One hydroxyeugenol and five coniferyl alcohol derivatives have been isolated from the roots of Cosmos caudatus. Structures of the isolated compounds were established on the basis of spectral data. Z-coniferyl alcohol 3'-acetyl-4-isobutyrate and 1',2'-dihydroxy-coniferyl alcohol-3'-isobutyryl-4-isobutyrate are new natural compounds. The other compounds, 1'-acetoxy-eugenol-4-isobutyrate, 1',2'-epoxy-Z-coniferyl alcohol-3'-(2-methylbutyryl)-4-isobutyrate, 1',2'-epoxy-Z-coniferyl alcohol-3'-acetyl-4-isobutyrate and 1',2'-epoxy-Z-coniferyl alcohol-3'-isobutyryl-4-isobutyrate, have been described from species of the same tribe (Heliantheae), but their antifungal properties are reported here for the first time.
