摘要：

Four new okaramine congeners, okaramines J, K, L and M, were isolated from ohara fermented with Penicillium simplicissimum ATCC 90288, together with five biogenetically related compounds, cyclo (8a-(alpha,alpha-dimethylallyl)-L-Trp-8a-(alpha,alpha-dimethylallyl)-L-Trp), cycle (N-8-(alpha,alpha-dimethylallyl)-L-Trp -6a'-(alpha,alpha- dimethylallyl)-L-Trp), cyclo (L-Trp-L-Trp), cycle (6a'-(alpha,alpha-dimethylallyl)-L-Trp-L-Trp), and cycle (N-8(alpha,alpha-dimethylallyl)-L-Trp-L-Trp). Their structures were elucidated on the basis of spectroscopic methods. The new okaramines exhibited no insecticidal activity against silkworms.
