Kaempferide Cas No. 491-54-3

ʻO ka wehewehe pōkole:

Ua ʻike ʻia ʻo Kaempferol ʻo "caphenyl alcohol".ʻO Flavonoids kekahi o nā waiʻona.Ua ʻike ʻia mai ke kī i ka makahiki 1937. Ua hoʻokaʻawale ʻia ka hapa nui o nā glycosides i ka makahiki 1953.

Hoʻohui nui ʻia ʻo Kaempferol i ke kī me ka glucose, rhamnose a me ka galactose e hana i nā glycosides, a he kakaikahi nā mokuʻāina manuahi.ʻO ka maʻiʻo he 0.1% ~ 0.4% o ke kaumaha maloʻo o ke kī, a ʻoi aku ka kiʻekiʻe o ka puna puna ma mua o ke kī o ke kauwela.ʻO ka kaempferol glycosides i hoʻokaʻawale ʻia he kaempferol-3-rhamnoside, kaempferol-3-rhamnoside, kaempferol-3-glucoside, kaempferol triglucoside, a pēlā aku.Pāʻani lākou i kahi hana i ka hoʻokumu ʻana i ke kala ʻōmaʻomaʻo sopa.I ka hana ʻana o ke kī, ua hoʻoheheʻe ʻia ka kaempferol glycoside ma lalo o ka hana a ka wela a me ka enzyme e hoʻokuʻu ai i kaempferol a me nā mea like ʻole e hōʻemi i ka ʻawaʻawa.
