Manufacturing Quality Control of Aloin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Aloin Content) | HPLC-UV | Quantifies aloin isomers using reversed-phase chromatography with UV detection at 270 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-DAD | Separates and detects structurally related impurities (e.g., aloe-emodin, barbaloin isomers) using diode-array detection for spectral confirmation. |
| Loss on Drying | Gravimetric (105 C drying) | Measures volatile content by weight loss after drying at 105 C to constant mass under controlled conditions. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Determines inorganic residue by incineration of sample at 600-800 C followed by weighing of sulfate-stabilized ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Simultaneously quantifies trace heavy metals via plasma ionization and mass spectrometric detection with isotopic resolution. |
| Arsenic | Hydride Generation-AAS | Converts arsenic to arsine gas, which is atomized and measured by atomic absorption at 193.7 nm. |
| Lead | Graphite Furnace-AAS | Atomizes lead in graphite furnace and measures absorption at 283.3 nm for high-sensitivity quantification. |
| Microbial Enumeration (Total Aerobic Count) | Plate Count Agar (ISO 4833-1) | Viable aerobic bacteria are cultured on nutrient agar and enumerated by colony formation after incubation at 30 C for 72 h. |
| Yeast and Mold Count | Sabouraud Dextrose Agar (ISO 21527-1) | Fungal colonies are grown on selective medium and counted following incubation at 25 C for 5 days. |
| Residual Solvents (Ethanol, Acetone, Ethyl Acetate) | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection against certified standards. |
| pH (1% w/v aqueous suspension) | Potentiometric (pH meter) | Measures hydrogen ion activity in a standardized suspension using calibrated glass electrode system. |
| Specific Optical Rotation | [alpha]D (Polarimetry) | Determines chiral purity by measuring the angle of rotation of plane-polarized light at 589 nm using sodium D-line source. |
