Quercetin is extracted from sophora japonica bud. Chemically known as 3,3',4',5,7-pentahydroxyflavone, quercetin is one of the most extensively studied flavonoids for its biological activities and potential health applications.

Our quercetin is available in a 95% purity grade (HPLC-verified), sourced from natural plant materials and processed through controlled extraction to ensure consistent quality, batch-to-batch reliability, and full regulatory documentation support.

Formulation Considerations for 95% Quercetin Powder

1) For Capsules and Tablets:

• Blend directly with appropriate excipients (microcrystalline cellulose, etc.)

• Ensure uniform mixing for consistent dosing

• Dissolution enhancement: lactose monohydrate (at 10% concentration) has been shown to improve quercetin tablet dissolution time, suggesting stable tablet formulations can be developed with appropriate excipient selection

2) For Liquid Formulations:

• Pre-dissolve in ethanol or DMSO before incorporating into aqueous systems

• Alternative approaches: use of biocompatible solvents such as choline-tryptophan ionic liquids has been shown to enhance quercetin solubility in aqueous systems

• Protect from light using amber packaging

3) For Cosmetic Formulations:

• Incorporate into the oil phase or use appropriate solubilizers

• Consider advanced delivery systems (liposomes, nanoparticles) to enhance bioavailability
