Studies on the Chemical Constituents of Lilium henryi BAKER

Abstract

New bitter phenolic glycosides and a steroid glucoside have been isolated from the fresh bulbs of Lilium Henryi. On the basis of spectroscopic data, chemical evidence and X-ray crystallographic analysis, their structures have been elucidated as (2S)-1-O-p-methoxycinnamoyl-3-O-β-D-glucopyranosylglycerol (methylregaloside A), (2S)-1-O-caffeoyl-3-O-β-D-glucopyranosylglycerol (regaloside C), 3-O-feruloyl-6'-O-(4-O-β-D-glucopyranosylferuloyl)sucrose, and (25R)-3β, 26-dihydroxy-5α-cholestane-6, 22-dione 3-O-β-D-glucopyranoside. Several known components have also been isolated and identified.
