title: [Determination of sennoside A in oriental pharmaceutical decoctions containing Rhei Rhizoma by ion-pair high-performance liquid chromatography].
abstract: A simple method using ion-pair high-performance liquid chromatography was established for the rapid and precise determination of sennoside A in oriental pharmaceutical decoctions containing Rhei Rhizoma. This method was compared with other two methods, i.e. ion-suppression and phosphate buffer methods. Sennoside A was eluted without interference in this ion-pair method, while the determination of sennoside A was interfered by co-existing components in the other two methods.
