Essential oils from the buds of Betula spp. growing in Turkey
Özet
The essential oils from buds of Betula browicziana A. Guner, B. litwinowii Doluch., B. medwediewii Regel, B. pendula Roth and B. recurvata V. Vassil. (Betulaceae) were either hydrodistilled using a Clevengertype apparatus or were subjected to Likens-Nickerson simultaneous distillation-extraction (SDE) when the plant material amounts were insufficient. The resulting bud essentiat oils were analysed by GC-MS. Main components were detected as 14-hydroxy-beta-caryophyllene (1) and 14-hydroxy-4,5-dihydro-beta-caryophyllene (2) in all the oil samples.
