Article abstract of DOI:10.1016/0031-9422(88)83118-2

Novel acylated glycerol glucosides, regaloside A and B, both bitter to the taste, have been isolated from the fresh bulbs of Lilium regale.Their structures have been shown by the spectral and chemical evidence to be (2S)-1-O-p-coumaroyl-3-O-β-D-glucopyranosylglycerol and (2S)-1-O-p-coumaroyl-2-O-β-D-glucopyranosyl-3-O-acetylglycerol, respectively.Key Word Index - Lilium regale; Liliaceae; acylated glycerol glucosides; p-coumaric acid esters; regaloside A; regaloside B; bitter principles; stereochemistry.
