Two normonoterpenes were detected from an unidentified Tyreophagus sp. as new female-specific components. Both planar structures were identified to be 2,6-dimethyl-5-heptenal (1) and 2,6-dimethyl-5-hepten-1-ol (2) by GC/MS co-chromatography with synthetic 1 and 2. The stereochemistry of 2 was determined to be R by a GC analysis with a chiral column, while that of 1 was presumed to be similar to 2 based on the biosynthetic aspects.
从一种身份不明的 Tyreophagus sp.中检测到两种常萜烯类化合物,它们是新的雌性特异性成分。通过与合成物 1 和 2 的气相色谱/质谱联用,确定这两种平面结构分别为
2,6-二甲基-5-庚烯醛(1)和
2,6-二甲基-5-庚烯-1-醇(2)。通过使用手性色谱柱进行气相
色谱分析,确定 2 的立体
化学结构为 R,而根据
生物合成方面的推测,1 的立体
化学结构与 2 相似。
