Industrial Applications of Pterostilbene
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical & Healthcare | Antioxidant; intermediate for anti-inflammatory drugs | Extracted from plants or synthesized chemically for development of candidate drugs targeting cardiovascular diseases and cancer |
| Cosmetics | Anti-aging active ingredient | Extracted from Pterocarpus spp. via supercritical fluid extraction or solvent extraction, and incorporated into skincare formulations to exert antioxidant effects |
| Food Additives | Natural antioxidant | Produced via organic solvent extraction for extending food shelf life and inhibiting lipid oxidation |
| Biotechnology | Natural product for research | Manufactured using cell culture or plant tissue culture techniques for bioactivity studies and drug screening |
Manufacturing Quality Control of Pterostilbene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Pterostilbene Content) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 306 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection; impurities quantified relative to main peak using response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, As, Hg, Ni) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppq sensitivity. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum; reflects volatile content including water and residual solvents. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine total water content based on stoichiometric reaction with water. |
| Residue on Ignition | Sulfated Ash Test | Mass of inorganic residue remaining after high-temperature incineration in presence of sulfuric acid; indicates inorganic impurities. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral purity and identity of the enantiomerically pure compound. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, used for identity and purity assessment. |
| pH of Solution (1% w/v) | pH Meter | Measurement of aqueous suspension pH to detect acidic/basic degradation products or residual catalysts. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values for process consistency. |
| Microbial Contamination | Membrane Filtration | Quantitative enumeration of aerobic bacteria, yeast, and molds via filtration, membrane transfer to selective media, and colony counting. |
