摘要：

The major antioxidants present in the essential (volatile) oils of oregano (Origanum vulgare, L.), summer savory (Satureja hortensis, L.) and thyme (Thymus vulgar is, L.) have been identified as carvacrol and thymol which have both been demonstrated to possess fungicidal and bactericidal properties. EPR spectra produced upon oxidation are inconsistent with the expected phenoxy Free radicals (RO(.)), but resemble those of galvinoxyl and anthronyl radicals. The EPR spectrum, in the case of carvacrol, is a pair of quintets with isotropic splittings, 0.325 and 0.080 millitesla (mT). ENDOR and TRIPLE resonance experiments have been performed and are indicative of the paramagnetic species being a substituted anthronyl. Further studies are being conducted to characterise these species and to investigate their potential roles during oxidative stress.
