Abstract
A novel cyclic depsipeptide, enniatin G, together with enniatins B and B sub(4) were isolated from the mangrove fungus Halosarpheia sp.(strain 732) from the South China Sea. Their structures were determined by analysis of spectroscopic data, mainly two-dimensional nuclear magnetic resonance experiments. Enniatin G exhibited activity against Heps 7402, ED sub(50) 12mg/mL.
