Area of Science:

  • Agricultural Chemistry
  • Food Science
  • Toxicology

Background:

  • Astragalus (Huangqi) is a widely used traditional Chinese medicine.
  • Pesticide and mycotoxin contamination is a concern in herbal products.
  • Understanding contaminant transfer during processing is crucial for safety.

Purpose of the Study:

  • To investigate the fate of pesticides and mycotoxins during Astragalus processing.
  • To determine processing factors for various contaminants.
  • To assess potential health risks associated with residues.

Main Methods:

  • Systematic analysis of 13 pesticides and 9 mycotoxins in processed Astragalus.
  • Quantification of residues using chromatographic techniques.
  • Calculation of processing factors for different steps (water extraction, alcohol precipitation, drying).

Main Results:

  • Phosphamidon, fenamiphos-sulfoxide, deoxynivalenol, and T-2 toxin were frequently detected.
  • Drying significantly increased pesticide residues, with processing factors up to 22.41 for phorate-sulfoxide.
  • Pesticide transfer correlated with physicochemical properties like melting point and vapor pressure.

Conclusions:

  • Astragalus processing, particularly drying, can concentrate pesticide residues.
  • Certain pesticides (demeton, fenamiphos-sulfoxide) may pose chronic risks post-drying.
  • Data supports developing strategies for controlling residues to ensure Astragalus product safety.
