Abstract
Two new diprenylated indoles, 2′,3′-epoxyasteranthine and 2′,3′-dihydroxyasteranthine, were isolated from the stem bark and the root bark of Asteranthe asterias (Annonaceae). Their structures were elucidated by spectroscopic methods. Each of the two compounds was obtained in an enantiomeric ratio of 3:1 (S/R) and exhibited antimycotic activity against Saprolegnia and Rhizoctonia species.Keywords
