The essential oils from buds of five Betula species growing in Turkey were investigated by GC-MS. A major component in the essential oils was shown to be 14-hydroxy-β-caryophyllene (6). The structure of β-betulenal (12) which was isolated from Betula essential oils was also confirmed by synthesis. Chemical reactions yielded 14-acetoxy-β-aryophyllene (15), 14- hydroxy-isocaryophyllene (10) and its acetate (14), giving evidence to the natural occurrence in Betula species of the formerly known α-betulenol acetate (3), β-betulenol (2) and β-betulenol acetate (4), respectively. Compounds 6, 9, 10, 12, and 15 were evaluated for antimicrobial activity.
