Abstract
Twenty five known aromatic glycosides (1-25) and three known sesquiterpene glycosides (26-28) have been isolated from the twigs of Litsea cubeba by using various chromatographic techniques. Their structures were identified by spectroscopic data analysis (MS, IR, 1D and 2D NMR) as (7S,8R)-dehydrodiconiferyl alcohol 4,9′-di-O-β-D-glucopyranoside(1),(7S,8R)-5-methoxydihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside(2), (7S,8R)-urolignoside(3), (7R,8S)-dihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside(4), saposide B(5), lanicepside A(6), matairesinol-4-O-β-D-glucopyranoside (7), tyraxjaponoside B(8), (+)-lyoniresinol-9′-O-β-D-glucopyranoside (9), alaschanisoside A (10), syringin (11), psoralenoside (12), isopsoralenoside (13), scopolin(14), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (15), 3-hydroxy-4,5-dimethoxyphenyl-β-D-glucopyranoside (16), 2-(3,4-dihydroxyphenyl)ethyl-β-D-glucopyrnoside (17), 2-(4-dihydroxyphenyl)ethyl-β-D-glucopyranoside (18), (+)-catechin-7-O-β-D-glucopyranoside (19), 3′-O-methylepicatechin-7-O-β-D-glucopyranoside (20), kaempferitrin (21), quercetin-3-O-α-L-rhamnopyranside (22), kaempferol-3-O-β-D-glucopyranoside (23), kaempferol 3-O-β-D-glucopyranosyl(1→2)-O-β-D-galactopyr anoside-7-O-α-L-rhamnopyranoside (24), quercetin 3-O-α-L-rhamnopyranosyl(1→6)-O-β-D-glucopyranosyl(1→3)-O-α-L-rhamnopyranosyl(1→2)-O-β-D-glucopyranoside (25), staphylionoside D(26), vomifoliol 9-O-β-D-glucopyranoside (27), dihydrovomifoliol-O-β-D-glucopyranoside (28). Compounds 1-21 and 24-28 were obtained from this genus for the first time.
