HPLC fingerprints of Radix astragali of different sources

Haiyan Mai

Abstract

AIM: To make comparative study on HPLC fingerprints of several kinds of Radix astragali from different sources. METHODS: ODS column was used,with mixture of acetonitrile and water as mobile phase in a gradient mode.The flow rate was 1.0 mL·min~(-1).The wavelength of measurement was at 203 nm. RESULTS: The fingerprints of Radix astragali were obtained. CONCLUSION: This method can be used to identify Radix astragali from different sources conveniently.
