Composition of Essential Oils of Calamintha nepeta (L.) Savi Subsp. nepeta and Calamintha nepeta (L.) Savi Subsp. glandulosa (Req.) P.W. Ball

Abstract

The oils were extracted from aerial parts of the two subspecies of Calamintha: subsp. nepeta (A, B, C) and subsp. glandulosa (D, E) using an Eppendorf Microdistiller®. Oils were analyzed by GC/MS. Trans-piperitone oxide (44.4 %), piperitenone oxide (11.7 %) and limonene (7.1 %) were detected as main constituents in sample A; pulegone (11.9 %), menthone (11.9 %), carvacrol (10.0 %) and limonene (7.5 %) were found as main constituents in sample B; trans-piperitone oxide (30.9 %), caryophyllene oxide (7.8 %) were detected as main constituents in sample C of C. nepeta subsp. nepeta oils and pulegone (19.5 %), menthone (9.7 %), caryophyllene oxide (7.9 %), trans-piperitone oxide (5.7 %) and menthol (5.0 %) were detected as main constituents in sample D; trans-piperitone oxide (34.2 %), limonene (17.3 %) and piperitenone oxide (10.8 %) were found as main constituents in sample E.
