     What is Kaempferol Powder？     

Kaempferol is a natural polyphenol with obvious characteristics, and it is also one of the most common dietary flavonoids. It is widely found in natural plants such as fruits, vegetables and Chinese herbs. Studies have shown that kaempferol plays a neuroprotective role in various nervous system diseases by reducing anti-inflammatory and oxidative stress mediated by microglia activation, which can remove excess free radicals in the human body and prevent oxidative damage to DNA and cells. It has anti-inflammation, anti-aging and other pharmacological effects. In addition, kaempferol also has the function of preventing diabetes, atherosclerosis and osteoporosis. Kaempferol has broad prospects in health food and drug markets. 

     Kaempferol Quality Specification & Standard        

Kintai's High-Purity Kaempferol Powder (CAS: 520-18-3) achieves pharmaceutical-grade purity (≥98% by HPLC), ensuring maximal bioactivity and research reliability. Key benefits include:

Potent Antioxidation: Scavenges DPPH radicals with an IC₅₀ value ≤20 μM, surpassing many common flavonoids in free radical scavenging efficiency.

Anti-Inflammatory Activity: Clinically shown to inhibit COX-2 and TNF-α expression, supporting research in inflammatory disorders (e.g., arthritis, dermatitis).

Metabolic Regulation: Studies indicate Kaempferol may improve insulin sensitivity and lipid profiles, with in vitro data showing 20% reduction in hepatic lipid accumulation at 50 μM.

Enhanced Bioavailability: Ultra-high purity enables better absorption and tissue distribution, with animal studies demonstrating 3-fold higher plasma concentration vs. crude extracts.

     KINTAI's Kaempferol Powder Extracion Process     

After the Sophora japonica pods are crushed, they are extracted with water or ethanol, and then adsorbed with polyamide. After elution, they are separated from other flavonoids by chromatography or separated and purified by high pressure liquid chromatography (HPLC) to obtain high-purity kaempferol powder.

We have multiple international quality certifications including cGMP, HACCP, Halal, ISO9001 and ISO22000, ensuring that every link of our products, from raw material procurement to production and processing to final delivery, meets international standards and customer requirements.

     Benefits of Kaempferol Powder      

1.Anti-inflammatory effect: kaempferol mainly achieves anti-inflammatory effect by inhibiting the expression of inflammatory factors and reducing the production of macrophage derived chemokines and other inflammatory factors, and has specific and strong inhibitory effect on a variety of inflammatory mediators.

2.Neuroprotective effect: kaempferol can play a certain protective effect on nerve damage caused by oxidative stress by inhibiting oxidative stress response, and can be developed and utilized as a potential neuroprotective agent.

3.Diabetes prevention and treatment: kaempferol significantly enhanced the glucose uptake efficiency of 3T3-L1 adipocytes under the action of insulin, showing the potential function of diabetes prevention and treatment. In addition, it helps maintain lipid homeostasis by regulating blood sugar levels and improving insulin sensitivity. Notably, kaempferol has significantly reduced side effects when it performs similar effects to the hypoglycemic drug, providing a new, gentler option for diabetes treatment.​​​​​​​

     Kaempferol Powder Application Fields
