Abstract

The essential oil obtained by hydrodistillation from aerial parts of Origanum x dolichosiphon P. H. Davis (Lainiaceae), a hybrid of O. amanum Post x O. laevigatum Boiss., was analyzed by GC/MS, Ninety-five compounds were characterized representing 92% of the oil. The major compounds were bicyclogermacrene (19.9%), beta-caryophyllene (13.0%), and germacrene D (10.8%). The antimicrobial activity of the oil was also determined.
