Abstract:
A new compound was isolated from the water-soluble fraction of a methyl alcohol extract obtained from the larva of the dobsonfly (Protohermes grandis Thunberg). The novel compound had a 12-membered ring and was confirmed to be a cyclic dipeptide of D-ornithine by a chiral analysis, using high-performance liquid chromatography, 2D-nuclear magnetic resonance, and field desorption mass spectrometry.
