Abstract:
Besides caffeic acid three pyrones have been isolated from aquous bark extracts from Acosmium panamense and their structures were determined using spectroscopical methods. Besides the already described desmethylyangonine its O4'-mono as well as the di(1-6)glucoside are found the first time.
