Abstract:

Objective: To establish an high performance liquid chromatography fingerprint for quality control and evaluation
of ultra-micro powder of Astragali Radix. Methods: Chromatographic separation was achieved on an Inertsil ODS-SP
column (4.6 mm × 250 mm, 5 μm) with mobile phase A (methanol-acetonitrile, 1:1) and mobile phase B (ultra-pure water)
at a flow rate of 0.8 mL/min. In addition, the detection wavelength and column temperature were set at 260 nm and 25 ℃,
respectively. Results: Twelve peaks common to the established fingerprints were identified. Cluster analysis suggested apparent
geographic differences between the samples from the north and the south. Conclusion: The proposed method is simple,
accurate, repeatable and suitable for the quality control and evaluation of Astragali Radix ultra-micro powder.

Key words: ultra-micro powder of Astragali Radix, high performance liquid chromatography (HPLC), chromatographic fingerprint, similarity
