Two New Cyclic Peptides from Drymaria diandra

Abstract

Two new cyclic peptides, drymarins A and B, were isolated from the whole plants of Drymaria diandra B1. Their structures were determined by detailed spectroscopic analysis as cyclo(-Phe₁-Pro₁-Pro₂-Pro₃-Phe₂-Phe₃-Val-Ile-Ala-) and cyclo (-Pro₁-Phe-Tyr-Pro₂-Gly-Leu-).
