A New Fructofuranoside from Helwingia chinensis (Cornaceae)

A new fructofuranoside, together with ten known compounds were isolated from the EtOH extraction of the aerial part of Helwingia chinensis . Their structures were elucidated to be 2 - O-(E) - caffeoyl-3- O -( 3, 5-dimethoxylcoumaroyl )- α-D-fructofuranose ( 1 ), 2- O -β-D-fructofuranosyl-α-D-allopyranose ( 2), liquiritigenin (3 ), 4′-hydroxy-2, 3-dihydro-flavonone-7- O -β-D-glucoside ( 4), daidzin (5 ), apigenin 5- O -glucopyranoside ( 6 ), apigenin-7- O -β-D-glucoside ( 7 ), coumaric acid 4- O -β-D-glucopyranoside ( 8), glucopyranosylcaffeic acid (9 ), 3β-hydroxyglutin-5-ene ( 10 ), diosgenin 3- O -α-L-rhamnopyranosyl (1→2 )-[α -L-arabinofuranosyl(1→ 3)]- β-D-glucopyranoside ( 11 ) by intensive interpretation of spectral data.
