Manufacturing Quality Control of Curdione
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies莪术二酮 by separation on a reversed-phase column and UV detection at ~254 nm, comparing peak area to a reference standard calibration curve. |
| Related Substances | HPLC-DAD or HPLC-MS | Detects and semi-quantifies structurally related impurities (e.g., curdione, furanodiene) using diode-array detection or mass spectrometric identification with relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies residual solvents (e.g., methanol, ethyl acetate, dichloromethane) using capillary GC with flame ionization detection against certified standards. |
| Heavy Metals | ICP-MS | Determines trace levels of toxic elements (Pb, Cd, As, Hg, Cr) via inductively coupled plasma mass spectrometry after acid digestion and matrix-matched calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Measures water content electrochemically by iodine generation and stoichiometric reaction with water in anhydrous methanol-based electrolyte. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content by high-temperature incineration (500–600 °C) followed by precise weighing of the non-volatile residue. |
| Optical Rotation | [α]D Measurement | Determines specific optical rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric consistency. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid transition using calibrated capillary apparatus per pharmacopoeial standards (e.g., USP <741>). |
