摘要
Further chemical study on the fresh roots of Stellaria delavayi led to the isolation of another new cyclopeptide, namely stelladelin D. On the basis of spectroscopic analyses and chemical methods, its structure was assigned as cyclo (Gly-Val-Pro-Ser-Pro-Tyr-Phe-Pro-Ala-Ala-Ile) In previous papers((1,2)), we have reported the structural elucidation of three new cyclopeptides named stelladelin A-C from the fresh roots of Stellaria delavayi. Further chemical study on this plant led to the isolation of another new cyclopeptide, namely stelladelin D. In this paper, we shall report its structural elucidation.
