection of plants. Both in vivo and in vitro, they exhibit a broad biological activity that in many cases is connected with their antioxidative ability. The diversified ring structure of a flavonoid molecule with conjugated double bonds and numerous hydroxyl substituents ensures their antioxidative acti...

Aqueous mixtures of glycerol and 2-hydroxypropyl-β-cyclodextrin (CD), two non-toxic eco-friendly substances, were used as a means of extracting antioxidant polyphenols from oak acorn (Quercur robur) husks. The process was optimized by implementing a central composite (Box-Behnken) experimental design and response surface methodology, taking into consideration the critical parameters (independen...

Antiradical activity and free radicals before after gamma-treatment of beebread were investigated by Electron Paramagnetic Resonance (EPR) spectroscopy. A narrow signal the intensity which increased with dose was assigned to O-centred induced gamma rays. They are stable for 120 days irradiation. The irradiation effect on antioxidant potential content phenolic compounds studied. It found that to...
