Manufacturing Quality Control of Coumalic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | A reversed-phase C18 column is used, with methanol-water or acetonitrile-water (containing a small amount of acid such as phosphoric acid or acetic acid) as the mobile phase. Detection is performed at 290–310 nm using a UV detector, and quantification of coumaric acid is achieved via external or internal standard methods. This method offers high sensitivity and good reproducibility, and is suitable for assay analysis in raw materials and pharmaceutical formulations. |
| Purity Test | High-Performance Liquid Chromatography (HPLC) | Basing on the assay method, purity is evaluated by peak area normalization to assess the main peak's purity, detecting potential impurity peaks (e.g., other phenolic acids), and determining whether the sample meets purity specifications. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Coumaric acid exhibits characteristic absorption peaks near 290 nm and 310 nm. Preliminary identification is achieved by comparing the UV absorption spectra of the test sample with that of the reference standard. This method is simple and commonly used for rapid qualitative analysis. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | The infrared absorption spectrum of the sample is measured to identify characteristic functional groups of coumaric acid, such as carboxyl group (~1700 cm⁻¹), benzene ring (~1600, 1500 cm⁻¹), and double bond (~1630 cm⁻¹), for structural verification. |
| Residual Solvents | Gas Chromatography (GC) | If coumaric acid is extracted or purified using organic solvents, residual solvents (e.g., methanol, ethanol, ethyl acetate) must be tested. Capillary column GC with FID detection is employed, following pharmacopoeial methods for limit control. |
| Moisture Content | Karl Fischer Titration | Accurately determines the moisture content in the sample to prevent hygroscopic effects on stability and quality assessment. Suitable for quality control of powdered coumaric acid raw material. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Determines residual heavy metals such as lead, cadmium, arsenic, and mercury to ensure compliance with safety standards for pharmaceutical or food additive use. Samples require digestion prior to analysis. |
| Microbial Limits | Microbial Limit Test | Performs total aerobic microbial count, mold and yeast count, and tests for specified microorganisms (e.g., Escherichia coli, Salmonella) according to the Chinese Pharmacopoeia or relevant standards to ensure microbiological safety of the product. |
