从石竹科植物金铁锁 Psammosilene tunicoides中分离得到 2个环二肽及由 2个环二肽组成的混合物。它们的结构经光谱鉴定为环 (丙 -丙 ) ( )、环 (丙 -缬 ) ( )、环 (丙 -亮 ) ( )和环 (丙 -异亮 ) ( )。它们均为新的天然产物。
Two cyclic dipeptides and a mixture of two cyclic dipeptides were isolated from the carnation Psammosilene tunicoides. Their structure was identified by the spectrum of the ring (propyl-propyl) (), ring (c-) (), ring (c-bright) () and ring (c-bright) (). They are all new natural products.
