Highly oxygenated chromones from mangrove-derived endophytic fungus Rhytidhysteron rufulum

Five highly oxygenated chromones, rhytidchromones A-E, were isolated from the culture broth of a mangrove-derived endophytic fungus, Rhytidhysteron rufulum. Their structures were mainly determined by analysis of NMR spectroscopic data. Their cytotoxicities against human cancer cell lines were reported.87
