Precursors of Damascenone in Fruit Juices

Skouroumounis, George K.,Massy-Westropp, Ralph A.,Sefton, Mark A.,Williams, Patrick J.

, p. 3533 - 3536 (1992)

The acid-catalysed reactions of 6,7-megastigmadiene-3,5,9-triol and the β-D-glucosides of 5-megastigmen-7-yne-3,9-diol and 3-hydroxy-β-damascenone have been studied in relation to the formation of damascenone.The results show that hydrolysis of the allene triol could account for damascenone formation in the juices of grapes and other fruits.
