pubmed-article:5917086 | pubmed:abstractText | Two crystalline components isolated from the defensive secretion of the glomerid millipede, Glomeris marginata, are identified as 1- methyl- 2- ethyl- 4( 3H)- quinazolinone and 1,2- dimethyl- 4( 3H)- quinazolinone. These heterocyclic compounds bear a close structural resemblance to arborine, the chief alkaloid of the Indian medicinal plant, Glycomis arborea Correa. | lld:pubmed |
