Methoxyflavone aglycones were isolated from the leaf surface of Mentha suaveolens and M. pulegium. 5,7-Dihydroxy-6-methoxy- and 5,6-dihydroxy-7-methoxyflavones with a substituted B-ring and 5,6-dihydroxy-7,8-dimethoxyflavones, characteristic flavonoid constituents of the subfamily Nepetoideae and of the tribe Saturejeae, respectively, were observed in both species. Mentha suaveolens showed considerable chemical variation between samples from Spain and Algeria. (C) 1998 Elsevier Science Ltd. All rights reserved.
