Industrial Applications of Myricitrin
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Research on antioxidant, anti-inflammatory, and antitumor active ingredients | Extracted from plants such as Myrica rubra and purified via chromatographic separation for drug development or use as lead compounds |
| Food | Natural antioxidant and functional food additive | Extracted from Myrica rubra fruit for enhancing food stability or developing health-promoting foods |
| Cosmetics | Active ingredient for anti-aging, skin-lightening, and UV protection | Incorporated into skincare formulations to enhance cutaneous antioxidant capacity through synergistic formulation |
| Research | Bioactivity studies and metabolic pathway probing | Used as reference standard or reagent in cell-based assays, animal models, and molecular mechanism studies |
Manufacturing Quality Control of Myricitrin
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column with gradient elution employing methanol-water or acetonitrile-water containing acid (e.g., phosphoric acid or formic acid) as mobile phase. Detection is performed using a UV detector at approximately 254–370 nm to quantitatively analyze myricetin content, offering high separation efficiency and good reproducibility. |
| Purity Test | High-Performance Liquid Chromatography (HPLC) | Evaluates sample purity based on the main peak purity and the number/area of impurity peaks in the HPLC chromatogram. Typically requires main peak purity >95% or compliance with pharmacopoeial standards. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Myricetin exhibits characteristic absorption peaks at 250–280 nm and 350–370 nm. Preliminary identification is achieved by comparing the UV spectra of the test sample with that of the reference standard. |
| Thin-Layer Chromatography (TLC) | Uses silica gel plates developed with an appropriate mobile phase (e.g., ethyl acetate-methanol-water), followed by visualization and comparison of spot positions (Rf values) with those of reference substances for rapid qualitative identification. | |
| Liquid Chromatography-Mass Spectrometry (LC-MS) | Combines retention time and characteristic mass spectral ions (e.g., [m/z] 317 [M-H]⁻) to confirm molecular weight and structural identity of myricetin. Highly specific and suitable for identification in complex matrices. | |
| Dissolution/Release Rate | UV Spectrophotometry or HPLC | For myricetin formulations (e.g., tablets, capsules), dissolution testing is conducted using a dissolution apparatus in specified media, followed by quantification via UV or HPLC to evaluate in vitro release performance. |
| Residual Solvents | Gas Chromatography (GC) | Detects residual organic solvents (e.g., methanol, ethanol, acetone) possibly remaining from extraction processes. Controlled according to ICH guidelines to ensure product safety. |
| Moisture Content | Karl Fischer Titration | Precisely measures moisture content in the sample to prevent hygroscopic effects on stability and quantitative accuracy. Commonly used in quality control of active pharmaceutical ingredients. |
| Heavy Metals and Toxic Elements | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Determines levels of heavy metals such as lead, cadmium, arsenic, and mercury to ensure compliance with safety limits for pharmaceutical or food additive use. |
| Microbial Limits | Microbial Limit Test | Performs total aerobic microbial count, mold and yeast count, and tests for specified pathogens (e.g., Escherichia coli, Salmonella) according to the Chinese Pharmacopoeia or relevant standards to ensure microbiological safety of the product. |
