Deternination of catecholamines in plasma by high performance liquidchromatography coupled with fluorescence detection[J]. Journal of Chongqing Medical University, 1997,(3).DOI:
A senaitive fluorimetric method for the determination of catecholamines in human plasma was described. After liquid - liquid extraction with diphenylboric acid 2 - aminoethyl ester
the catecholamines in plasma are converted into the corresponding fluorescent compounds by reaction with 1
2 - diphenylethylenediamine in aqueous acetonitrile. After being isocraticly eluted by a methanol buffer solution
these compounds could completely be separated with 16 minutes on Shim - pack CLC - ODS column
and with 10 minutes on Waters Nova - pack C18 column
The limits of detection were 10 fmol for norepinephrine
10 fmol for epinephrine and 12.5 fmol for dopamine reapectively.
