Kaempferide Cas Nke 491-54-3

Nkọwa dị mkpirikpi:

A na-akpọkwa Kaempferol dị ka "camphenyl alcohol".Flavonoids bụ otu n'ime mmanya na-egbu egbu.Achọpụtara ya na tii na 1937. Ọtụtụ n'ime glycosides dịpụrụ adịpụ na 1953.

Kaempferol na tii na-ejikọtakarị ya na glucose, rhamnose na galactose iji mepụta glycosides, ma enwere steeti ole na ole n'efu.Ọdịnaya bụ 0.1% ~ 0.4% nke akọrọ dị arọ nke tii, na mmiri tii dị elu karịa tii tii.Ndị kewapụrụ kaempferol glycosides bụ isi gụnyere kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, wdg. Ọtụtụ n'ime ha bụ kristal edo edo, nke nwere ike ịgbaze na mmiri, methanol na ethanol.Ha na-ekere òkè ụfọdụ na nhazi agba ofe tii green.N'ime usoro ịme tii, kaempferol glycoside bụ akụkụ nke hydrolyzed n'okpuru ọrụ okpomọkụ na enzyme iji banye na kaempferol na shuga dị iche iche iji belata ụfọdụ obi ilu.
