| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column, with a mobile phase of methanol-water or acetonitrile-water for gradient or isocratic elution, and a UV detector (typically at 283 nm) to detect the peak area of naringin. The content is calculated using an external standard method or internal standard method. This method has strong specificity and good repeatability, and is a commonly used method in pharmacopoeias. |
| Content Determination | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilizes the characteristic absorption of naringin at a specific wavelength (e.g., 283 nm) to determine its concentration in the sample by the standard curve method. It is simple to operate and low-cost, but is susceptible to interference from coexisting components, making it suitable for preliminary quantification or screening. |
| Identification Test | Thin Layer Chromatography (TLC) | Sample and reference substance are spotted on a silica gel G TLC plate, developed with an appropriate developing solvent (e.g., ethyl acetate-methanol-water), and then visualized (using reagents such as aluminum chloride or vanillin-sulfuric acid). Fluorescent or colored spots are observed under UV light, and identification is performed by comparing Rf values and colors. |
| Identification/Purity Analysis | High-Performance Liquid Chromatography-Mass Spectrometry Coupling (HPLC-MS) | Combines the separation capability of HPLC with the structural identification function of mass spectrometry. The presence of naringin can be confirmed by the molecular ion peak ([M−H]⁻ m/z 609) and fragment ions, and impurities or degradation products can also be detected. It is suitable for accurate qualitative and semi-quantitative analysis in complex matrices. |
| Purity/Impurity Check | High-Performance Liquid Chromatography (HPLC) | Under the conditions of content determination, the purity of the sample is checked by normalization of the main peak area or setting an impurity limit, to detect other flavonoid impurities or degradation products (such as naringenin), and to evaluate whether the purity of naringin meets the quality standards. |
| Solubility/Physical Properties | Appearance and Solubility Test | According to specifications such as the Chinese Pharmacopoeia, naringin is observed to be a white or off-white crystalline powder, slightly soluble in cold water, and easily soluble in methanol, ethanol, and alkaline aqueous solutions, serving as one of the primary indicators for initial quality control. |
