The detection method of methyl hesperidin mainly adopts high-performance liquid chromatography (HPLC). The following is a typical detection condition and steps:

Detection conditions
Chromatographic column: Shim-pack VP-ODS or other suitable chromatographic columns are used.
Mobile phase: acetonitrile-0.025 mol/L potassium dihydrogen phosphate (5 mL triethylamine is added to every 1 L, and the pH is adjusted to 3.0 with phosphoric acid) (25:75) as the mobile phase, and the flow rate is 1.0 mL/min.
Column temperature: set to 30℃.
Detection wavelength: usually detected at two wavelengths of 261 nm and 283 nm.
Detection steps
Sample preparation: Take an appropriate amount of methyl hesperidin sample, dissolve, and dilute to a certain concentration with an appropriate solvent (such as methanol, ethanol, etc.) as the test solution.
Preparation of reference substance: Take a methyl hesperidin reference substance of known concentration, dissolve and dilute it to a certain concentration with an appropriate solvent, and use it as the reference solution.
Injection: Inject the test solution and the reference solution into the high-performance liquid chromatograph for separation and detection.
Data recording and processing: record the chromatogram and calculate the content of methyl hesperidin in the sample based on the peak area or peak height. By comparing with the reference solution, the purity and content of methyl hesperidin in the sample can be determined.
In addition, other methods can be used to detect methyl hesperidin, such as liquid phase mass spectrometry (Mass), nuclear magnetic resonance (NMR), etc., which can provide richer structural information and more accurate quantitative results. However, it should be noted that different detection methods may have different sensitivities and specificities. Therefore, in practical applications, the appropriate method should be selected for determination according to specific needs and experimental conditions.

Precautions
Sample processing: Contamination and loss should be avoided during sample processing to ensure the accuracy and representativeness of the sample.
Instrument calibration: Before using the high-performance liquid chromatograph, instrument calibration, and performance verification should be performed to ensure the accuracy and reliability of the test results.
Data storage and processing: The test data should be properly stored, and appropriate processing and analysis should be performed to draw accurate conclusions.
In summary, the detection method of methyl hesperidin mainly uses high-performance liquid chromatography, and it can also be combined with other methods for comprehensive analysis. During the testing process, attention should be paid to issues such as sample handling, instrument calibration, and data storage and processing to ensure the accuracy and reliability of the test results.
