A search for potential semiochemicals revealed nerolidol (6), albicanol (7), and the new 2,3-dihydrofarnesol
derivatives 8−10 in the temporal gland secretions of African elephants. A novel synthesis from (E,E)-farnesol (1) provided compounds 8−10 for GC−MS comparison to the natural products. This study confirms
the farnesol family as frequently occurring secondary metabolites in African elephant temporal gland
secretions.
