Manufacturing Quality Control of 579-44-2
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Physical Characteristic Identification | Sensory Examination | Observe the appearance, color, odor, and texture of benzoin. Genuine benzoin appears as irregular lumps ranging from pale yellow to brown, with a characteristic aroma; when burned, it produces black smoke and oil exudation. |
| Identification (Chemical Reaction) | Ferric Chloride Test | Dissolve the sample in ethanol, then add ferric chloride reagent; observe for the formation of a blue-violet color to detect phenolic components (e.g., benzoic acid). |
| Identification (Thin Layer Chromatography) | TLC (Thin Layer Chromatography) | Use a silica gel plate with an appropriate mobile phase (e.g., toluene-ethyl acetate-formic acid) for development. Spray with a color reagent (e.g., 10% sulfuric acid in ethanol) and heat to visualize spots; compare Rf values with reference standards. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Determine the content of major active components (e.g., benzoic acid, cinnamic acid). Use a C18 column with a UV detector and external standard quantification. |
| Moi sture Content Determination | Drying Method or Karl Fischer Method | Drying method: Measure weight loss after constant weight at 105°C; Karl Fischer method is suitable for trace moisture determination with higher precision. |
| Ash Content Determination | Incineration Method (Total Ash, Acid-Insoluble Ash) | Incinerate the sample at high temperature (500–600°C) until constant weight, then calculate the percentage of residual ash relative to the sample weight to assess inorganic impurity levels. |
| Extractable Content | Alcohol-Soluble Extracts Determination | Use ethanol as the solvent, extract via hot maceration, evaporate the solvent, and weigh the residue to calculate the percentage of soluble components. |
| Impurity Check | Visual/Sieving Method + Microscopic Examination | Inspect for non-medicinal impurities such as bark, sand, or foreign matter; microscopic analysis may be used when necessary to identify adulterants. |
| Volatile Oil Content | Steam Distillation Method | Applicable to benzoin containing volatile components; collect volatile oil via steam distillation and measure volume or weight. |
| Microbial Limit Test | Microbial Culture Method | Conduct tests for aerobic bacteria, molds, Escherichia coli, etc., in accordance with the requirements of the Chinese Pharmacopoeia to ensure compliance with hygiene standards. |
