Composition of the essential oils of Phlomis rigida Labill. and Phlomis samia L.

Abstract

The essential oils of Phlomis rigida Labill. and P. samia L. (Lamiaceae) obtained from the aerial parts by hydrodistillation were analyzed by GC and GC/MS. P rigida (albino and normal form) oils were found to be rich in beta-caryophyllene (31.2% and 38.7%, respectively) and beta-selinene (13.1% and 15.1%, respectively). P. samia oil contained germacrene D (33.8%) and beta-caryophyllene (6.4%) as major components.
