A Preliminary Investigation into the Effects of Sulfur Fumigation on the Quality of Baizhu(Atractylodis Macrocephalae Rhizoma)
Objective A preliminary study was conducted on the quality assessment of Baizhu(Atractylodis Macrocephalae Rhizoma)herbal materials before and after sulfur fumigation,and a method for quality evaluation before and after sulfur fumigation was established.Methods Based on market research,samples of Baizhu(Atractylodis Macrocephalae Rhizoma)subjected to sulfur fumigation at varying degrees were prepared.By embracing an integrated approach of internal and external comparative principles,the colorimetric values,residual sulfur dioxide,and sulfite levels of Baizhu(Atractylodis Macrocephalae Rhizoma)before and after sulfur fumigation were measured.The material basis changes of Baizhu(Atractylodis Macrocephalae Rhizoma)pre-and post-sulfur fumigation were characterized using liquid chromatographic fingerprinting.Additionally,ATR-FTIR spectroscopy coupled with pattern recognition technology was employed to compare differences in mid-infrared spectral absorption.Results This experiment prepared Baizhu(Atractylodis Macrocephalae Rhizoma)medicinal materials without sulfur fumigation and with low,medium,and high concentrations of sulfur fumigation.The experimental results showed that as the degree of sulfur fumigation increased,the brightness increased,the total color value increases,the residual sulfur dioxide and sulfite increased,and the content of alcohol-soluble extracts and main components decreased.The ATR-FTIR spectrum showed a significant stretching vibration absorption peak of sulfite ions,while the-OH absorption peak gradually decreased.Combining the PCA and OPLS-DA analysis can effectively distinguish sulfur-fumigated and non-sulfur-fumigated samples.Conclusion Sulfur fumigation seriously affects the quality of Baizhu(Atractylodis Macrocephalae Rhizoma)medicinal materials.This study comprehensively and objectively evaluates the impact of sulfur fumigation on the quality of Baizhu(Atractylodis Macrocephalae Rhizoma),which can provide a reference for the origin processing and quality assessment of Baizhu(Atractylodis Macrocephalae Rhizoma)medicinal materials.
