Chemical diversity of essential oils within the origanum dubium boiss. Population

Origanum dubium Boiss. is one of the economically important wild oregano species and it is intensely collected from its natural habitat in Antalya, Turkey. Carvacrol chemotype of Origanum dubium is used mainly for essential oil production due to its high essential oil content. In this study, chemical diversity of Origanum dubium was investigated in order to develop new cultivars with improved essential oil yield and carvacrol content using clone selection method under cultivated condition. Essential oils obtained by hydrodistillation of the aerial parts of Origanum dubium were analysed by GC-MS and 24 major components were identified. Among the selected genotypes, carvacrol was the major component and followed by p-cymene, ?–terpinene, myrcene and ?-thujene, respectively. The essential oil yields were varied between 5.0% to 14.0%; carvacrol rates were varied between 73.76% to 88.21%; and p-cymene rates were varied between 3.16% to 9.10%. © 2019, Badebio Biotechnololgy Ltd.
