✦ Synopsis

Previously, T. Sakan and coworkers' reported that the active principle of the neutral fraction of Actinidiapolygsma for Felidce onixals is matatabilactone which was identified as a mixture of iridoqrmecin (I) and isoiridcmyrmecin (II).

In connection with a thorough investigation of the terpenes of Actinidia polygsma, we have reexamined the la&one part of Actinidia polygama argl the terpenes of Neneta cataria.

Prom the leaves and galls of Actinidia polygama we have isolated, in addition to iridomgrmecin and isoiridcanyrmecin, three new lactones (dihydronepetalactone (III), isodihydronepetalactone (IV) and neonepetalactone (V)), which have been found to be quite attractive to czts. In addition, the 3 absence of ismeric iridolactones and dihydronepetalcc',ones has been deno+ &rated by vapor phase chrcmatographic analysis. The isolzticn of these lactones was accomplished by repeated column chromato&x& on silicic acid of the la&one fraction, obtained by alkaline hydroly:.
