Abstract

Three novel cyclic peptides, named yunnanins D [I: cycle(-Gly-Ile-Ser-Phe-Arg-Phe-Pro-)], E [2: cycle(-Gly-Ser-6-Hydroxy Ile-Phe-Phe-Ser-)] and F [3: cycle(-Gly-Val-Thr-Trp-Tyr-Pro-Ser-Ser-1, have been isolated from Stellaria yunnanensis (Caryophyllaceae) and their structures were elucidated by spectroscopic evidence and chemical degradation.
