Objective To determine the contents of 5 anthraquinones (aloe-emodin, phein, emodin, chrysophanol, physcion)in Huangzhi Neiyi Capsule through a quantitative analysis of multi-component by single-marker(QAMS), To determine the application value of QAMS by comparing with external standard method (ESM). Methods HPLC was performed at 30 ℃ with Waters Symmetry C18 column (4.6 mm × 250 mm, 5 μm), methanol-0.4% phosphoric acid (8515) as mobile phase at the wavelength 440 nm, and flow rate of 1.000 mL/min. The relative correction factors of other anthraquinones were calculated respectively by emodin as the reference. Results The values calculated by QAMS were compared with the values measured by ESM, and no significant difference was showed (RSD<5%). Conclusion For the availability and reliability, QAMS can be applied for quality evaluation of Huangzhi Neiyi Capsules.
