专利号:US-2007232495-A1 优先权日:2006-03-24 标题:Compositions and methods to add value to plant products, increasing the commercial quality, resistance to external factors and polyphenol content thereof 发明人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 权利人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.
参考标题:Regioselective Synthesis Of 6-Alkyl- And 6-Prenylpolyhydroxyisoflavones And 6-Alkylcoumaronochromone Derivatives 作者:Masao Tsukayama,Hironari Wada,Yasuhiko Kawamura,Kazuyo Yamashita,Masaki Nishiuchi 摘要:The Palladium-Catalyzed Coupling Reaction Of 6-Iodoisoflavone, Prepared From 3′-Iodoacetophenone Derivative, With 2-Methyl-3-Butyn-2-Ol Gave 6-Alkynylisoflavone Derivative, Which Was Hydrogenated To Give 6-Alkylhydroxyisoflavone (Luteone Hydrate) (2). Dehydration Of 2 Gave 2′,4′,5,7-Tetrahydroxy-6-Prenylisoflavone (Luteone) (1). Wighteone Hydrate (3) Was Also Synthesized From 6-Iodotris(Benzyloxy)Isoflavone In A Similar Manner. 6-Alkyl-4′5,7-Trihydroxy-Coumaronochromone (4) Was Synthesized By Oxidative Cyclization Of 2 With O-Chloranil.
