Kaempferide Cas No. 491-54-3

Tsanangudzo Pfupi

Kaempferol inozivikanwawo se "camphenyl doro".Flavonoids ndechimwe chezvinwiwa zvinodhaka.Yakaonekwa kubva kune tii muna 1937. Zvizhinji zve glycosides zvakaparadzaniswa muna 1953.

Kaempferol mutii inonyanya kusanganiswa neglucose, rhamnose uye galactose kuumba glycosides, uye kune mashoma emahara nyika.Zviri mukati ndeye 0.1% ~ 0.4% yehuremu hwakaoma hwetii, uye chitubu tii yakakwirira kupfuura tei yezhizha.Iyo yakaparadzana kaempferol glycosides inonyanya kusanganisira kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, etc. Mazhinji acho makristasi eyero, anogona kunyungudika mumvura, methanol uye ethanol.Ivo vanoita rimwe basa mukugadzira green tea soup color.Mukuita kwekugadzira tii, kaempferol glycoside ine chikamu hydrolyzed pasi pechiito chekupisa uye enzyme kusunungura mu kaempferol uye shuga dzakasiyana kuderedza kumwe kuvava.
