(+)‐β‐Eudesmol (7), (+)‐10‐epi‐elemol (8) , (−)‐(Z)‐dihydrofarnesol (3) , and an alcohol believed to be a guai‐9‐en‐11‐ol (4) have been isolated from Galbanum resin. Together with (‐)‐β‐dihydroagarofuran (1) and epi‐ligulyl oxide (13) (reported naturally occurring for the first time), 10‐elemol (8) and 10‐epi‐junenol (2) involve the enantiomeric stereochemistry at C (10) compared with β‐eudesmol 7 , and guaiol 5 , the major sesquiterpene alcohol of Galbanum.
