千足虫（双足类）以其有毒或驱避的防御分泌物而闻名。作为一个更大的调查的一部分，我们描述了7属14种塔斯马尼亚千足虫的化学成分。在Gasterogramma属中发现了6种产生无环酮，包括刺激性的不饱和酮1、2和6，以及新型的(rel-3R,5S,7S)-3,5,7-三甲基-2,8-癸二酮（7b），其立体构型是通过对异构体的立体选择合成建立的。这些化合物以前没有在千足虫的防御分泌物中检测到。本文首次报道了在南半球温带地区土壤和凋落物动物群中占主导地位的大叶蝉亚目（多叶蝉亚目）。
Millipedes (Diplopoda) are well known for their toxic or repellent defensive secretions. As part of a larger investigation, we describe the chemical constituents of 14 species of Tasmanian millipedes in seven genera. Six species in the genus Gasterogramma were found to produce acyclic ketones, including the pungent unsaturated ketones 1, 2, and 6, and the novel (rel-3R,5S,7S)-3,5,7-trimethyl-2,8-decanedione (7b), for which the stereoconfiguration was established by stereoselective syntheses of pairs of isomers. These compounds have not been detected before in millipede defensive secretions. This report is the first on species of the suborder Dalodesmidea (Polydesmida), a dominant component of the soil and litter fauna of the temperate regions of the Southern Hemisphere.
