France Biología solvent mushroom extraction Grifola gargal Antioxidant activity The influence of different solvents on the extraction yield, antioxidant activity and polyphenolic and flavonoid contents in extracts of Grifola gargal fruit bodies was investigated. Solvents such as acetone, ethanol, ethyl acetate, n-hexane, water, and ethanol-water mixtures were used for extraction. Antioxidant capacity was evaluated by four different assays, namely, 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) and 2,2-diphenyl-1-picrylhydrazyl radical scavenging, reducing power and chelating ability. Acetone extracts showed the highest free-radical scavenging activity equivalent to 96.0 mg ascorbic acid/L in the 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) assay, and 92.9% in the 2,2-diphenyl-1-picrylhydrazyl assay. Water-ethanol extracts showed a strong reducing power (135.6 mg ascorbic acid/L), while ethyl acetate extracts had a chelating ability of 19.8%. Water extracts showed the highest flavonoids contents (6.1 mg/100 g), while water-ethanol extracts (20:80, v/v) had the highest polyphenols contents (63.8 mg/100 g). The antioxidant activities [both 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) free-radical scavenging and reducing power] correlated well (R<0.93) with the polyphenol and flavonoid contents of the extracts. Specific antioxidant attributes of Gargal mushroom extracts were strongly dependent upon the kind of solvents used for extraction. 2009 artículo científico 1534-2581 https://www.redalyc.org/articulo.oa?id=68521102 en http://www.redalyc.org/revista.oa?id=685 Micología Aplicada International application/pdf Colegio de Postgraduados Micología Aplicada International (México) Num.1 Vol.21 |
