| Abstract: | 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. |
