| China Journal of Chinese Materia Medica, 2007, 32(16):1656-9. | | Studies on chemical constituents in fresh fleshy scaleleaf of Lilium lancifolium.[Pubmed: 18027661] | To study the chemical constituents in fresh fleshyscaleaf of Lilium lancifolium.
METHODS AND RESULTS:
The constituents were separated. by various kinds of chromatography and their structures were identified on the basis of spectral analysis. Ten compounds were identified regaloside A (1), Regaloside C (2), methyl-a-D-mannopyranosid (3), methyl-ca-D-glucopyranoside (4), (25R, 26R) -26-methoxyspirost-5-ene-3p-yl-O-ca-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (5), (25R)-spirost-5-ene-3beta-yl-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside (6), (25R, 26R)-17alpha-hydroxy-26-methoxyspirost-5-ene-3beta-yl-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyra nosyl-(1-->6)]-beta-D-glucopyranoside (7), daucosterol (8), adenoside (9), berberine (10).
CONCLUSIONS:
All compounds except 1 and 3 were isolated from this species for the first time, and berberine was first reported in genus Lilium. | | Chemical and Pharmaceutical Bulletin, 2008, 36(7):2430-2446. | | Studies on the chemical constituents of Lilium henryi BAKER.[Reference: WebLink] | New bitter phenolic glycosides and a steroid glucoside have been isolated from the fresh bulbs of Lilium Henryi.
METHODS AND RESULTS:
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.
CONCLUSIONS:
Several known components have also been isolated and identified. |
