Products Description

Kaempferol 98% is a natural flavonol compound. It is a widely distributed polyphenolic antioxidant substance in the plant kingdom. It is a protective active component synthesized by plants to resist ultraviolet rays and fend off pests. The higher the purity, the stronger the biological activity. Kaempferol is abundant in the roots and stems of plants such as Periploca sepium, Ginkgo biloba leaves,Sophora japonica fruit (a type of plant), and Forsythia suspensa. These are preferred raw materials for extraction. The pure kaempferol appears as a fine, non-crystalline, bright yellow or pale yellow crystalline powder. It has no other impurities and is light in texture and has good fluidity. It has a faint grassy fragrance and no other odors. The taste is bitter, but the bitterness is mild and does not irritate the throat. Kaempferol is slightly soluble in hot water and easily soluble in methanol, hot ethanol, glycerin, and other organic solvents. It has strong stability and is not prone to oxidation or decomposition when stored at low temperatures. However, it will change color when exposed to alkali and the activity will be affected in acidic or alkaline environments.
