[Determination of amino acids in fu fang banlangen granulae by a pre-column derivatization RP-HPLC method].


OBJECTIVE To establish a pre-column derivatization reversed-phase high-performance liquid chromatographic method for the determination of amino acids, which was known as the characteristic constituents of Fu Fang Banlangen Granulae. METHODS We determined the amino acids in alkalescence by a pre-column derivatization of DNFB. NaAc buffer (pH 6.4… (More)
