Abstract
Three hydroxylasiodiplodins were isolated from the mycelium extracts of Lasiodiplodia theobromae IFO 31059; and their structures were identified as (3R),(4S)-4-hydroxylasiodiplodin, (3R),(6R)-6-hydroxy-de-O-methyllasiodiplodin and (3R),(5R)-5-hydroxy-de-O-methyllasiodiplodin. All showed potato micro-tuber inducing activity.
