Antibiofilm, Antioxidant, Antimutagenic Activities and Phenolic Compounds of Allium orientale BOISS
This is the first study to investigate the antibiofilm, antioxidant and antimutagenic activities and phenolic compounds of Allium orientale. Antimicrobial activity of ethanolic extracts of A. orientale was determined by a broth microdilution method. Antibiofilm activity was evaluated by microplate biofilm assay. The antioxidant activity was determined using three complementary assays; namely, D...
متن کاملAntioxidant, Phenolic Compounds Concentration, Xanthine Oxidase and Tyrosinase Inhibitory Activities of Pleurotus cornucopiae
Pleurotus cornucopiae has been widely used in nutritional and medicinal purposes. This study was initiated to screen the antioxidant activities, tyrosinase inhibitory effects on the fruiting bodies of P. cornucopiae extracted with acetone, methanol and hot water. The antioxidant activities were performed on β-carotene-linoleic acid, reducing power, DPPH, ferrous ions chelating abilities, and xa...
متن کاملPhenolic compounds and antioxidant activities of Liriope muscari.
Five phenolic compounds, namely N-trans-coumaroyltyramine (1), N-trans-feruloyltyramine (2), N-trans-feruloyloctopamine (3), 5,7-dihydroxy-8-methoxyflavone (4) and (3S)3,5,4'-trihydroxy-7-methoxy-6-methylhomoisoflavanone (5), were isolated from the fibrous roots of Liriope muscari (Liliaceae). Compounds 2-5 were isolated for the first time from the Liriope genus. Their in vitro antioxidant acti...
متن کاملAssessing antioxidant and prooxidant activities of phenolic compounds.
Methods for determining primary antioxidant activity were evaluated. A beta-carotene bleaching method and a free radical method using 2, 2-diphenyl-1-picrylhydrazyl (DPPH(*)) were modified to rapidly test samples for potential antioxidant activity. Malonaldehyde production in a linoleic acid emulsion system assayed by an HPLC method was also used to determine antioxidant and prooxidant activiti...
