Industrial Applications of Polydatin
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antioxidant; active pharmaceutical ingredient in anti-inflammatory drugs | Extracted from Japanese knotweed; purified via solvent extraction or chromatography |
| Food Industry | Natural colorant; functional food additive | Extracted from Japanese knotweed; subjected to filtration and concentration |
| Cosmetics | Ingredient in skincare and anti-aging products | Extracted from Japanese knotweed; refined for use in formulations |
Manufacturing Quality Control of Polydatin
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column, with methanol-water or acetonitrile-water containing acid (e.g., phosphoric acid, formic acid) as mobile phase for gradient or isocratic elution. The peak area of polygonin is detected by UV detector (commonly set at 306 nm or 290 nm), and content is calculated using an external standard method. This method is sensitive and accurate, and commonly used in pharmacopoeias. |
| Thin-Layer Chromatography Identification | Thin-Layer Chromatography (TLC) | Silica gel G plates are used, with developing systems such as ethyl acetate-methanol-water (e.g., 8:2:1). Visualization is achieved by heating after spraying with 10% sulfuric acid in ethanol solution, or by observing fluorescent spots under UV light, for qualitative identification of polygonin. |
| Purity Test | HPLC | Basing on the assay method, purity is evaluated through peak purity analysis of the main component, number and area of impurity peaks. Good separation between the main peak and impurity peaks is typically required, with total impurities meeting specified limits (e.g., ≤5%). |
| Moisture Content | Loss on Drying or Karl Fischer Titration | Loss on drying: sample is dried at 105°C to constant weight and weight loss is calculated. Karl Fischer method is suitable for trace moisture detection, offering higher precision, especially for hygroscopic samples. |
| Total Ash and Acid-Insoluble Ash | Ash Content Determination | The sample is incinerated at high temperature (500–600°C) to constant weight to determine total ash. The residue is then treated with hydrochloric acid to determine acid-insoluble ash, which helps control inorganic impurities. |
| Heavy Metals and Hazardous Elements | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After sample digestion, levels of elements such as lead, cadmium, arsenic, mercury, and copper are measured to ensure compliance with safety limits for herbal medicines or dietary supplements. |
| Pesticide Residues | Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) | Sample is pre-treated (e.g., QuEChERS method) to detect residues of organochlorine, organophosphate, and other pesticides, ensuring raw material safety. |
| Microbial Limits | Microbial Limit Test | In accordance with the requirements of the Chinese Pharmacopoeia, tests are conducted for total aerobic microbial count, mold and yeast count, and specified pathogens (e.g., Escherichia coli, Salmonella), to ensure microbiological safety of the product. |
| Exogenous Contaminants (e.g., Mycotoxins) | HPLC or LC-MS/MS | Detection of mycotoxins such as aflatoxins to ensure safety during raw material storage. |
