Manufacturing Quality Control of ALPHA-CARYOPHYLLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID or MS detection | Quantifies ALPHA-β-caryophyllene peak area relative to internal/external standard using retention time and calibration curve. |
| Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirms molecular structure by matching characteristic absorption bands (e.g., C=C, C–H stretch) to reference spectrum. |
| Specific Optical Rotation | [α]D | Measures rotation of plane-polarized light at 589 nm to verify chiral integrity and enantiomeric composition. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents (e.g., hexane, ethanol) based on headspace equilibrium and GC peak integration. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines trace water via electrochemical iodine generation and stoichiometric reaction with water. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects and quantifies trace metal impurities by atomization, ionization, and mass-to-charge ratio discrimination. |
| Acid Value | Potentiometric Titration with KOH in isopropanol | Measures free carboxylic acid content via neutralization stoichiometry, detected by pH inflection point. |
| Peroxide Value | Iodometric Titration | Quantifies hydroperoxides by iodide oxidation to iodine, followed by titration with standardized sodium thiosulfate. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness/browning intensity against platinum-cobalt standards or absorbance at specified wavelength. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation & Weighing) | Determines residue after controlled evaporation of sample under inert atmosphere and drying to constant weight. |
| Related Substances (Impurities) | Gas Chromatography–Mass Spectrometry (GC-MS) | Separates and identifies structurally related terpenoid impurities (e.g., α-humulene, β-farnesene) by retention time and mass spectral match. |
| Density at 20 °C | Oscillating U-tube Densitometry | Measures mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 °C | Abbe Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement of monochromatic light (589 nm). |
