BIOSYNTHESIS OF ANTIRRHINOSIDE IN ANTIRRHINUM MAJUS

Article abstract of DOI:10.1016/0031-9422(92)80017-9

Feeding experiments with deuterium labelled 8-epi-iridodial glucoside, 8-epi-iridotrial glucoside and the corresponding aglucones gave incorporation of all compounds into antirrhinoside in Antirrhinum majus.A higher incorporation of 8-epi-iridotrial than of 8-epi-iridotrial glucoside indicates that the former is an intermediate in the biosynthesis of antirrhinoside although a definite proof could not be obtained.
