Three new compounds from the leaves of Liquidambar formosana.
Two new flavan glycosides, (2S)-5,7,4'-trihydroxyflavan-7-O-β-D-glucopyranoside and (2S)-5,7,4'-trihydroxyflavan-5-O-β-D-glucopyranoside, and a new neolignan, (7S,8S)-3-methoxyl-3'-O-β-D-glucopyrannosyl-4':8,5':7-diepoxyneolignan-4,9'-diol, were isolated from the leaves of Liquidambar formosana Hance. Their structures were elucidated on the basis of spectroscopic data and chemical evidence.
