Infection effect of Cedar atlas wood by Trametes pini and Ungulina officinalis on chemical composition and antibacterial and antifungal activities of essential oils

Chemical composition and antibacterial and antifungal activities of the essential oils of Atlas Cedar were studied according to sanitary conditions of wood. The essential oils obtained from uncontaminated sawdust and contaminated by Trametes pini have sensibly identical chemical composition with himachalenes (alpha-, gamma- and beta-) and E-alpha-atlantone as major components, but this oils don't have antibacterial and antifungal activities. Those obtained from wood attacked by Ungulina officinalis, which have a different chemical composition, have a bacterial activity for a concentration of 2 mul/ml and a less antifungal activity.
