The structure of a new secoiridoid glucoside, sambacolignoside (1), which had been isolated from Jasminum sambac (L.) Ait. together with seven new oligomeric iridoid glucosides and oleoside 11-methyl ester (2), was elucidated as 7-O- [(+) -1-hydroxypinoresinol-β-D-glucoside- (7-6′ ″)] -oleoside 11-methyl ester. This is the first example of a lignan linked secoiridoid glucoside.
