[Determination of synephrine in oriental pharmaceutical decoctions containing Aurantii nobilis pericarpium by ion-pair high-performance liquid chromatography].
A simple method using ion-pair high-performance liquid chromatography was established for the rapid and precise determination of synephrine in oriental pharmaceutical decoctions containing Aurantii Nobilis Pericarpium. An ODS column and a mixture of water, acetonitrile, sodium dodecyl sulfate and phosphoric acid (65:35:0.5:0.1) as a mobile phase were used for the separation. Synephrine was eluted without interference by other co-existing components within 15 min.
