Cedrus libani are widely used as traditional medicine in Lebanon for treatment of different infection diseases. In the present study we reported the phytochemical composition analyzed by GC-MS of wood essential oil and cones and leaves ethanol extracts. The main components of wood essential oil were himachalol (22.50%), beta-himachalene (21.90%), and alpha-himachalene (10.50%). Leaves ethanol extract was characterized by a high content of germacrene d (29.40%). The same extract obtained from cones essentially contained alpha-pinene (51.0%) and beta-myrcene (13.0%). Moreover, we investigated extracts, essential oil, and identified compounds for their in vitro antiviral activities against herpes simplex virus type 1 (HSV-1). Cytotoxicity was evaluated by MTT assay in Vero cells. Cones and leaves ethanol extracts exhibited an interesting activity with IC(50) of 0.50 and 0.66mg/ml, respectively, at non-cytotoxic concentration. A comparable activity was found when essential oil was tested (IC(50) of 0.44mg/ml).

Abstract
Cedrus libani are widely used as traditional medicine in Lebanon for treatment of different infection diseases. In the present study we reported the phytochemical composition analyzed by GC-MS of wood essential oil and cones and leaves ethanol extracts. The main components of wood essential oil were himachalol (22.50%), beta-himachalene (21.90%), and alpha-himachalene (10.50%). Leaves ethanol extract was characterized by a high content of germacrene d (29.40%). The same extract obtained from cones essentially contained alpha-pinene (51.0%) and beta-myrcene (13.0%). Moreover, we investigated extracts, essential oil, and identified compounds for their in vitro antiviral activities against herpes simplex virus type 1 (HSV-1). Cytotoxicity was evaluated by MTT assay in Vero cells. Cones and leaves ethanol extracts exhibited an interesting activity with IC(50) of 0.50 and 0.66mg/ml, respectively, at non-cytotoxic concentration. A comparable activity was found when essential oil was tested (IC(50) of 0.44mg/ml).I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
