Kaempferide Cas No. 491-54-3

Lus piav qhia luv luv:

Kaempferol tseem hu ua "camphenyl cawv".Flavonoids yog ib qho ntawm cov cawv.Nws tau tshawb pom los ntawm cov tshuaj yej xyoo 1937. Feem ntau ntawm cov glycosides raug cais tawm hauv xyoo 1953.

Kaempferol hauv tshuaj yej feem ntau ua ke nrog qabzib, rhamnose thiab galactose los tsim glycosides, thiab muaj qee lub xeev dawb.Cov ntsiab lus yog 0.1% ~ 0.4% ntawm qhov hnyav qhuav ntawm cov tshuaj yej, thiab cov tshuaj yej caij nplooj ntoos hlav yog siab tshaj lub caij ntuj sov tshuaj yej.Cov cais kaempferol glycosides feem ntau muaj xws li kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, thiab lwm yam. Lawv feem ntau yog cov muaju daj, uas tuaj yeem yaj hauv dej, methanol thiab ethanol.Lawv ua lub luag haujlwm hauv kev tsim cov tshuaj yej ntsuab kua zaub xim.Hauv cov txheej txheem ntawm kev tsim tshuaj yej, kaempferol glycoside yog ib nrab hydrolyzed nyob rau hauv qhov kev txiav txim ntawm tshav kub thiab enzyme kom dawb rau hauv kaempferol thiab ntau yam suab thaj kom txo tau ib co iab.
