Objective:To establish the quality standard of soil stir-baked angelica,sesame oil stir-fried angelica and carbonized angelica.Methods:With reference to the technical requirements under angelica sinensis in the Pharmacopoeia of the People's Republic of China,2020 edition,the traits of ten batches of soil stir-baked angelica,eight batches of sesame oil stir-fried angelica,and eleven batches of carbonized angelica produced in Gansu were compared to describe the trait characteristics of these angelica.Powder microscopic identification and TLC(thin layer chromatography)identification of three kinds of angelica were established to determine the contents of water,total ash,acid-insoluble ash,alcohol-soluble extractives and ferulic acid.Results:The traits of these angelica were basically the same,in the form of rounded,orbicular or irregularly striped flakes,but each has different colors and subtle features;both soil stir-baked angelica and sesame oil stir-fried angelica showed the microscopic characteristics of angelica control powder;soil stir-baked angelica,sesame oil stir-fried angelica and carbonized angelica had TLC of angelica control herb,ferulic acid and ligustilide were detected from soil stir-baked angelica and sesame oil stir-fried angelica.Average content of ferulic acid from ten batches of soil stir-baked angelica was 0.067%,average content of ferulic acid from eight batches of sesame oil stir-fried angelica was 0.062% .Conclusion:The measurements in the study could provide the reference for the establishment of local standard of processed Danggui.
