Enzyme-linked Immunosorbent Assay in Quality Control of Chinese Medicines： A Review / 中国实验方剂学杂志

ABSTRACT

In the quality control of Chinese medicine， the detection of active components and toxic and harmful components are two important links. Although conventional methods such as high performance liquid chromatography and liquid chromatography-mass spectrometry can accurately quantify the above substances， they have shortcomings such as complicated operation， high costs， inability of detection at any time， difficult detection of insoluble and macromolecular substances. Enzyme-linked immunosorbent assay （ELISA） can adsorb antigens or antibodies on the surface of solid carriers and realize qualitative or quantitative analysis of targets by using the specific reactions of antigens and antibodies. This method is praised for the simple operation， high sensitivity， strong specificity， simple requirements for experimental equipment， a wide application range， and low costs. In recent years， ELISA has been widely used in the quality control of Chinese medicine， especially in the content determination of mycotoxins represented by aflatoxin and the qualitative and quantitative analysis of active components. ELISA plays an increasingly important role with its unique advantages， providing new methods and ideas for the rapid quality examination of large quantities of Chinese medicines. This paper reviews the research progress in ELISA for the quality control of Chinese medicine in recent years and prospects its technical development and application prospects， aiming to provide reference and research ideas for further using this method to ensure the quality， safety， and controllability of Chinese medicine.
