I-Kaempferide Cas No. 491-54-3

Incazelo emfushane:

I-Kaempferol yaziwa nangokuthi "i-camphenyl alcohol".I-Flavonoids ingenye yeziphuzo ezidakayo.Yatholwa etiyeni ngo-1937. Iningi lama-glycosides lahlukaniswa ngo-1953.

I-Kaempferol etiyeni ihlanganiswe kakhulu ne-glucose, i-rhamnose ne-galactose ukuze yakhe i-glycosides, futhi kunezifunda ezimbalwa zamahhala.Okuqukethwe kungu-0.1% ~ 0.4% wesisindo esomile setiye, kanti itiye lasentwasahlobo liphakeme kunetiye lasehlobo.I- kaempferol glycosides ehlukanisiwe ikakhulukazi ihlanganisa i- kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, njll. Iningi lawo amakristalu aphuzi, angancibilika emanzini, i-methanol ne-ethanol.Badlala indima ethile ekwakhekeni kombala wesobho letiye eliluhlaza.Enqubweni yokwenziwa kwetiye, i-kaempferol glycoside ifakwa i-hydrolyzed kancane ngaphansi kwesenzo sokushisa kanye ne-enzyme ukuze ikhulule ku-kempferol noshukela ohlukahlukene ukunciphisa ukufutheka okuthile.
