Quercetin factory supplier bulk Wholesale Extract factory

  1. Nome inglese: Quercetin (say “kwur-suh-tin”—it’s a flavonoid, the same family of nutrients that makes apples crunchy and onions flavorful!)
  1. Specificazione
    • Purezza: ≥ 95% (HPLC tested—super pure, no random plant bits or fillers)
    • Solubilità: Slightly soluble in water; dissolves well in ethanol and oils (works great in supplements or oil-based formulas)
    • Punto di fusione: Around 316–320°C (stays stable in most cooking or supplement-making processes)
    • Perdita all'essiccazione: ≤ 0.5% (keeps it dry, no clumping or losing its nutrient power)
    • metalli pesanti: ≤ 10 ppm (totalmente sicuro per uso orale, soddisfa rigorosi standard alimentari/di benessere)
  1. Aspetto: Yellow to pale yellow powder with a mild, earthy plant smell—decisamente no chocolate aroma! It’s got that subtle, fresh scent of the fruits/veggies it comes from.
  1. N. CAS: 117-39-5 (this is the real CAS for quercetin, not that cocoa butter one—huge difference!)
  1. Tempi di consegna: 3-7 giorni lavorativi (lo teniamo regolarmente in magazzino, quindi non dovrai aspettare molto per acquistarlo)
  1. Pacchetto: Small sizes: 1g/10g/100g light-resistant glass vials (protects its color and potency); bulk: 1kg aluminum tins or 25kg sealed drums (light-blocking—sunlight fades its benefits!)
  1. Mercato principale: Europe, North America, Asia—anywhere people care about natural antioxidants (super popular for immune and heart wellness!)
  1. Scenari applicativi

Caratteristiche principali

  • Centrale elettrica antiossidante: One of the most common flavonoids in plants—helps fight free radicals (the stuff that damages cells over time)

Quercetin: The Grasp Flavonoid Powering Subsequent-Gen Nutraceuticals & Therapeutics | Supplier & Manufacturer

1. Che cos'è la quercetina?

La quercetina è una flavonolo dietetico belonging to the polyphenol subclass, characterised by its pentahydroxyflavone construction (3,3′,4′,5,7-pentahydroxyflavone). As a potent redox cofactor, it demonstrates distinctive free radical scavenging capability (ORAC worth: 14,400 μmol TE/g) and metal-chelating properties. This plant-derived bioactive modulates over 120 mobile signaling pathways, together with NF-κB, Nrf2, and SIRT1, positioning it as a cornerstone of phytonutrient analysis.
