title: Two cyclohexenone glycosides from the North American fern Woodwardia virginica (L.) Smith.
abstract: New glycosides having multisubstituted cyclohex-2-enones as aglycones and saccharide moieties consisting of three and four glucoses, respectively were isolated from the ethanol extract of the American fern Woodwardia virginica. The structures were elucidated using extensive spectroscopic analysis (1D and 2D NMR, MS, IR, CD and UV) including determination of absolute stereochemistry by chemical methods.
