Article Synopsis
  • Baishouwu is a traditional Chinese medicine derived from three species, CA, CB, and CW, which have different flavors and chemical compositions, highlighting the need for accurate differentiation among them.
  • The researchers used a combination of E-tongue, E-nose, and UPLC-Q-TOF/MS to analyze 15 batches of Baishouwu samples, looking for flavor differences and key metabolites.
  • The findings revealed distinct flavor profiles for each species and identified eight critical differential metabolites, which could help establish quality standards and enhance the application of Baishouwu in traditional medicine.

In this study, a powerful and rapid aqueous two-phase system (ATPS) method was used to extract polysaccharides from Codonopsis pilosula. The ATPS process was investigated with response surface methodology (RSM). At an ammonium sulfate concentration of 17%, ethanol concentration of 30%, and extraction temperature of 40 °C at pH 6, the total extraction yield of polysaccharides reached (31.
