Abstract:
OBJECTIVETo establish a method for detecting the fingerprint of Radix Astragali by RRLC-UV-MS.
METHODSeparation was performed on an Agilent Zorbax Extend C18 column (2.1 mm x 100 mm, 1.8 microm). Gradient elution was performed by the mobile phases consisting of acetonitrile and 0.1% formic acid with the flow rate of 0.3 mL x min(-1), the detection wavelength was set at 254 nm, and the column temperature was 30 degrees C.
RESULTThe method of fingerprint analysis on Radix Astragali by RRLC-UV-MS was established. Eleven samples of Radix Astragali were analyzed, the similarities were over 0.92, and seven peaks in the fingerprint were designated.
CONCLUSIONThe method can be applied to the quality control and studies on chemical constituents of Radix Astragali.
