Abstract:
A new cyclopentapeptide dianthin I (1), together with two known ones pseudostellarin A (2) and heterophyllin J (3), was isolated from the aerial parts of Dianthus chinensis. The structure of 1 was elucidated as cyclo-(Gly(1)-L-Phe(2)-L-Pro(3)-L-Ser(4)-L-Phe(5)) on the basis of extensive spectroscopic analyses and chemical methods.
