Chemical composition and antifungal activity of the essential oils from native species of the ‘Campos de Cima da Serra’ region, South Brazil

This work aimed to evaluate the chemical composition, yield, and antifungal activity of essential oils (EO) native species from ‘Campos de Cima da Serra’ region, South Brazil. The Aloysia gratissima, lycioides, Blepharocalyx salicifolius, Cunila angustifolia, Myrciaria delicatula, Myrcia brasiliensis, Ocimum sp., Schinus polygama had an EO yield higher than 0.1% v/m. in vitro these was tested on fungi Alternaria alternata, Fusarium oxysporum, Botrytis cinerea, Sclerotinia sclerotiorum, Colletotrichum gloeosporioides, with concentration v/v. Chemically, sp. presented highest dissimilarity compared other species; EOs M. delicatula brasiliensis degree similarity. inhibited growth all fungi; B. salicifolius no inhibitory effect. remaining intermediate which also depended species.
