The essential oils from buds of Betula browicziana A. Güner, B. litwinowii Doluch., B. medwediewii Regel, B. pendula Roth and B. recurvata V. Vassil. (Betulaceae) were either hydrodistilled using a Clevenger‐type apparatus or were subjected to Likens–Nickerson simultaneous distillation–extraction (SDE) when the plant material amounts were insufcient. The resulting bud essential oils were analysed by GC–MS. Main components were detected as 14‐hydroxy‐ β ‐caryophyllene ( 1 ) and 14‐hydroxy‐4,5‐dihydro‐ β ‐caryophyllene ( 2 ) in all the oil samples.
