Industrial Applications of 2α,19α－Dihydroxyursolic acid
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Skin-lightening, anti-inflammatory, and antioxidant active ingredient | Incorporated into formulations such as emulsions, serums, and masks at typical concentrations of 0.01–0.5% w/w; used in conjunction with stabilizers (e.g., glycerin, butylene glycol) and pH adjusters (pH 5.0–6.5) to ensure chemical stability |
| Pharmaceutical R&D | Natural product lead compound for research on antitumor, antidiabetic, and hepatoprotective mechanisms | Administered via intraperitoneal injection or oral gavage (dose range: 5–50 mg/kg) in vitro cell models (e.g., HepG2, A549) and murine disease models; typically dissolved in DMSO and diluted with saline prior to use |
| Refinement of plant extracts | High-purity ursolic acid derivative reference standard or control substance | Enriched using macroporous adsorption resin (e.g., HPD-100), followed by purification via preparative high-performance liquid chromatography (C18 column, methanol–water gradient elution); purity ≥98% for quality control applications |
Manufacturing Quality Control of 2α,19α－Dihydroxyursolic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities using gradient HPLC with diode-array detection for spectral confirmation. |
| Residual Solvents | GC-FID | Identification and quantification of organic solvents (e.g., methanol, ethyl acetate) based on retention time and flame ionization response. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, As, Hg) after acid digestion, using mass spectrometry for ultra-trace sensitivity. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measurement of weight loss after drying under controlled temperature and vacuum to determine volatile content including water and residual solvents. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Determination of inorganic residue after high-temperature incineration following sulfuric acid treatment. |
| Specific Optical Rotation | Polarimetry | Measurement of optical activity using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
