Manufacturing Quality Control of Tetrahydrocurcumin
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | An HPLC method using a reversed-phase C18 column, with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (e.g., 230–254 nm). The content of tetrahydrocurcumin is quantified by external or internal standard methods. This method offers high sensitivity, accuracy, and reproducibility, and is currently the most widely used quantitative analytical method. |
| Purity Analysis | High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) | A method combining the separation capability of HPLC with the qualitative identification ability of mass spectrometry. It can effectively identify tetrahydrocurcumin and its main impurities (e.g., incompletely reduced curcumin, oxidation products), enabling high-purity analysis and structural confirmation. |
| Impurity Detection | HPLC-DAD (Diode Array Detector) | Based on HPLC with the addition of a DAD detector, which allows acquisition of UV absorption spectra for each peak, enabling preliminary qualitative identification of impurities and helping to detect structurally similar impurities. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Using techniques such as ¹H-NMR and ¹³C-NMR to accurately identify the molecular structure of tetrahydrocurcumin, confirming its chemical structure and stereochemistry. NMR is considered the gold standard for structural confirmation and is suitable for use in the research phase or reference standard preparation. |
| UV-Visible Spectroscopy Analysis | UV-Vis Spectrophotometry | Determines the characteristic absorption peaks of tetrahydrocurcumin at specific wavelengths (e.g., 240–260 nm) for preliminary qualitative or auxiliary quantitative analysis. It is simple to operate but has relatively low specificity, often used as a supplementary method. |
| Specific Optical Rotation Determination | Polarimetry | Tetrahydrocurcumin is optically active; its optical purity can be assessed by measuring the specific optical rotation ([α]₂₀ᴰ), especially useful for quality control of chiral compounds. |
| Thermal Analysis (Melting Point / Thermogravimetric Analysis) | Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA) | Used to determine the melting point range and thermal stability of tetrahydrocurcumin, aiding in assessing its purity and identifying crystalline water or degradation products. |
