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 anal- ysis (MS, IR, 1D and 2D NMR) as (7S,8R)-dehydrodiconiferyl alcohol 4,9'-di-O-β-D-glucopyranoside(1), (7S,8R)-5-methoxydi- hydrodehydrodiconiferyl 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-glucopyr- anoside ( 16 ), 2-( 3,4-dihydroxyphenyl ) ethyl-β-D-glucopyrnoside ( 17 ), 2-( 4-dihydroxyphenyl ) ethyl-/β-D-giucopyranoside ( 18 ),( + ) -catechin-7-O-β-D-glucopyranoside (19) , 3 '-O-methylepicatechin-7-O-β-D-glucopyranoside (20) , kaempferitrin (21), querce- tin-3-O-α-L-rhamnopyranside ( 22 ), kaempferol-3-O-β-D-glueopyranoside ( 23 ), kaempferol 3-O-β-D-glueopyranosyl ( 1→2 ) -O-β-D- galactopyr anoside-7-O-α-L-rhamnopyranoside ( 24 ), quereetin 3-O-α-L-rhamnopyranosyl ( 1 --r6 ) -O-β-D-glueopyranosyl ( 1→3 ) -O-α- L-rhamnopyranosyl ( 1 --* 2 ) -O-β-D-glueopyranoside ( 25 ), staphylionoside D ( 26 ), vomifoliol 9-O-β-D-glucopyranoside ( 27 ), dihydrovomifoliol-O-β-D-glucopyranoside (28).
