Bio-oxidative cleavage of carotenoids: important route to physiological active plant constituents
1992
Lutz, Arthur | Winterhalter, P.
The beta-D-glucosides of (4R,1'F,3'E)-4-(5'-hydroxy-3'-methyl-1',3'-pentadienyl)-3, 5,5-trimethyl-2-cyclohexen-1-one 7 as well as of trans-abscisic alcohol (ABA-alcohol) 8 have been isolated and characterized in quince fruit through spectral and chemical studies ABA-alcohol 8 has recently been found to be involved in the biosynthesis of the important plant hormone abscisic acid (ABA) 9, the latter compound being also present in a still non-specified glycosidically bound in quince fruit. Based on the finding of these new fifteen carbon (C15) constituents in quince, biodegradation of carotenoids is discussed.
