Manufacturing Quality Control of Dehydroandrographolide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies dehydrated andrographolide by UV absorption at 225 nm using a reversed-phase C18 column and external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., andrographolide, neoandrographolide) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) using flame ionization detection with headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration based on the stoichiometric reaction of iodine with water. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (Pb, Cd, As, Hg) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue after high-temperature ashing (700-800 C) and subsequent weighing. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using sodium D-line light to confirm chiral integrity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dry powder form using Mie scattering theory. |
| Microbial Enumeration | Membrane Filtration | Quantifies aerobic mesophilic bacteria and fungi via filtration, membrane transfer, and colony counting on selective media. |
| Endotoxin Level | Kinetic Chromogenic LAL Assay | Detects bacterial endotoxins by measuring color development from Limulus amebocyte lysate enzymatic cascade. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
