摘要
从石竹科植物多荚草 (Polycarponprostratum (Forssk .)Aschers.etSchwein .exAschers)中分离得到 2个新的环肽化合物polycarponinB和C (1,2 )。它们的结构通过波谱方法分别鉴定为 :cyclo(_Gly1_Ile_Val1_Leu1_Val2 _Gly2 _Leu2 _Pro)和cyclo(_Pro1_Thr_Leu1_Pro2 _Pro3_Val_Leu2 _Phe)。
Two new cyclic peptides, polycarponin B and C (1, 2), were isolated from the whole plants of Polycarpon prostratum (Forssk.) Aschers. et Schwein. ex Aschers. By detailed spectroscopic analysis, their structures were determined as cyclo(-Gly(1)-Ile-Val(1)-Leu(1)-Val(2)-Gly(2)-Leu(2)-Pro) and cyclo(-Pro(1)-Thr-Leu(1)-Pro(2)-Pro(3)-Val-Leu(2)-Phe), respectively.
