The simultaneous separation and determination of major anthraquinones (emodin, chrysophanol, rhein and their glucosides, aloe-emodin, sennoside A, and sennoside B) of Rhei Rhizoma were achieved by cyclodextrin modified capillary zone electrophoresis. The running electrolyte used in this method was 0.005 M alpha-cyclodextrin in 0.03 M borate buffer (pH 10.0) containing 20% acetonitrile, with an applied voltage of 20 kV.
采用环糊精修饰的毛细管区带电泳法，实现了大黄根茎中主要蒽醌类成分（大黄素、大黄酚、大黄酸及其糖苷、芦荟大黄素、番泻苷A和番泻苷B）的同时分离与测定。该方法所用的运行电解质为含20%乙腈的0.03 M硼酸盐缓冲液（pH 10.0）中0.005 M的α-环糊精，施加电压为20 kV。
