Two new cyclic depsipeptides, 5-OHKF (1) and norKA (2), together with the known congeners kahalalideF (3) and isokahalalide F ((4S)- methylhexanoic kahalalideF) (4) were isolated from the greenalgaBryopsis pennata. The structures of the new compounds were established on the basis of extensive 1D and 2D NMR spectroscopic analysis and mass spectrometric (ESIMS) data. The absolute configuration of
