摘要:... Oxidized species of homocysteine are converted to reduced form by sodium borohydride, and, after precolumn derivatization with 2-chloro-1-methylquinolinium tetrafluoroborate, homocysteine 2- S -quinolinium derivative is separated from those of other plasma thiol derivatives, and quantitated by ion-paired reversed-phase high-performance liquid chromatography with ultraviolet detection...
