Kaempferol izwi kandi nka “camphenyl alcool”.Flavonoide ni imwe muri alcool.Yagaragaye mu cyayi mu 1937. Hafi ya glycoside yitaruye mu 1953.
Kaempferol mu cyayi ahanini ihujwe na glucose, rhamnose na galactose kugirango ikore glycoside, kandi hariho leta nkeya.Ibirimo ni 0.1% ~ 0.4% byuburemere bwicyayi cyumye, kandi icyayi cyimpeshyi kiri hejuru yicyayi.Gutandukanya kaempferol glycoside harimo cyane cyane kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, nibindi byinshi muribyo ni kristu yumuhondo, ishobora gushonga mumazi, methanol na Ethanol.Bafite uruhare runini mugushinga ibara ryicyayi kibisi.Muburyo bwo gukora icyayi, kaempferol glycoside iba igice cya hydrolyz munsi yubushyuhe nubushuhe kugirango ibe muri kaempferol hamwe nisukari zitandukanye kugirango bigabanye umururazi.
