Citrus bioflavonoids are natural plant compounds found abundantly in citrus peels, pulp and seeds. Alongside vitamin C, they form the characteristic active complex that has made citrus extracts a staple of the nutraceutical industry for decades.

The main families

The most commercially important citrus flavonoids include hesperidin, diosmin, naringin, rutin and quercetin. Each differs in glycoside structure, solubility and application field — from dietary supplements and functional beverages to cosmetics.

• Hesperidin — the dominant flavanone of sweet orange peel, widely used in vascular health formulas.
• Diosmin — a microbially converted form of hesperidin, popular in European leg-health products.
• Naringin — the bitter principle of grapefruit, studied for metabolism support.

When sourcing, buyers should focus on HPLC purity, batch consistency and a supplier who controls the full chain from fruit peel to finished powder — exactly what we do at Green Trading.
