ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of different chromatographic conditions on QAMS relative correlation factors (RCF) and relative retention values (RT(R)).</p><p><b>METHOD</b>C18 columns were used with methyl alcohol-0.4% phosphoric acid water (85 15) as the mobile phase. The detection wavelength was 254 nm, the column temperature was 30 degrees C, and the flow rate was 1.0 mL x min(-1). The five anthraquinones in Rhei Radix et Rhizoma were selected to be the objects of study. The RCF and RT(R) among aloe-emodin, rhein, chrysophanol, physcion and emodin were determined under different chromatographic conditions.</p><p><b>RESULT</b>Their RCFs showed no significant difference.</p><p><b>CONCLUSION</b>The RCFs among anthraquinones established by QAMS can be used as a constant in content determination of traditional Chinese medicines/patent traditional Chinese medicines.</p>
