| Abstract: | One new iridoid glucoside, 4″‐O‐β‐D ‐glucosyl‐6′‐O‐(4‐O‐β‐D ‐glucosylcaffeoyl)linearoside ( 1 ), and two new secoiridoid glucosides, 6′‐O‐acetylsweroside ( 2 ) and 6′‐O‐acetyl‐3′‐O‐3‐(β‐D ‐glucopyranosyloxy)‐2‐hydroxybenzoyl]sweroside ( 3 ), were isolated from the dried roots of Gentiana manshurica (Gentianaceae), together with 11 known ones, including one iridoid glucoside, five secoiridoid glucosides, and five triterpenes. The structures of the new compounds were determined on the basis of detailed spectroscopic analyses and acidic hydrolysis. |
