摘要：

A recently introduced hydrophilic end-capped C18 column (YMC ODS-AQ) was tested for the analysis of the nonvolatile organic acids in orange juices. Ten carboxylic acids can be detected from Valencia orange juice by isocratic elution with 20 mM KH2PO4 as the mobile phase with a flow rate of 0.7 mL/min and UV detection at 214 nm. Juice samples are purified through a disposable SCX (benzenesulfonylpropyl) extraction cartridge.
