title: [Determination of rhein in plasma of rat by HPLC/MS].
abstract: A HPLC/MS method has been established for the determination of rhein in rat plasma, using an Alltima C18 column (4.6 x 250 mm, 5 microns) and a mixture of ACN-water (60:40) as the mobile phase, at the flow rate of 0.8 ml/min with the column temperature at 25 degrees C. The results showed that the level of rhein distributed in plasma reached the max value 0.5 h after the oral administration, and maintained a relatively high value from 0.25 h to 1.5 h. The method possessed high selectivity and sensitivity.
