New sucrose phenylpropanoid esters from Polygonum perfoliatum.

Five diferuloyl esters of sucrose, 6'-acetyl-3,6-diferuloylsucrose (helonioside B) (1); 2',4',6'-triacetyl-3,6-diferuloylsucrose (2); 1, 2',4',6'-tetraacetyl-3,6-diferuloylsucro se (3); 1,2',6'-triacetyl-3, 6-diferuloylsucrose (4); and 2',6'-diacetyl-3,6-diferuloylsucrose (5), were isolated, along with the 1,3,6-tri-p-coumaroyl-6'-feruloylsucroses, vanicoside A and vanicoside B, from the whole plant of Polygonum perfoliatum by various chromatographic methods. The structures of these phenylpropanoid glycosides were determined on the basis of their NMR and mass spectroscopic data. Compound 1 is a known compound, but 2-5 are new members of this class.
