Objective To establish a quality standard forZishen Tongguan Capsules.Methods Anemarrhneae Rhizoma and Phellodendri Chinensis Cortex were qualitatively identified by TLC method. The contents of neomangferin, phellodendrine hydrochloride, mangiferin and berberine hydrochloride inZishen Tongguan Capsules were quantitatively determined by HPLC method.Results The spots of qualitative identification method were clear without interference. Neomangferin in Anemarrhneae Rhizoma and phellodendrinehy drochloride in Phellodendri Chinensis Cortex were identified. Neomangferin, phellodendrinehy drochloride, mangiferin and berberine hydrochloride showed good linearity in the range of 0.025 25–2.02 μg (r=0.999 7), 0.025 5–2.04 μg (r=0.999 7), 0.026–2.08 μg (r=0.999 7), and 0.025 5–2.04 μg (r=0.999 6) respectively. The average recoveries of neomangferin, phellodendrinehy drochloride, mangiferin and berberine hydrochloride were 99.99%, 101.06%, 103.05%, and 100.55%, respectively. The RSD were 2.69%, 5.62%, 2.49%, and 2.06%, respectively.Conclusion The method is accurate and rapid, with good stability, reliability and reproducibility, which can be used for the quality control and evaluation of the preparation of Zishen Tongguan Capsules.

Objective To establish quality standards forAnshu Liquid.Methods Phellodendri Chinensis Cortex and Kochiae Fructus were qualitatively identified by TLC method. The contents of berberine hydrochloride and phellodendrine hydrochloride in the preparation were determined by HPLC method. The chromatographic column was ZORBAX SB-C18 (4.6 mm×250 mm, 5μm); the mobile phase was acetonitrile-0.1% phosphoric acid (0.5% diethylamine) gradient elution; the flow rate was 1.0 mL/min; the detection wavelength was 284 nm.Results Berberine hydrochloride and phellodendrine hydrochloride in Phellodendri Chinensis Cortex and saponin Ic in Kochiae Fructus were detected by TLC method. The linear relationship of berberine hydrochloride in the preparation was Y=23.109X?30.548,r2=0.999 8, RSD=2.97%, showing that the linear range of berberine hydrochloride was 0.050 5– 2.525 0 μg. The linear relationship of phellodendrine hydrochloride in the preparation wasY=10.038X?2.446 6, r2=0.999 9, RSD=1.24%, showing that the linear range of phellodendrine hydrochloride was 0.050 0–2.500 0 μg. Conclusion The method is accurate, rapid, stable and reliable, with good reproducibility, which can be used for the quality control and evaluation ofAnshu Liquid.
