Manufacturing Quality Control of L-(+)-Ergothioneine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies ergothioneine concentration using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities (e.g., hercynine, oxidation products) via gradient HPLC-UV against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection and external calibration. |
| Heavy Metals | ICP-MS | Determines total content of toxic elements (Pb, Cd, As, Hg, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Water Content | Karl Fischer Titration | Measures total water content volumetrically or coulometrically using iodine-based redox titration in anhydrous methanol medium. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| pH (1% aqueous solution) | pH Meter | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode in deionized water at 25 C. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content by ignition at 700-750 C followed by weighing of residual non-volatile matter. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (E. coli, Salmonella, S. aureus) using membrane filtration and selective agar culture. |
| Particle Size Distribution | Laser Diffraction | Measures dry powder particle size distribution (D10, D50, D90) using laser light scattering principles under controlled dispersion conditions. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content (excluding water) by measuring weight loss upon heating at 105 C for 2 hours under forced-air conditions. |
| Identity Confirmation | FTIR Spectroscopy | Verifies molecular structure by comparing sample infrared absorption spectrum (4000–400 cm-1) to reference standard spectrum using KBr pellet method. |
