Determination of astragaloside in serum with anisic acid by spectrophotofluorimetry / 北京大学学报(医学版)

ABSTRACT

Objective: To develop a new determination method of astrogaloside in s erum by spectrophotofluorimetry. Methods: The fluorescence char acteristics of astragaloside anisic reaction product were used to determine astragaloside in serum. Re sults The reaction product of astrogaloside and anisic acid had excitatio n and emission maxima were at 320 and 387 nm, respectively. The linear range of determ inati on was between 0.2 and 40.0 mg*L －1. The detection limit was 0.02 mg*L －1.　The recovery of measurement was between 98.8% and 102.4%. Conclusion: The propos ed method has advantages of high sensitivity, low detection limit and no interference. It has been used to determine astragaloside in serum successfully.
