 Title    Flavonoid Aglycones from the Leaf Surfaces of Some Artemisia spp. (Com positae-Anthem ideae)  
 Abstract    Several species of the large genus Artemisia have been analysed for the flavonoid aglycone composition of their leaf exudates. These species belong to different taxonomic groups within Artemisia. Flavone and flavonol aglycones were found as the major flavonoid constituents of the leaf exudates. Many of these compounds were 6-methoxylated, with additional substitu­ tions at the 7-, 3'-and 4'-position of the molecule. In addition, 7,4'-substituted apigenin and luteolin derivatives and rarely also coumarin derivatives were encountered in some species. The observed substitution trends are in accordance with literature data. Taxonomic and eco­ logical aspects are briefly discussed.
