OBJECTIVE: To establish the quality standard for Shenfu yishen capsule. METHODS: The microscopic characteristics of Gymnadenia conopsea were detected; TLC was adopted for the qualitative identification of Salvia miltiorrhiza, Rheum palmatum, Glycyrrhiza uralensis, Rhodiola rosea and Cortex cinnamomi; HPLC was used for the content determination of astragaloside: the column was Phenomenex Luna-C18 with mobile phase of acetonitrile-water (35 ∶ 65,V/V) at a flow rate of 1.0 ml/min, column temerpature was 30 ℃. RESULTS: Microscopic identification features of G. conopsea were exclusive, TLC identification of S. miltiorrhiza, R. palmatum, G. uralensis,R. rosea and C. cinnamomi was well separated and specific; the linear range of astragaloside was 0.832 8-4.164 0 μg (r=0.999 9);RSDs of precision, stability and reproducibility tests were no higher than 2.03%;recovery was 95.02%-104.33%(RSD=3.80%,n=6). CONCLUSIONS: The standard can effectively control the quality of Shenfu yishen capsule.
