In addition to 3,4-dihydroxybenzoic acid and (-)-epicatechin, a new glycoside of the latter has been isolated from the methanolic extract of the stem bark of Brosimopsis acutifolium. Its structure was established to be (- )-epicatechin 5-O-β-D-xylopyranoside on the basis of spectroscopic and chemical methods.
