Because of their extensive use as botanical dietary supplements, there is increasing interest in the chemical constituents of Hypericum and Echinacea [1]. Although some components of Hypericum species such as hypericin and hyperforin are well known, these species contain many additional bioactive components, including flavones, procyanidins and xanthones [2]. Among the many xanthones found in Hypericum species, euxanthone (1) and 1-methoxy-7- ...
