Abstract

A new antifungal iridoid compound, together with three active known iridoids, galioside, galioside aglucone, and apodanthoside, as well as 3-O-β-D-glucopyranosyl-28-O-β-D-glucopyranosyl quinovic acid and quercetin-3-O-methyl-3-O-β-D-rhamnopyranoside, were isolated from the stems of Tocoyena formosa. This new compound was characterized by spectral data as 11-O-transferuloylteucrein.
