Manufacturing Quality Control of Naringin
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | A reversed-phase C18 column is used with a mobile phase such as methanol-water-glacial acetic acid, applying gradient or isocratic elution. Detection is performed at 280–290 nm using a UV detector. Quantification of naringin is achieved by comparing retention time and peak area with reference standards. This method offers high sensitivity and good reproducibility, and is the most widely used method in pharmacopoeias and research. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Naringin exhibits characteristic absorption peaks near 283 nm and 288 nm. Identification is carried out by comparing the sample's absorption spectrum at specific wavelengths with that of a reference standard, serving as a preliminary identification tool. |
| Identification | Thin-Layer Chromatography (TLC) | Silica gel G plates are used with developing solvents such as ethyl acetate-methanol-water (e.g., 8:1:1). After development, spots are visualized using reagents like vanillin-sulfuric acid under heating. Identification is based on spot color and Rf values compared with reference substances. This method is simple and suitable for rapid screening. |
| Assay | Ultraviolet Spectrophotometry (UV) | This method measures absorbance at the maximum wavelength of naringin (approximately 284 nm) and determines concentration via a calibration curve. It is suitable for rapid determination of total flavonoids or naringin-like components in crude extracts, though it has lower specificity and is prone to interference. |
| Assay | Ultra-Performance Liquid Chromatography (UPLC) | Similar in principle to HPLC, but employs smaller particle-size packing materials and a high-pressure system, resulting in higher separation efficiency, shorter analysis time, and improved sensitivity. Ideal for accurate determination of naringin in high-throughput analyses or complex matrices. |
| Residual Solvents | Gas Chromatography (GC) | If organic solvents (e.g., methanol, ethanol) are used during naringin extraction, residual solvents can be analyzed by gas chromatography using a capillary column and FID detector, with limits controlled according to pharmacopoeial requirements. |
| Purity Test | HPLC-DAD or LC-MS | Combining high-performance liquid chromatography with diode array detection (DAD) or mass spectrometry (MS), this method assesses peak purity of naringin, identifies co-eluting impurities, and evaluates sample purity. Particularly useful for quality control of high-purity raw materials. |
| Simultaneous Multi-Component Analysis | UPLC-QTOF-MS / LC-MS/MS | Used for simultaneous qualitative and quantitative analysis of naringin and other flavonoid components in complex samples (e.g., herbal extracts). Offers high resolution and sensitivity, making it suitable for comprehensive quality evaluation and metabolic studies. |
