QUINOLIZIDINE ALKALOIDS AND THE ENZYMATIC SYNTHESIS OF THEIR CINNAMIC AND HYDROXYCINNAMIC ACID ESTERS IN LUPINUS ANGUSTIFOLIUS AND L. LUTEUS

Article abstract of DOI:10.1016/0031-9422(91)84195-X

The accumulation pattern of quinolizidine alkaloids during development of seedings and young plants of Lupinus angustifolius and L. luteus are described.The enzymes catalysing the syntheses of the cinnamic acid O-ester of 13-hydroxylupanine and hydroxycinnamic acid O-esters of lupinine (4-coumaroyl- and feruloyllupinine) are characterized and classified as cinnamoyl-CoA:13-hydroxylupanine O-cinnamoyltransferase (EC 2.3.1.-) and hydroxy cinnamoyl-CoA:lupinine O-hydroxycinnamoyltransferase (EC 2.3.1.-).
