Novel phenolic glycosides, adenophorasides A-E, from Adenophora roots.
Five novel phenolic glycosides, adenophorasides A (1), B (2), C (3), D (4), and E (5), were isolated from commercial Adenophora roots, together with vanilloloside (6), 3,4-dimethoxybenzyl alcohol 7-O-beta-D: -glucopyranoside (7), and lobetyolin (8). The structures of the new compounds (1-5) were characterized as 4-hydroxy-3-methoxyphenylacetonitrile 4-O-beta-D: -glucopyranoside (1), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (2), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-alpha-L: -rhamnopyranosyl-(1-->6)-beta-D: -glucopyranoside (3), 4-hydroxyphenylacetonitrile 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (4), and 4-hydroxy-3-methoxybenzyl alcohol 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (5), respectively, by means of spectroscopic and chemical analyses.
