Abstract
In addition to the known iridoid glucosides antirrhinoside (1), antirr hide (3), linarioside (5) and chaenorrhinoside (6), a novel nonglucosi dic iridoid lactone was isolated in trace amount from Antirrhinum maju s (Scrophulariaceae). This lactone, named antirrhinolide (4a) was synt hesised from 5,6-O-isopropylidene-dihydroantirrhinoside aglucone (7) i n two steps. Thus, its absolute stereochemistry was proven unequivocal ly.
