Kaempferol is a polyphenol antioxidant found in fruits and vegetables. Many studies have described the beneficial effects of dietary kaempferol in reducing the risk of chronic diseases, especially cancer. Epidemiological studies have shown an inverse relationship between kaempferol intake and cancer. Kaempferol may help by augmenting the body’s antioxidant defense against free radicals, which promote the development of cancer. At the molecular level, kaempferol has been reported to modulate a number of key elements in cellular signal transduction pathways linked to apoptosis, angiogenesis, inflammation, and metastasis. Significantly, kaempferol inhibits cancer cell growth and angiognesis and induces cancer cell apoptosis, but on the other hand, kaempferol appears to preserve normal cell viability, in some cases exerting a protective effect. The aim of this review is to synthesize information concerning the extraction of kaempferol, as well as to provide insights into the molecular basis of its potential chemo-preventative activities, with an emphasis on its ability to control intracellular signaling cascades that regulate the aforementioned processes. Chemoprevention using nanotechnology to improve the bioavailability of kaempferol is also discussed.

“…Tea ( Camellia sinensis (L.) O. Kuntze, Theaceae) has been widely consumed as a beverage and used in traditional Asian medicines for centuries. Since the cancer‐protective effect of drinking green tea was reported,1, 2 numerous studies have focused on the isolation and biological effect of each component contained in tea, especially the polyphenols 3, 4. Anti‐cancer effects,5, 6 anti‐aging effects,4 cholesterol‐lowering effect,7 and potential health benefits8 of tea have been reviewed in the literature.…”
