A new caffeoyl glycoside of 3, 4-dihydroxy-β-phenethyl alcohol, designated as forsythiaside (1), was isolated from the fruits of Forsythia suspensa VAHL (Oleaceae). The structure of 1 is proposed to be 3, 4-dihydroxy-β-phenethyl-O-α-L-rhamnopyranosyl-(1→6)-4-O-caffeoyl-β-D-glucopyranside on the basis of analysis of the carbon-13 nuclear magnetic resonance spectrum.
