Abstract

From the rice culture of Phomopsis sp. IM 41-1, isolated from the mangrove plant, Rhizhopora mucronata, two dimeric tetrahydroxanthones, phomoxanthone A (1) and 12-O-deacetyl-phomoxanthone A (2) were obtained. Their structures were determined by spectroscopic and spectrometric methods. Both compounds exhibited antimicrobial activities.
