| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Determination of Daidzein Content | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water for gradient or isocratic elution. Detection is performed using a UV detector at approximately 254 nm, with qualitative identification based on retention time and quantitative analysis via peak area. This method offers high sensitivity and excellent reproducibility, making it the most commonly used approach in pharmacopoeias and research. |
| Purity Analysis of Daidzein | Ultra-Performance Liquid Chromatography (UPLC) | Similar to HPLC, but employs smaller particle-sized stationary phases and high-pressure systems, resulting in higher separation efficiency and shorter analysis times, making it suitable for high-throughput and high-precision quality control. |
| Qualitative Identification of Daidzein | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilizes the characteristic absorption peaks of daidzein near 248 nm and 295 nm for preliminary identification. Often used for screening crude extracts, but has low specificity and should be confirmed with additional methods. |
| Structural Confirmation of Daidzein | Mass Spectrometry (MS) or LC-MS/MS | Combines liquid chromatography with mass spectrometry to confirm structure through molecular ion peaks ([M-H]⁻ m/z ≈ 253) and fragment ions. Particularly suitable for identifying target compounds in complex matrices. |
| Residual Solvent Testing | Gas Chromatography (GC) | Used to detect residual organic solvents (e.g., methanol, ethanol, benzene derivatives) that may remain during extraction, ensuring product safety and compliance with GMP and pharmacopoeial requirements. |
| Water Content | Karl Fischer Titration | Accurately measures water content in samples to prevent instability and degradation during storage due to excessive moisture. |
| Heavy Metals and Harmful Elements | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects levels of heavy metals such as lead, cadmium, arsenic, mercury, and copper to ensure compliance with food safety or pharmaceutical standards. |
| Microbial Limits | Microbial Culture Method | Performs testing for total bacterial, mold, and yeast counts, as well as specified control organisms (e.g., Escherichia coli, Salmonella spp.), according to pharmacopoeial requirements to ensure microbial safety. |
