Hesperidin is a natural flavonoid compound extracted from citrus peel and is the core component of citrus bioflavonoids. Due to its excellent antioxidant, anti-inflammatory, and vascular protective activities, such as improving lipid metabolism, enhancing capillary toughness, and regulating blood pressure, it has become an indispensable functional ingredient in dietary supplements, functional foods, and drug formulations.
At the application level, hesperidin has been widely used in cardiovascular health dietary supplements (daily intake of 500mg or more can significantly reduce triglycerides and inflammatory markers), functional foods and beverages (natural antioxidants and enhance vitamin C absorption), drugs (improving venous lymphatic function), and cosmetics (anti-aging, soothing, and repairing).
So, how to distinguish the quality differences of high-purity hesperidin? The detection standards are the core basis: key indicators include HPLC content determination (≥ 95% or ≥ 98%), heavy metal residue (≤ 0.1mg/kg), solvent residue (≤ 100ppm), and microbial limit. When purchasing, it is necessary to verify the third-party COA report and clearly indicate the testing method. Purity directly determines the use - ≥ 95% is suitable for drugs and clinical grade supplements, and 80% specification is mostly used for ordinary food. The current industry trend shows that standardized high-purity hesperidin is becoming mainstream, and the supplier's full traceability system and pesticide residue control capability are the key to selection.
