According to the production process of Ganmaoling Tablets, the active ingredients of traditional Chinese medicines are extracted by hydrothermal solvent extraction and hot dipping. The solubility of acetylsalicylic acid and the main effective components of several traditional Chinese medicines in water and organic solvents are different, and chloroform is used to extract acetylsalinum. After acid, it was titrated with sodium hydroxide to determine its content. Determination method: Acetylsalicylic acid, the first pharmaceutical factory in Huainan City, Anhui Province, according to the Chinese Pharmacopoeia 77-year-determination method measured the content of 100.1%. 1. Selection and Recovery Test of Acetylsalicylic Acid Solvent in Extract Insam Lingling Tablet: Take Ganmaoling Granules (without acetylsalicylic acid)
