Notopterygium detection

The detection methods of Notopterygium include the following aspects:

1. Identification detection
Microscopic identification method
Use a microscope to observe the tissue structure of Notopterygium, and identify its authenticity through its cell morphology, arrangement, and other characteristics.
Thin layer chromatography (TLC)
The chemical components in Notopterygium are detected by TLC and compared with the standard spectrum to confirm its type and purity.
2. Content Determination
High-performance liquid chromatography (HPLC)
Accurately determine the content of active ingredients in Notopterygium, such as Notopterygium lactone I, Notopterygium lactone II, Notopterygium alcohol, and iso imperatorin. This method has high sensitivity and accuracy and is a common method for Notopterygium content determination.
3. Physical property detection
Water content detection
Use moisture determination techniques such as the Karl Fischer method to detect the moisture content in the sample to ensure that Notopterygium meets the storage and use requirements.
Ash detection
Determine the total ash and acid-insoluble ash in Notopterygium to evaluate the purity of the sample.
4. Safety Testing
Heavy Metal Testing
Use atomic absorption spectrometry (AAS) and other measurement techniques to detect whether Notopterygium contains excessive heavy metals, such as lead, mercury, cadmium, etc.
Pesticide Residue Testing
Use gas chromatography-mass spectrometry (GC-MS) and other methods to evaluate whether Notopterygium contains residual pesticide components.
Sulfur Dioxide Residue Testing
Use ion chromatography and other methods to detect whether sulfur dioxide preservatives are added to Notopterygium during processing.
Microbial Limit Testing
Use microbial incubators and corresponding culture and counting methods to detect whether Notopterygium contains excessive bacteria, molds, and other microorganisms.
