title: A new 5 alpha,8 alpha-epidioxy sterol from the Okinawan marine sponge of the Axinyssa genus.
abstract: A new sterol (axinysterol) was isolated from the Okinawan marine sponge of the genus Axinyssa. The structure of axinysterol was assigned as 5 alpha,8 alpha-epidioxyergosta- 6,22,25-trien-3 beta-ol based on spectroscopic analysis and chemical transformation.
