Kaempferol waxa kale oo loo yaqaan "camphenyl alcohol".Flavonoids waa mid ka mid ah khamriga.Waxaa laga helay shaaha 1937. Inta badan glycosides ayaa la go'doomiyay 1953.
Kaempferol ee shaaha waxaa inta badan lagu daraa glucose, rhamnose iyo galactose si ay u sameeyaan glycosides, waxaana jira dhowr gobol oo bilaash ah.Waxa ku jira 0.1% ~ 0.4% miisaanka engegan ee shaaha, shaaha gu'ga ayaa ka sarreeya shaaha xagaaga.Kaempferol glycosides ee kala go'ay waxaa ka mid ah kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, iwm. Intooda badan waa crystals jaale ah, kuwaas oo lagu milmi karo biyaha, methanol iyo ethanol.Waxay door gaar ah ka ciyaaraan samaynta midabka maraq shaaha cagaaran.Habka samaynta shaaha, kaempferol glycoside waxaa qayb ahaan hydrolyzed hoos ficilka kulaylka iyo ensaymes si ay u xoreeyaan kaempferol iyo sonkor kala duwan si loo yareeyo qaar ka mid ah qadhaadhka.
