Abstract: Objective To establish quality control of Xinnaoling granules. Methods Thin layer chromatography (TLC) methods were used to identify Rhizoma Corydalis, Radix Angelicae dahuricae, Cortex Magnoliae officinalis, Radix Glycyrrhizae, Rhizoma Ligusticum, Ligusticum wallichii, Schisandra Chinensis, Dendranthema morifolium. The concentration of salvianolic acid B was determined by high performance liquid chromatography (HPLC). The method employed a column of Agilent Eclipse XDB-C18 (4.6 mm×250 mm,5 μm) with a mobile phase of 0.5% formic acid (A)-acetonitrile (B) at a temperature 25℃. The gradient elution program was as follow:0~5 min 24% B, 5~6 min 24%~19% B, 6~25 min 19~20% B. The flow rate was 1.0 ml/min, and the injection volume was 10 μl and the detection wavelength was 286 nm. Results The spots in TLC plates were clear and specific. As for salvianolic acid B, the linear range was 20-1280 μg/ml and the equation of linear regression of salvianolic acid B was Y=13.304 X-117.50 (r=0.9999, n=7). The average recovery rate was 96.17% (RSD=1.10%). Conclusion The method was proved to be simple, reliable, reproducible, and could be used in the quality control of Xinnaoling granules.
