Coumarins of Loricaria ferruginea

ABSTRACT In the presented research we isolated and characterized compounds from Loricaria ferruginea (Ruiz & Pav.) Wedd., Asteraceae. To the best of our knowledge no data on any compounds from L. ferruginea have been published to this day. As main compounds of the hexane extract we found four known coumarins: 5,7-dimethoxycoumarin; 5,7,8-trimethoxycoumarin; 5-hydroxyobliquine and 5-methoxyobliquine. All the structures were determined by spectroscopic and spectrometric methods.
