摘要:Quercetin,The Polyphenolic Compound,Which Has The Highest Daily Intake,Is Well Known For Its Protective Effects Against Aging Diseases And Has Received A Lot Of Attention For This Reason. Both Quercetin 3-O-Beta-D-Glucuronide And Quercetin 3'-O-Beta-D-Glucuronide Are Human Metabolites,Which,Together With Their Regioisomers,Are Required For Biological As Well As Physical Chemistry Studies. We Present Here A Novel Synthetic Route Based On The Sequential And Selective Protections Of The Hydroxyl Functions Of Quercetin Allowing Selective Glycosylation,Followed By Tempo-Mediated Oxidation To The Glucuronide. This Methodology Enabled Us To Synthesize The Five O-Beta-D-Glucosides And Four O-Beta-D-Glucuronides Of Quercetin,Including The Major Human Metabolite,Quercetin 3-O-Beta-D-Glucuronide.

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.
