Twenty-one volatile terpenes and terpenoids were found in Santschi (Hymenoptera: Formicidae), a native Chinese ant, by using headspace solid-phase microextraction (HS-SPME) coupled with gas-phase chromatography and mass spectrometry (GC-MS), which makes this ant one of the most prolific terpene producers in insect. A sesquiterpene with unknown structure (terpene 1) was the main terpene in workers and neocembrene in queens. Terpenes and terpenoids were detected in poison, Dufour's and mandibular glands of both workers and queens. Worker ants raised on a terpene-free diet showed the same terpene profile as ants collected in the field, indicating that terpene and terpenoid synthesis occurs in . .
采用顶空固相微萃取(HS-SPME)与气相色谱-质谱联用(GC-MS)技术,在中华弓背蚁(膜翅目:蚁科)中发现了 21 种挥发性萜类化合物和萜烯类物质,这使得该蚁成为昆虫中最具萜烯生产能力的物种之一。一种结构未知的倍半萜(萜烯 1)是工蚁中的主要萜烯,而在蚁后中则是新圆柏烯。萜类化合物和萜烯类物质在工蚁和蚁后的毒液、杜氏腺和下颚腺中均有检测到。在不含萜类化合物的饮食中饲养的工蚁表现出与野外采集的蚂蚁相同的萜类化合物图谱,表明萜类化合物和萜烯类物质的合成发生在蚂蚁体内。
