[Studies on lignin glycosides in root from Ilex pubescens].Zhongguo Zhong Yao Za Zhi. 2007 Jul; 32(13):1303-5.ZZ
To study chemical constituents from Ilex pubescens.
The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral alanlysis.
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).
All of them were isolated from this plant for the first time.
