Manufacturing Quality Control of D-(-)-Arabinose
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Scan the sample and reference standard in the range of 4000–400 cm⁻¹, compare characteristic absorption peaks to confirm molecular structural consistency. |
| Thin Layer Chromatography (TLC) | Use silica gel plates and an appropriate developing solvent system (e.g., n-butanol: acetic acid: water = 4:1:1), develop, visualize, and compare Rf values with those of reference standards. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a differential refractive index detector or evaporative light scattering detector; separate D-arabinose using amino or ion-exchange columns, and quantify by external standard method. |
| Polarimetry | Determine the optical rotation of the solution under sodium light (589 nm), calculate purity based on specific rotation formula, ensuring it falls within the pharmacopoeial range (+103° to +107°). | |
| Impurity Testing | Gas Chromatography (GC) | After derivatization (e.g., formation of trimethylsilyl ethers), detect residual organic solvents or volatile impurities. |
| HPLC (Related Substances) | Use gradient elution to detect other monosaccharides or degradation products in D-arabinose; calculate impurity peak area percentage. | |
| Drying Loss | Gravimetric Drying Method (Thermogravimetric Analysis) | Dry at 105°C until constant weight; calculate loss on drying to control moisture content (typically ≤1.0%). |
| Residue on Ignition | Sulfate Ash Method | Char the sample, treat with sulfuric acid, then ignite at high temperature (approximately 600–800°C), weigh the residue to assess inorganic impurity levels. |
| Solution Clarity | Visual Turbidity Comparison | Dissolve the sample to a specified concentration (e.g., 10%), visually compare with standard turbidity solutions to determine clarity. |
| Solution Color | Color Comparison Method | Compare the sample solution with standard color solutions (e.g., platinum-cobalt standard), ensuring it does not exceed the specified color limit. |
| Microbial Limits | Microbial Counting Method | Perform tests according to pharmacopoeia requirements for total aerobic bacteria count, mold and yeast count, as well as control organism testing (e.g., Escherichia coli). |
