- Product Description
The quercetin in Sophora Japonica extract is a high-quality bioactive that can be used in drugs and supplements.
Sophora Japonica Extract Quercetin, is a natural flavonoid compound extracted from the pods of Sophora japonica flowers. Shaanxi Hongda utilizes its core "directional gradient crystallization + multi-stage membrane filtration" technology to ensure a quercetin content of 95%/98% (HPLC). We have also solved the common problems of "heavy metal accumulation" and "excessive ash content" in natural extracts.
We use supercritical carbon dioxide to extract our quercetin powder, thus there are no solvents used. The testing with high-performance liquid chromatography (HPLC) confirms that the substance is at least 95% pure, which is the standard for pharmaceutical-grade substances. It is generally known that quercetin extract is easy for the body to absorb. It helps the heart, keeps skin healthy, and boosts the immune system. Customers can choose how they want our powder to be made, and it can be turned into capsules, premixed powders, or tablets.

Important Benefits
- Extremely High "Pharmacopoeia-Grade" Purity and Stability: Shaanxi Hongda performs batch-to-batch impurity spectrum clearing scans to ensure no cross-interference from isorhamnetin and similar substances.
- Exclusive "Ultra-fine Powdering" and Optimized Absorption Rate: We control the particle size below 5μm through physical modification, and actual tests show that its dissolution rate in the intestine is increased by approximately 30%, effectively solving the "perceived absorption rate" pain point for customers in capsule or tablet development.
- 100% Green Solvents and "Clean Label" Guarantee: We use purified water and pharmaceutical-grade ethanol as extraction media, eliminating the residue of carcinogens such as methanol and benzene.
- Tested in a lab for strength and consistency, this product has 98% quercetin.
- Natural and non-GMO: made from farms that have been certified as being good for the environment.
- Better Bioavailability: The formulations are made to make it easier for the body to absorb them.
- Custom Solutions: mixtures, concentrations, and formats (such powder and capsules) that are customized particularly for you.
