Pyrone glycosides from Acosmium panamense (Benth.) Yacovlev.
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.
