Industrial Applications of Dihydromyricetin
| Industry | Application | Process |
|---|---|---|
| Food Industry | Natural antioxidant; food preservative | Added to beverages, alcoholic drinks, baked goods, and meat products to retard oxidative spoilage by scavenging free radicals |
| Pharmaceutical Industry | Active pharmaceutical ingredient for hepatoprotective drugs; anti-inflammatory and antioxidant agent | Used in oral formulations for treating alcoholic liver injury and non-alcoholic fatty liver disease; purified via aqueous extraction followed by ethanol precipitation and macroporous resin chromatography |
| Cosmetics Industry | Skin antioxidant; anti-photoaging agent | Formulated into serums, moisturizers, and other skincare products to exert protective effects by inhibiting UV-induced ROS generation; commonly stabilized using microencapsulation or liposomal encapsulation |
| Dietary Supplement Industry | Functional ingredient in dietary supplements | Utilized in liver-support and antioxidant supplement development; frequently combined with puerarin and silymarin, and processed into capsules or tablets via spray-drying granulation |
Manufacturing Quality Control of Dihydromyricetin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 290 nm. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities using gradient HPLC with diode array detection for spectral confirmation. |
| Loss on Drying | Gravimetric Method | Measurement of mass loss after drying under controlled temperature and vacuum to determine volatile content including residual solvents and moisture. |
| Residual Solvents | GC-FID | Identification and quantification of common organic solvents using gas chromatography with flame ionization detection and internal standard calibration. |
| Heavy Metals | ICP-OES | Multi-element determination of toxic metals (e.g., Pb, Cd, As, Hg) by inductively coupled plasma optical emission spectrometry after acid digestion. |
| Sulfated Ash | Gravimetric Method | Determination of inorganic residue after charring and sulfuric acid treatment followed by high-temperature incineration and weighing. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify water based on stoichiometric reaction with iodine and sulfur dioxide. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and identity of the enantiomerically pure compound. |
| pH of Solution | Potentiometric Method | Determination of pH in aqueous suspension (1% w/v) using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via light scattering pattern generated by dispersed particles in air. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic bacteria and detection of specified pathogens (e.g., E. coli, Salmonella) following USP <61> and <62>. |
| Organic Volatile Impurities | GC-MS | Screening and identification of unknown volatile impurities using gas chromatography coupled with mass spectrometry and library matching. |
