[Studies on lignin glycosides in root from Ilex pubescens].
OBJECTIVE
To study chemical constituents from Ilex pubescens.


METHODS
The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral alanlysis.


RESULTS
Six lignin glycosides were identified as (7S, 8R) dihydrodehydrodiconiferyl alcohol 4-O-beta-D-glucopyranoside (1), (-)-olivil-4'-O-beta-D-glucopyranoside (2), (7S, 8R) dehydrodiconiferyl alcohol 4-O-beta-D-gluco-pyranosid (3), (+)-cyclo-olivil 6-O-p-D-glucopyranoside (4), (+)-medioresinol di-O-beta-D-glucopyranoside (5), (+)-pinoresinol-4, 4'-O-bisglucopyranoside (6).


CONCLUSIONS
All of them were isolated from this plant for the first time.
