In five New GuineaNasutitermes (N. gracilirostris, N. novarumhebridarum, N. torresi, N. triodiae, and an undescribed speciesN. 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, inN. novarumhebridarum the sesquiterpenic fraction of soldier frontal gland secretion is equal to that of the monoterpenes.
在 5 种新几内亚大鼻白蚁（N. gracilirostris、N. novarumhebridarum、N. torresi、N. triodiae 和一种未描述的种 N. sp.F）中，我们检测并鉴定了 10 种倍半萜。这 8 种化合物（β-榄香烯、β-石竹烯、α-葎草烯、α-穆勒烯、γ-依兰油烯、β-依兰油烯、大根香叶烯-A 和 γ2-杜松烯）通过 GC 和 GC-MS（EI）进行了鉴定。两种不常见的倍半萜，(5R(), 7R(), 10S())-西莱烯-4(14),11-二烯和(5R(), 7R(), 10S())-西莱烯-3,11-二烯，通过 GC、GC-MS（EI、CI）、GC-FTIR 和单维及二维 NMR 进行了鉴定。虽然在大多数物种中倍半萜的含量较低或痕量，但在 N. novarumhebridarum 中，兵蚁额腺分泌物的倍半萜部分与单萜相当。
