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.
