An off-line 2D-HPLC method was employed to achieve enantiomeric separation of amino acids in tea samples. 16 free amino acids in longjing, black, oolong, and pu-erh teas were separated and collected after FMOC-Cl derivatization in the first dimension, and the fractions were collected and concentrated and then separated on a chiral column.
