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.
从多臂蝇幼虫(Protohermes grandis Thunberg)甲醇提取物的水溶性部分中分离出了一种新化合物。通过使用高效液相色谱法、二维核磁共振法和场解吸质谱法进行手性分析,证实这种新型化合物具有一个 12 元环,是 d-ornithine 的环状二肽。
