Area of Science:

  • Herbal Medicine
  • Pharmacognosy
  • Analytical Chemistry

Background:

  • Radix Astragali (RA) quality is traditionally assessed by sweetness.
  • Scientific validation of sweetness as a reliable indicator for RA quality is lacking.
  • Components contributing to RA sweetness require thorough analysis.

Purpose of the Study:

  • To identify sweetness components in Radix Astragali.
  • To develop and validate a sweetness-based quality evaluation method for RA.
  • To investigate the correlation between sweetness and established RA quality indicators.

Main Methods:

  • Identification of seven sweetness components in RA.
  • Development of a quality evaluation method based on identified sweetness components.
  • Characterization of 48 RA samples using the new method and a comprehensive index based on astragaloside IV, calycosin glucoside, polysaccharides, and extracts.

Main Results:

  • Seven sweetness components were identified in Radix Astragali.
  • A novel sweetness-based quality evaluation method for RA was established.
  • A strong positive correlation was observed between the level of sweetness and a comprehensive quality index for RA.

Conclusions:

  • Sweetness is a significant quality attribute of Radix Astragali.
  • The study provides scientific evidence supporting the use of sweetness as a reliable indicator for RA quality assessment.
  • This research validates traditional practices with modern scientific methodology.
