Kaempferide Cas No. 491-54-3

Tlhaloso e Khutšoanyane:

Kaempferol e boetse e tsejoa e le "camphenyl alcohol".Flavonoids ke e 'ngoe ea lino tse tahang.E ile ea fumanoa ho tloha tee ka 1937. Boholo ba li-glycosides li ne li arohane ka 1953.

Kaempferol ka tee hangata e kopantsoe le tsoekere, rhamnose le galactose ho theha glycosides, 'me ho na le linaha tse' maloa tsa mahala.Likahare ke 0.1% ~ 0.4% ea boima bo omileng ba tee, 'me tee ea selemo e phahame ho feta ea lehlabula.The arohaneng kaempferol glycosides haholo-holo kenyeletsa kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, joalo-joalo Bongata ba tsona ke likristale tse mosehla, tse ka qhibilihang ka metsing, methanol le ethanol.Ba phetha karolo e itseng ho thehoeng ha 'mala oa sopho ea tee e tala.Ts'ebetsong ea ho etsa tee, kaempferol glycoside e na le hydrolyzed ka mokhoa o itseng tlas'a ts'ebetso ea mocheso le enzyme ho lokolla kaempferol le tsoekere e fapaneng ho fokotsa bohloko bo itseng.
