Kempferol je prirodni flavonol iz porodice flavonoida.

Hemija

Kempferol je žuta kristalna materija sa tačkom ključanja od 276–278 °C. On je neznatno rastvoran u vodi, ali je rastvoran u vrućem etanolu i dietil etru.

Prirodna pojava

On može da bude izolovan iz čaja,^[5] broklija, Delphinium, hamamelisa, grejpfruta, kupusa, kelja, pasulja, endivije, praziluka, paradajza, jagoda, grožđa, Prokelja, jabuka, i drugih biljnih izvora.

Kempferol i njegovi glukozidi se mogu izolovati iz metanolnog ekstrakta lista paprati Phegopteris connectilis.^[6]
