In a previous paper, we reported the structural elucidation of stellarin A, a new cyclic heptapeptide, from the fresh roots of Stellarina yunnanensis Franch. Further chemical study on this plant led to the isolation 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.
在之前的一篇论文中，我们报道了从云南海石竹新鲜根中分离出的一种新的环七肽——海石竹素A的结构解析。对该植物的进一步化学研究导致分离出另外两种新的环肽，命名为海石竹素B和C。通过光谱方法确定它们的结构分别为环（甘氨酸-丝氨酸-异亮氨酸-苯丙氨酸-苯丙氨酸-丙氨酸）和环（甘氨酸-丝氨酸-异亮氨酸-苯丙氨酸-苯丙氨酸-丝氨酸）。
