Abstract
Hydroxycinnamoyltransferase activities which catalyze the formation of O-hydroxycinnamoyl- (p-coumaroyl-, feruloyl-, and sinapoyl-)-glucaric acids via the corresponding 1-O-hydroxycinnamoyl- β-glucoses, and O-(p-coumaroyl)-quinic acid and O-(p-coumaroyl)-shikimic acid both via p-coumaroyl-CoA thioester have been isolated from leaves of Cestrum elegáns D. F. L. v. Schlechtendal. The enzymic activities involved could be classified as 1-O-hydroxycinnamoyl-βglucose : glucaric acid hydroxycinnamoyltransferase (EC 2.3.1.- ) and p-coumaroyl-CoA : quinic acid/shikimic acid hydroxycinnamoyltransferase (EC 2.3.1. - ). This is the first time that both the O-glucoside- and the S-CoA-dependent activities in phenolic acid-ester formation were found to be present in the same plant
