Objective To study the chemical constituents from the roots of Sambucus williamsii. Methods Silica gel, ODS, and preparative HPLC were used to isolate the compounds. Their chemical structures were elucidated on the basis of spectral data. Results Eighteen compounds were isolated, and they were identified as 7α-O-ethylmorroniside (1), 7β-O-ethylmorroniside (2), dehydromorroniside (3), loganin (4), 7-dehydrologanin (5), 7-formyloysecologanin (6), sweroside (7), coniferyl alcohol 9-O-β-D-glucopyranoside (8), 3-methoxy-4-(2-glycerol)-phenylpropanol (9), (7R, 8R)-7, 8-dihydro-9'-hydroxyl-3'-methoxyl-8- hydroxymethyl-7-(4-hydroxyl-3-methoxyphenyl)-1'-benzofuranpropanol-9'-O-β-D-glucopyranoside (10), (7R, 8R)-4, 7, 9, 9'- tetrahydroxy-3-methoxy-8-O-4'- neoligan-3'-O-β-D-glucopyranoside (threo) (11), (7R, 8R)-3-methoxy-8, 4'-oxyneoligna-3', 4, 7, 9, 9'- pentol (threo) (12), 5-(1'-hydroxyethyl)-methyl nicotinate (13), 3-(hydroxyacetyl) indole (14), 4'-hydroxy-N-(4-hydroxy-3- methoxybenzoyl)-3', 5'-dimethoxybenzamide (15), 3-methoxyl-1H-pyrrole (16), (1S, 3S)-1-methyl-1, 2, 3, 4-tetrahydro-β-carboline-3- carboxylic acid (17), and syringic acid-4-O-α-L-rhamnopyranoside (18). Conclusion Compounds 8—10 and 13—17 are firstly isolated from the plants in Caprofoliaceae, and furthermore, compounds 1—4, 6, 11, and 18 are isolated from the plants of Sambucus L. for the first time.
