Abstract From whole plants of Linaria japonica , four iridoid esters of d -glucopyranose were isolated. Iridolinaroside A is an iridoid ester on the 1-position of β- d -glucopyranose, while iridolinarosides B-D are esters between two units of the same iridoid moiety and one molecule of d -glucopyranose. Since two iridoid moieties were esterified onto non-anomeric hydroxyl groups, iridolinarosides B-D
