Abstract

Four new ferulic acid sucrose esters, β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-2',6'-O-diacetylglucopyranoside (1), β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-2',4'-O-diacetylglucopyranoside (2), β-D-(6-O-trans-feruloyl)fructofuranosyl-a-D-2',4',6'-O-triacetylglucopyranoside (3), β-D-(1-O-acetyl-6-O-trans-feruloyl)fructofuranosyl-a-D-4',6'-O-diacetylglucopyranoside (4), together with four known phenylpropanoids (5–8) were isolated from the rhizome of Sparganium stoloniferum (Graebn.) Buch.-Ham. ex Juz. Their structures were elucidated by chemical evidence and spectral analysis. Compounds 1–8 exhibited obvious inhibitory effects on ADP-induced platelet aggregation.
