The composition of the essential oils (EOs) of O. vulgare L. EO and T. vulgaris EO, were analyzed by GC and GC-MS. Antifungal activities of the EOs and its main component, carvacrol, were evaluated against 27 clinical isolates of Malassezia furfur. Minimum inhibitory concentrations (MICs) were measured according to the broth microdilution protocols by Clinical and Laboratory Standards Institute (CLSI) modified for Malassezia spp. EOs and carvacrol showed low MIC values ranged 450-900 μg/ml against M. furfur.

In present study, the potential functional properties of the ethanolic extracts from peel, pulp, edible part and seeds of Capsicum annuum L. var. Cornetto di Pontecorvo were studied. The antimutagenicity against environmental pollutants and oxidative mutagens, the digestive enzyme inhibition, and the antioxidant properties were evaluated in relation to phenolic content. All the samples produced antimutagenic effects against 1-nitropyrene, 2-aminoantracene and tert-butyl-hydroperoxide, and inhibited α-amylase, without affecting α-glucosidase.
