The components of extracts of the repugnatorial glands were identified in the millipede R. padbergi. Hexane extracts of 50 glands were prepared and analyzed by gas cromatography-mass spectrometry (GC-MS). We identified the two main volatile compounds: methyl-1,4-benzoquinone and 3,3a,4,5-tetrahydro-1H-pyrrolo-[2,3-b] pyridine-2,6-dione. The significance of these compounds in the secretion of the repugnatorial glands is discussed.
