A new bisabolane derivative of Leontopodium andersonii.
Phytochemical investigations of the roots of Leontopodium andersonii C. B. Clarke (Asteraceae) resulted in the isolation of a new bisabolane sesquiterpene derivative. The structure of the highly substituted derivative (1R*,5S*,6S*)-5-(acetyloxy)-6-[3-(acetyloxy)-1,5-dimethylhex-4-enyl]-3-methylcyclohex-2-en-4-on-1-yl(2Z)-2-methyl-but-2-enoate was established by 1- and 2-D-NMR spectroscopy and is the first report of a bisabolone derivative of the genus Leontopodium.
