Abstract
The flavonoid aglycones excreted by aerial parts of three Viguiera spe cies have been analyzed. One of them is a rare natural product. So far unpublished NMR data are reported for three flavones. Each species of V. section Hypargyrea exhibits a distinctive flavonoid profile based on different patterns of methoxylation, but the taxonomic section as a whole is not characaterized by any distinctive characters of its flav onoid chemistry.
