Kaempferide Cas No. 491-54-3

Inkcazelo emfutshane:

I-Kaempferol ikwabizwa ngokuba yi "camphenyl alcohol".I-Flavonoids yenye yee-alcohols.Kwafunyaniswa kwi-tea ngo-1937. Uninzi lwe-glycosides lwalulodwa ngo-1953.

I-Kaempferol kwiti idityaniswa kakhulu ne-glucose, i-rhamnose kunye ne-galactose ukwenza i-glycosides, kwaye zimbalwa iindawo ezikhululekile.Umxholo ngu-0.1% ~ 0.4% wobunzima obomileyo beti, kwaye iti yasentwasahlobo iphezulu kuneti yehlobo.I-kaempferol glycosides eyahluliweyo iquka i- kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, njl njl. Uninzi lwazo ziikristale ezityheli, ezinokunyibilika emanzini, i-methanol kunye ne-ethanol.Badlala indima ethile ekubunjweni kombala wesobho yeti eluhlaza.Kwinkqubo yokwenza iti, i-kaempferol glycoside ifakwe i-hydrolyzed ngokuyinxenye phantsi kwesenzo sobushushu kunye ne-enzyme ukukhulula kwi-kaempferol kunye neeshukela ezahlukeneyo ukunciphisa ubukrakra.
