摘要

A new guibourtinidol glycoside, (2R,3S)-guibourtinidol-3-O-alpha-D-apiofuranosyl-(1 -> 6)-O-beta-D-glucopyranoside (1), and three known compounds, quercetin 7-O-beta-D-glucopyranoside (2), syringaresinol-4-O-beta-D-glucopyranoside (3) and dehydrodico-niferyl alcohol 4,9'-di-O-3-D-glucopyranoside (4), were isolated from the root bark of Morus alba L. through repeated silica gel, octadecyl silica gel and Sephadex LH-20 column chromatography for the n-BuOH fraction. The chemical structure of the compounds was elucidated based on MS, infrared, 1 D and 2D NMR spectroscopic data. Compounds 2-4 were also isolated for the first time from the root bark of M. alba L. in this study.
