Abstract

Intermolecular copigmentation of malvidin-3--glucoside with caffeine was studied using a holistic procedure that includes the extension to basic pH values. In moderately basic solutions (7.5 < pH < 9.5) and independently of the copigment presence, there is a pH region where degradation of the quinoidal base and anionic quinoidal bases is faster than hydration and OH nucleophilic addition, preventing the system from reaching the equilibrium. Intermolecular copigmentation with caffeine reduces significantly the degradation rate of quinoidal bases. In a more basic medium, the equilibrium is reached and degradation occurs from the anionic chalcones. In this case, the addition of caffeine also reduces the degradation rate in the interval 10 < pH < 11.5.

摘要

使用包括扩展到碱性pH值的整体程序，研究了矢车菊素 - 3 - 葡萄糖苷与咖啡因的分子间共色素沉着。在适度碱性溶液（7.5 < pH < 9.5）中，且与共色素的存在无关，存在一个pH区域，其中醌式碱和阴离子醌式碱的降解速度比水合作用和OH亲核加成更快，从而阻止系统达到平衡。与咖啡因的分子间共色素沉着显著降低了醌式碱的降解速率。在更碱性的介质中，达到平衡且从阴离子查耳酮发生降解。在这种情况下，添加咖啡因也会降低10 < pH < 11.5区间内的降解速率。
