GC/MS Analysis of Essential oil distilled from Arum rupicola Boiss. var. rupicola (Araceae)

Aim: Arum rupicola Boiss. var. rupicola with a vernacular name of Dağ Sorsalı, are used etnobotanically for hemorroid, eczema, rheumatism, and cancer. Essential oil combination of A. rupicola var. rupicola, under the lower risk (lc) threatened category because of the excess gathering was investigated. Methods: The above ground samples of Arum rupicola Boiss. var. rupicola was collected from Palamut province of Antalya (Kaş) and essential oil was taken by hydrodistillation method with Clevenger apparatus. The essential oil composition was analysed by Gas chromatography (GC) and Gas chromatography/Mass Spectrometry (GC/MS) systems simultaneously. Results: As a result of, (E)-geranyl acetone (15%) was the main compound while hexahydrofarnesyl acetone (9.2%), nonanal (6.8%), heptacosan (6.5%), farnesyl acetone (5.0%), tricosan (4.9%), ve 2-dodecanone (3.8%) followed. Conclusion: Farnesyl acetone (5%) and hexahydrofarnesyl acetone (9.2%) sesquiterpenes were new records for A. rupicola var. rupicola volatile oil content. The only species is Arum creticum consisting α-farnesene (95%) as its taxonomical feature. A. rupicola var. rupicola has farnesyl acetone and hexahydrofarnesyl aceton being known a flagy and odourless species.
