Products Description

Kaempferol 50% is a high-purity natural flavonoid monomer raw material with the standard chemical name 3,5,7,4'-tetrahydroxyflavone and CAS No. 520-18-3. It is a widely applied natural plant active ingredient in the functional raw material industry. Our product is refined from high-quality Sophora japonica pods through mature plant extraction, separation and purification, and recrystallization processes. The whole production process is strictly controlled, with the purity stably reaching above 50% tested by HPLC, featuring extremely low impurity content and excellent batch stability. The Kaempferol 50% appears as pale yellow to bright yellow fine crystalline powder with a slight natural plant odor and no peculiar smell or caking. It maintains stable physical and chemical properties at room temperature, only sensitive to strong light and high temperature, and slight oxidative discoloration may occur under long-term harsh storage conditions. Slightly soluble in cold water, it is soluble in hot ethanol, ether and alkaline aqueous solutions. The unique polyhydroxy active groups in its molecular structure are the core basis for its various biological activities. As a pure natural plant extract, it contains no synthetic additives, pigments or preservatives. Complying with universal production specifications for food, cosmetic and pharmaceutical raw materials and passing multiple quality tests, it features high safety and compliance, adapting to raw material procurement and processing needs in global markets, and serving as a high-quality natural raw material for deep processing industries.

Function

Antioxidation and Anti-aging: Kaempferol features outstanding natural antioxidant activity. It can effectively scavenge excess free radicals in organisms and product systems, block the continuous progression of lipid peroxidation, reduce cell damage caused by oxidative stress, stabilize the complete structure of cells and biological membranes, and fundamentally delay the oxidative aging of human body functions and raw material systems.
Mild Anti-inflammatory and Soothing Effect: It can accurately regulate inflammation-related signaling pathways in the body, inhibit the generation and release of various inflammatory factors and mediators, and effectively relieve tissue damage and discomfort caused by various inflammatory reactions. With mild and non-irritating anti-inflammatory properties, it fully meets the safety standards for the development of various functional products.
Cardiovascular Protection: It repairs damaged vascular endothelial cells, optimizes the overall physiological state of blood vessels, balances blood lipid metabolism, inhibits abnormal platelet aggregation, reduces potential thrombosis risks, and assists in maintaining the stability and health of the cardiovascular system.
Liver and Nerve Protection: It exerts a good repairing effect on the liver, alleviating liver damage caused by chemical substances and external stimuli, and ensuring the normal metabolism and detoxification functions of the liver. Meanwhile, it relieves oxidative damage to nerve cells, protects the normal operation of the nervous system and improves the activity of nerve cells.
Antibacterial and Antiviral Activity: It has broad-spectrum antibacterial and antiviral properties, which can effectively inhibit the activity of various common pathogenic bacteria and viruses, reduce the negative impact of harmful microorganisms, and enhance the protection capability of products and organisms.
Bidirectional Immune Regulation: It gently regulates the body's immune function. It not only enhances the basic immune resistance and body defense capability, but also inhibits excessive immune reactions and avoids discomfort caused by immune disorders, so as to balance the body's immune state.

Application

Dietary Health Product Industry: It can be used as a core natural raw material for the production and research and development of various dietary supplements and functional health products, and is widely applicable to the raw material formula system of high-end health care products.
