Manufacturing Quality Control of L-Ornithine L-aspartate salt
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Assay (Main Component Analysis) | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a mobile phase consisting of phosphate buffer and organic solvents (e.g., methanol or acetonitrile). Detection is performed using a UV detector (typically 200–220 nm) to measure the peak areas of L-ornithine and L-aspartic acid. Quantification is carried out via external or internal standard methods to ensure the purity of the main component complies with pharmacopoeial requirements. |
| Purity Analysis | Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) | Combines liquid chromatography with tandem mass spectrometry to precisely identify molecular weight and structural characteristics, enabling confirmation of the target compound and detection of trace impurities (e.g., isomers, degradation products). This is a high-sensitivity and high-specificity method for purity assessment. |
| Amino Acid Composition Analysis | Amino Acid Analyzer (Ion-Exchange Chromatography or Post-derivatization HPLC) | After acid hydrolysis of the sample, amino acids are separated via ion-exchange chromatography or following derivatization (e.g., with DNP or PITC), then quantified using standard amino acid reference substances. This verifies whether the molar ratio of ornithine to aspartic acid conforms to the specified ratio (typically 1:1). |
| Impurity Detection (Related Substances) | HPLC (Main Component Self-Control Method) | HPLC is used to detect potential impurities (e.g., unreacted starting materials, by-products, oxidation products). Impurity limits are set (e.g., ≤0.5%) to monitor product stability and the reliability of the synthetic process. |
| Residual Solvent Detection | Gas Chromatography (GC) | Residual organic solvents (e.g., ethanol, acetone, dichloromethane) potentially present during synthesis are detected using headspace or solution injection methods. Risk assessment is performed in accordance with ICH Q3A/B guidelines to ensure compliance with safety limits. |
| Microbial Limit Test | Microbial Enumeration (Aerobic Bacteria, Mold/Yeast) | Uses culture-based methods to detect microbial contamination in the sample, applicable to non-sterile formulations, ensuring compliance with microbial limit standards specified in the Chinese Pharmacopoeia. |
| Heavy Metal Detection | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Following sample digestion, the content of heavy metals such as lead, cadmium, mercury, and arsenic is measured to ensure they remain below pharmacopoeial limits (e.g., lead ≤10 ppm), guaranteeing safety. |
| Appearance and Physical Properties | Visual Inspection + Physical Property Measurement | Visual assessment of powder color, morphology, and odor, along with measurement of physical parameters such as melting point, specific rotation, and pH, serve as preliminary quality indicators. |
| Water Content Determination | Karl Fischer Titration | Uses coulometric or volumetric Karl Fischer titration to precisely determine water content in the sample, preventing moisture absorption that could compromise stability or formulation performance. |
