Russujaponols g-L, Illudoid sesquiterpenes, and their neurite outgrowth promoting activity from the fruit body of russula japonica

摘要

Six new illudoid sesquiterpene, russujaponols G-L (1-6) were isolated from the fruit bodies of Russula japonica. Their structures were established primarily by 2D NMR experiments. Furthermore, russujaponols I-K showed neurite outgrowth promoting activity in the primary cultured rat cortical neurons.
