Industrial Applications of FLAVONE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Used as a pharmaceutical intermediate in the synthesis of flavonoid-based drugs exhibiting antioxidant, anti-inflammatory, and antimicrobial activities | Chemical synthesis, separation, and purification |
| Food Industry | Used as a natural antioxidant in oils and dietary supplements to prevent oxidative degradation | Extraction (e.g., from plant sources), purification, and formulation addition |
| Cosmetics Industry | Used as an active ingredient in skincare products to deliver antioxidant, anti-aging, and UV-protective effects | Extraction, purification, and compounding with other ingredients |
| Research & Testing | Used as a reference standard or analytical standard in analytical chemistry for qualitative and quantitative analysis of other flavonoid compounds | High-purity synthesis and purification |
Manufacturing Quality Control of FLAVONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Quantitative analysis based on the characteristic absorption peaks of flavonoids at specific wavelengths (typically 270–280 nm and 350–360 nm). The aluminum complex colorimetric method is often used to enhance sensitivity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Separation of individual flavonoids using a reversed-phase column (e.g., C18), followed by detection with a UV or diode array detector (DAD), enabling simultaneous and accurate quantification of multiple flavonoid components. |
| Content Determination | Ultra-Performance Liquid Chromatography (UPLC) | An upgraded version of HPLC utilizing smaller particle-sized stationary phases and high-pressure systems to improve separation efficiency and analysis speed, suitable for rapid analysis of trace flavonoids in complex samples. |
| Component Identification and Qualitative Analysis | Liquid Chromatography-Mass Spectrometry (LC-MS) | Combines the separation capability of liquid chromatography with the structural identification power of mass spectrometry for determining molecular weights and elucidating structures of flavonoid compounds, particularly useful for identifying unknown components. |
| Antioxidant Activity | DPPH Radical Scavenging Assay | Evaluates the antioxidant capacity of flavonoid extracts by measuring the change in absorbance of DPPH radicals at 517 nm, commonly used for activity-related quality assessment. |
| Purity Check | Thin-Layer Chromatography (TLC) | Separation of flavonoid components on a silica gel plate using a suitable mobile phase; visualization via coloring reagents to observe the number of spots and Rf values for preliminary assessment of sample purity and component consistency. |
| Simultaneous Analysis of Multiple Components | Multi-Component HPLC Fingerprinting | Establishment of an HPLC fingerprint profile for flavonoid-containing herbs or formulations, evaluating product quality stability and batch-to-batch consistency through matching of common peaks. |
