- 論文の詳細を見る
Capillary electrophoresis was applied to the estimation of synephrine levels in Evodia fruit and Chinese medicinal prescriptions that contain this crude drug. An AccuSep capillary column (75 μm i.d.×60cm) was used with a solvent of 40mM sodium dihydrogenphosphate - acetonitrile (9:1, adjusted to pH4.5 with phosphoric acid) as the electrophoretic buffer, and 12.5kV as the electrophoretic voltage, to obtain synephrine from Evodia fruit within about 20min. The same analytical conditions were applicable to the separation of synephrine from decoctions of 8 Chinese medicinal prescriptions. The use of 4-dimethylaminopyridine as an internal standard allows the level of synephrine in these drugs to be estimated accurately.
