In addition to a known caffeoyl glycoside of 3,4-dihydroxyphenethyl alcohol, acteoside (1), a new caffeoyl glycoside of β,3,4-trihydroxyphenethyl alcohol, designated as β-hydroxyacteoside (2), was isolated from the fruits of Forsythia viridissima LINDLEY (Oleaceae).The structure of 2 was established as β,3,4-trihydroxyphenethyl-O-α-L-rhamnopyranosyl-(1->3)-4-O-caffeoyl-β-D-glucopyranoside on the basis of analysis of the carbon-13 nuclear magnetic resonance spectrum and chemical evidence.Keywords - Forsythia viridissima; Oleaceae; acteoside; caffeoyl glycoside of β,3,4-trihydroxyphenethyl alcohol; β-hydroxyacteoside; 13C-NMR spect ra
