Interpretive Summary: The chemical diversity of the flavones found in 23 species of the plant family Lamiaceae was examined. Among eight species of Salvia examined, 14 different flavones were found. Each species had between two - eight flavones and none of the species had the same mix. One species had no flavones, but instead had a known, but very rare deep red quinone pigment.

Technical Abstract: Several new species and further accessions of the Lamiaceae have been analyzed for their exudate flavonoid profiles. The principle compounds accumulated were flavones and their 6-methoxy derivatives, whereas flavonols were rarely encountered. The chemodiversity observed is relatively low, with only some 15 derivatives being found. The new data are discussed in relation to published data, and chemosystematic aspects are briefly addressed. Of the studied species, Salvia arizonica yielded only a rare diterpene quinone, demethylfruticulin A. Glandular hair diversification and different qualities of their secretions are briefly discussed.
