title: Identification of new sesquiterpenoids in cephalic secretion of cuckoo bee,Nomada lathburiana (Apoidea, Anthophoridae).
abstract: A series of new sesquiterpene ketones and norsesquiterpene ketones could be identified from the cephalic secretion of females of the cuckoo bee,Nomada lathburiana (K.). The major component proved to be 2,6,10-trimethylundeca-(5E)-2,5,9-trien-4-one. Large amounts of high-boiling-point straight-chain hydrocarbons serve as solvents for the volatile, unstable ketones.
