In a previous paper, we reported the structural elucidation of stellar
in A, a new cyclic heptapeptide, from the fresh roots of Stellarina yu
nnanensis Franch. Further chemical study on this plant led to the isol
ation of another two new cyclopeptides named stellarin B and C. Their
structures were established to be cyclo(Gly-Ser-HOIle-Phe-Phe-Ala) and
cyclo(Gly-Ser-HOIle-Phe-Phe-Ser), respectively, by spectral methods.
