Two new sucrose esters from Sparganium stoloniferum

Two new sucrose esters, beta-D-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosyl-alpha-D-2',4',6'-O-triacetylglucopyranoside (1) and beta-D-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosyl-alpha-D-2',3',6'-O-triacetylglucopyranoside (2), together with two known sucrose esters have been isolated from Sparganium stoloniferum. Their structures were elucidated by spectroscopic methods.
