Abstract

New beauverolides L and La were isolated and identified from the entomopathogenic fungi, Beauveria tenella and Paecilomyces fimosoroseus. Their structures, cyclo-[3-hydroxy-4-methyldecanoyl-L-phenylalanyl-L-alanyl-D-leucyl], and cyclo-[3-hydroxy-4-methyldecanoyl-L-phenylalanyl-L-alanyl-D-allo-isoleucyl] were deduced from HPLC and CI-mass spectrometric analyses of their hydrolysates and NMR and mass spectral data.
