Kaempferol

Kaempferol (3,4′,5,7-tetrahydroxyflavone) is a natural flavonol, a type of flavonoid, found in a variety of plants and plant-derived foods, including kale, beans, tea, spinach, and broccoli. It is also found in propolis extracts. Kaempferol is a yellow crystalline solid with a melting point of 276–278 °C (529–532 °F). It is slightly soluble in water and highly soluble in hot ethanol, ethers, and DMSO. Kaempferol is named for 17th-century German naturalist Engelbert Kaempfer.

Natural occurrence
Kaempferol is a secondary metabolite found in many plants, plant-derived foods, and traditional medicines. The total average intake of flavonols and flavones in a normal diet is estimated as 23 mg/day, to which kaempferol contributes approximately 17%. Common foods that contain kaempferol include: apples, grapes, Euphorbia pekinensis, Moringa oleifera, Rosmarinus officinalis, ==Biosynthesis==
Biosynthesis
The biosynthesis of kaempferol occurs in four major steps: The phenylpropanoid pathway is the pathway that converts phenylalanine into tetrahydroxychalcone. Flavonols, including kaempferol, are products of this pathway. ==Notes==
