A colourless amorphous solid was obtained by silica gel column chromatography, sephadex LH-20 and PHPLC from the rhizomes of Sparganium stoloniferum. The results of spectroscopic analysis showed that the sample was the mixture of two cis-trans isomers:β-D-(1-O-acetyl-3-O-cis-feruloyl)fructofuranosyl α-D-2′,4′,6′-O-triacetylglucopyranoside (1) and β-D-(1-O-acetyl-3-O-trans-feruloyl) fructofuranosyl α-D-2′, 4′, 6′-O-triacetylglucopyranoside ( 2 ) at the ratio of 1 : 4. In addition, one phenylpropanoid glycerol, i. e. 1-O-feruloyl-3-O-p-coumaroylglycerol ( 3 ) was also isolated from this plant. Among them, compound 1 is a new sucrose esters.
