New Phenylpropanoid Glycerol Glucosides from the Bulbs of Lilium Species

概要

論文の詳細を見る
The fresh bulbs of the genus Lilium have yielded new phenylpropanoid glycerol glucosides, epiregaloside A (6b), epi-regaloside C (7b) and epi-regaloside F (10b), as mixtures with the corresponding (2S)-regalosides (6a, 7a and 10a), and regaloside G (11). Compounds 6b and 7b have been obtained from Lilium pardarinum, and 6b, 10b and 11 from L. auratum. The spectroscopic data and chemical evidence have allowed us to assign the structures of 6b, 7b, 10b and 11 as (2R)-1-O-p-coumaroyl-3-O-β-D-glucopyranosylglycerol, (2R)-1-O-caffeoyl-3-O-β-D-glucopyranosylglycerol, (2R)-1-O-feruloyl-3-O-β-D-glucopyranosylglycerol and (2S)-1-O-feruloyl-2-β-D-glucopyranosylglycerol, respectively. In addition, jatropham and its glucoside have been detected in the fresh bulbs of L. medeoloides. Several previously reported compounds have also been obtained and identified.
