Résumé :

In five New Guinea Nasutitermes (N. gracilirostris, N. novarumhebridarum, N. torresi, N. triodiae, and an undescribed species N. sp.F), we have detected and identified 10 sesquiterpenes. Eight of these compounds (β)-elemene, β-caryophyllene, α-humulene, α-muurolene, γ-selinene, β-selinene, germacrene-A, and γ2-cadinene) were identified by GC and GC-MS (EI). Two uncommon sesquiterpenes, (5R*, 7R*, 10S*)-selina-4(14),11-diene and (5R*, 7R*, 10S*)-selina-3,11-diene, were identified by GC, GC-MS (EI, CI), GC-FTIR, and mono- and bidimensional NMR. Whereas in most species sesquiterpenes are present in low or trace amounts, in N. novarumhebridarum the sesquiterpenic fraction of soldier frontal gland secretion is equal to that of the monoterpenes. © 1993 Plenum Publishing Corporation.
