Objective: To survey the quality standards of Ginseng Radix et Rhizoma Rubra slices. Method: This experiment was carried out to observe the characters

identify the quality by microscopy and TLC

and make the content determination by HPLC for the Ginseng Radix et Rhizoma Rubra slices from different areas. The chromatographic column was Lichrospher C18(4.6 mm×150 mm

5 μm) with gradient elution of acetonitrile and water. The detection wavelength was set at 203 nm;the flow rate was at 1.0 mL·min-1and the column temperature was set at 30 ℃ respectively. Result: The appearances of samples were different when micro-characteristic was obvious and TLC spots were clear on the corresponding position of ginseng control medicine

ginsenoside Rf

Rg1

Re and Rb1.Concentration range of Rg1+Re was 0.097 0%-0.301% when concentration range of Rb1 was 0.140%-0.310% in thirteen batches of samples. Conclusion: The content of ginsenoside Rg1

Re and Rb1 was considerably different as well as the characters and micro-characteristics of slices.The study provides a reference for standards of Ginseng Radix et Rhizoma Rubra slices which need to be formulated.
