00925njm 22002777a 4500 dc Gratacós Cubarsí, Marta author Ribas Agustí, Albert author García Regueiro, José Antonio author Castellari, Massimo author 2010-07 A method for the simultaneous determination of intact glucosinolates and main phenolic compounds (flavonoids and sinapic acid derivatives) in Brassica oleracea L. var. botrytis was proposed. A simplified sample extraction procedure and a UPLC separation were carried out to reduce the total time of analysis. Brassica oleracea samples were added with internal standards (glucotropaeolin and rutin), and extracted with boiling methanol. Crude extracts were evaporated under nitrogen, redissolved in mobile phase and analyzed by UPLC with double detection (ESI--MRM for glucosinolates and flavonoids, and DAD for main sinapic acid derivatives). The proposed method allowed a satisfactory quantification of main native sinapic acid derivatives, flavonoids and glucosinolates with a reduced time of analysis. 0308-8146 doi:10.1016/j.foodchem.2009.11.081 http://hdl.handle.net/20.500.12327/4534 Col Cromatografia Líquida d'Ultra Resolució Glucosinolats Flavonoides Simultaneous Evaluation of Intact Glucosinolates and Phenolic Compounds by UPLC-DAD-MS/MS in Brassica oleracea L. var. botrytis
