利用自动固相动态提取和气相色谱-质谱法，我们对排卵雌性非洲象(Loxodonta Africana)的尿液化学信号进行了研究，发现了树皮甲虫聚集信息素Frontalin、Exo-brevicomin和Endo-brevicomin，以及它们的前体和蚜虫报警信息素(E，E)-α-法尼烯和(E)-β-法尼烯。测定了短链菌素类药物的对映体比例。此前在亚洲大象中发现了常见的昆虫/大象信息素，即(Z)-7-十二烯基乙酸酯和佛波特林，这表明目前的发现可能对非洲大象之间的化学交流产生有价值的见解。
Using automated solid-phase dynamic extraction and gas chromatography-mass spectrometry, our search for urinary chemical signals from ovulatory female African elephants (Loxodonta africana) has revealed the bark beetle aggregation pheromones frontalin, exo-brevicomin, and endo-brevicomin, as well as their precursors and the aphid alarm pheromones (E,E)-alpha-farnesene and (E)-beta-farnesene. Enantiomeric ratios for brevicomins have been determined. Prior discovery of common insect/elephant pheromones in Asian elephants, namely, (Z)-7-dodecenyl acetate and frontalin, suggests that the present findings may yield valuable insights into chemical communication among African elephants.
