Data set on hydroxycinnamic acid ester analysis from the cell walls of apples and grapes

Abstract : Data on the esters of hydroxycinnamic acids (HCAs) from the cell walls of wine grapes (Cabernet franc) and cider apples (Douce Moen and Guillevic) were acquired. Caffeic acid, p-coumaric acid (pCA) and ferulic acid (FA) monomers were identified by HPLC-UV/MS. Means to limit the oxidative degradation during cell wall preparation were assessed by the yield of HCA recovered after alkaline extraction. Following the optimum cell wall preparation, the pCA content varied between 2.3 and 32.5 mg kg(-1) dry cell wall and that of FA varied between 0.3 and 17.2 mg kg(-1) dry cell wall. Higher HCA quantities were found in the peels compared to the flesh and in apples compared to grapes. The Douce Moen apple was richer in HCAs than the Guillevic apple. pCA was localized in the cell wall as observed by TEM after labeling with the INRA-COU1 antibody that recognizes pCA linked to O-5 of arabinose. The anti-FerAra antibody targeting FA on O-5 of arabinose failed to locate FA esters in the apple and grape cell walls.
