| 摘 要： | In the previous papers,we reported the structural elucidation of stellarins A-E,fivenew cyclopeptides from the fresh roots of Stellaria yunnanensis Franch.Further chemical study on this plant led to the isolation of two other new cyclopeptides named stellarins F(l) and G(2).By a combination of 2D-NMR,enzymatic degradation and FABMS,their structures were established to be cyclo(Gly-Ala-Gly-Ser-Pro-Trp-Phe-Pro) and cyclo(Gly-Ala-Tyr-Leu-Ala),respectively.
