Dittany (Origanum dictamnus) as a source of water-extractable antioxidants

摘要

Extracts of dittany (Origanum dictamnus L.) made with evaluated (i) by electron spin resonance (ESR) spectrometry using the spin trapping technique for their efficiencies as scavengers of free radicals, and (ii) by measurement of oxygen depletionin a methyl linoleate emulsion for their efficiencies as chain-breaking antioxidants. Aqueous extracts of dittany most efficiently scavenged hydroxyl radicals as generatd by the Fenton reaction and this extract also most efficiently reduced oxygen consumption when initiated by metmyoglobin.
