Description
Summary:Two new very-long-chain 5-<i>n</i>-alkylresorcinol (AR) homologues, that is, 5-<i>n</i>-nonacosylbenzene-1,3-diol and 5-<i>n</i>-hentriacontylbenzene-1,3-diol, were isolated from acetone extracts of <i>Ailanthus altissima</i> samaras. These phenolic compounds were detected in nearly equal proportions, although their total content varied considerably between samples from urban-grown trees. No correlation was observed between AR levels and the physiological state of the tree, suggesting that environmental conditions may strongly influence AR biosynthesis in <i>A. altissima</i>. Furthermore, the isolated AR mixture exhibited antifungal activity against soil-borne phytopathogens of the genera <i>Fusarium</i> and <i>Rhizoctonia</i>.
