Abstract: In the previous papers, we have reported the isolation and structural elucidation of seven new cyclopeptides (stellarin A-G). Further chemical study on this plant resulted in the isolation of another new cyclopeptide, namely stellarin H(l). Its structure was established to be cycle (Phe-Ser-Leu-Val-Leu-Pro-Pro-Tyr-Ser) on the basis of the spectral and chemical methods. In adition, a known cyclic pentapeptide, pseudostellarin A, was isolated.
