Quercetin Dihydrate Powder 98%：Overview

Quercetin Dihydrate Powder 98% is a high-purity flavonoid compound derived from natural plant sources, widely recognized for its potent antioxidant and anti-inflammatory properties. It is commonly used in dietary supplements, nutraceuticals, and functional foods to support overall wellness, cardiovascular health, and immune function.

Our Manufacturing Process

1. Raw Material Selection:

    · High-quality plant sources rich in quercetin (e.g., Sophora japonica, onions, or other flavonoid-rich plants) are selected.

    · Raw materials are inspected for purity, moisture content, and absence of contaminants.

2. Extraction Stage:

    · Plant material is dried and powdered.

    · Quercetin is extracted using solvents like ethanol, water, or a mixture under controlled temperature and pH.

    · Extraction is repeated to maximize yield.

3. Filtration & Concentration:

    · The extract is filtered to remove insoluble plant matter.

    · Filtrate is concentrated under vacuum evaporation to remove excess solvent while preserving active compounds.

4. Purification Stage:

    · Crude quercetin is purified using techniques like:

            Recrystallization (to obtain quercetin dihydrate crystals)

            Column chromatography (if higher purity is required)

    · Impurities and unwanted compounds are separated during this stage.

5. Drying:

    · Purified quercetin dihydrate is dried using vacuum drying or spray drying to achieve a stable crystalline powder.

    · Moisture content is controlled (≤5%) to ensure shelf stability.

6. Sieving & Milling:

    · Dried powder is sieved to achieve uniform particle size (commonly 80–100 mesh).

    · Milling may be performed to reduce particle size for better solubility and blending.

7. Quality Control (QC):

    · Samples are tested for assay (≥98%), moisture, heavy metals, microbial limits, and particle size.

    · Only batches passing QC are approved for packaging.

8. Packaging & Storage:

    · Powder is packed in airtight, moisture-resistant containers.

    · Stored in a cool, dry place away from sunlight to maintain stability.
