研究了氯化马柳素（马柳素3,5-二葡糖苷）与水合马柳素（3,5,7,2′4′-五羟基黄酮）的共色素化过程。利用紫外-可见吸收光谱确定了合成色素的最佳条件及其特性。我们确定了共色素化过程不仅取决于羟基的数量，还取决于它们的相互位置。共色素的形成在光谱上表现为最长波长吸收带的深色和深色移位。形成的色素由动力学和热力学参数定义。
The process of copigmentation between malvin chloride (malvidin 3,5-diglucoside) and morin hydrate (3,5,7,2'4'-pentahydroxyflavone) was studied. The UV-vis absorption spectra were used to define the optimum conditions for the formation of copigment, as well as their characteristics. Et was established that the copigmentation process does not depend only on the number of hydroxy groups but also on their mutual position. The copigment formation is spectrally manifested in a bathochromic and hyperchromic shift of the longest wavelength absorption band. The copigment formed is defined by kinetic and thermodynamic parameters.
