文摘Further chemical study on Stellaria delavayi led to the isolation of two ether new cyclopeptides, namely stelladelin B and C. On the basis of spectroscopic analysis and chemical evidence, their structures were established as cyclo(Gly-Ile-Pro(2)-Pro(1)-Ala-Tyr-Asp-Leu) and cylo(Val-Pro(3)-Tyr(2)-Pro(2)-Pro(1)-Phe-Tyr(1)-Ser), respectively.
