Two new cyclopeptides, named arenariphilin A ( 1 ) and arenariphilin B ( 2 ), were isolated from the whole plants of Arenaria oreophila. Their structures were determined as cyclo‐(Thr‐Gly) ( 1 ) and cyclo‐(Ser 1 ‐Gly ‐Ser 2 ‐Ile ‐Phe 1 ‐Phe 2 ) ( 2 ) on the basis of spectral data, especially by 2D‐NMR.
