Hence, in this study, we investigated kaempferol, a potent naturally occurring antioxidant for its effectiveness against experimentally induced MI in rats.
cearensis is basically composed of coumarin, responsible for its peculiar flavour, and also of flavonoids isokampferideo, kaempferol and afrormosin (BRAVO et al.

The extraction of some flavonoids (quercetin, kaempferol, and apigenin) was performed as described by Hertog et al.
A recent study examined the kaempferol intake of more than 66,000 women.
The standards used in this study were gallic acid, trans sinapic acid, chlorogenic acid, caffeic acid, ferulic acid, vanillic acid, [rho]-coumaric acid, catechin, epicatechin, rutin, myricetin, quercetin, naringenin and kaempferol.
In tea, prominent phytochemicals are theaflavin, thearubingins and theabrownin belong to flavanols while flavonols are composed of quercetin, kaempferol and myricetin.
The predominant flavonols are quercitin, kaempferol and isorhamnetin with the flowers containing tenfold more flavonols than fruits and several times more than the leaves.
In another study, volunteers who ate a diet rich in kaempferol were found, on serum and urine analysis, to have improved SOD activity and higher urinary concentration of these polyphenols (35).
The flavonols included seven quercetin derivatives, four myricetin derivatives, seven kaempferol derivatives and two isorhamnetin derivatives.
