Abstract

Three novel cyclic pentapeptides, named astins F (1), G (2) and H (3), which two of them contain one chlorine atom, have been isolated from Aster tataricus (Compositae) and their structures were elucidated by spectroscopic evidence, chemical degradation and chemical transformation from astin C to 2.
