GRAPHICAL ABSTRACT
ABSTRACT
A new phenanthrene derivative and a new phenylethanoid glycoside were isolated from Forsythia suspensa (Thunb.) Vahl leaves, named as 5,6-dimethoxy-9,10-dihydrophenanthrene- 1,2,7-triol (1), phenethyl alcohol 8-O-α-L-rhamnopyranosyl-(1→3)-O-β-D- glucopyranosyl-(1→4)-O-β-D-glucopyranoside (2). These structures were determined by analysing their physical and chemical properties and using high-resolution mass spectrometry, infrared spectroscopy, nuclear magnetic resonance and other spectroscopic techniques. In addition, the toxic activity of the isolated compounds on RAW 264.7 cells was evaluated, but the isolated compounds did not show significant activity.
