METHODS AND RESULTS:
The chemical constituents were isolated and purified by various chromatographic techniques indluding silica gel, reverse phase silica gel, sephadex LH-20 and pre-HPLC and identified by their physicochemical properties and spectral data. Sixteen phenolic compounds had been isolated and n-butanol extracts which were fractionated from the ethanol extract of Oplopanax horridus roots bark. Their structures were identified as below, including 7 phenylpropanoid compounds, ferulic acid (1), 3-acetylcaffeic acid (2), caffeic acid (3), homovanillyl alcohol 4-O-beta-D-glucopyranoside (4), 3-hydroxyphenethyl alcohol 4-O-beta-D-glucopyranoside (5), 3, 5-dimethoxycinnamyl alcohol 4-O-beta-D-glucopyranoside (6), and 3-dimethoxycinnamyl alcohol 4-O-beta-D-glucopyranoside (7). Three coumarins, scopoletin (8), esculetin (9) and 3'-angeloyl-4'-acetyl-cis-knellactone (10). And 6 lignan compounds, (+)-isolariciresinol-9'-O-beta-D-glucopyranoside [(+)-Isolariciresinol 9'-O-glucoside ,11], 3, 3'-dimethoxy-4, 9, 9'-trihydroxy-4', 7-epoxy-5', 8-lignan-4, 9-bis-O-beta-D-glucopyranoside (12), (+)-5, 5'-dimethoxylariciresinol 4'-O-beta-D-glucopyranoside (13), (-)-5,5'-dimethoxylariciresinol 4'-O-beta-D-glucopyranoside (14), (-)-pinoresinol 4'-O-beta-D-glucopyranoside (15), and (+)-5, 5'-dimethoxylariciresinol 9'-O-beta-D-glucopyranoside (16).
CONCLUSIONS:
All compounds were isolated and identified for the first time from this plant. All the constituents except compounds 4, 6, 12 and 13 were obtained for the first time from the genus Oplopanax. |
