1H NMR spectroscopic analysis of aromatic protons combined with theoretical analysis of molecular structures proved the existence of two rotational isomers at 300 K, as well as a rapid interconversion equilibrium at 330 K for both compounds Ⅰ and Ⅱ. However, only one conformer exists for compound Ⅲ and puerarin containing 7-phenolic hydroxyl instead of propyl in A-ring as the case of compounds Ⅰ and Ⅱ. Based on UV-Visible absorption data of neutral and basic solutions, and on the density function calculations, the 7-phenolic hydroxyl group in A-ring was found to be more acidic than the 4'-phenolic hydroxyl group in B-ring. The mechanism of derivation reaction and the structure-reactivity relationship of puerarin as an antioxidant were further discussed.
其中7-丙基葛根素Ⅱ属于新型取代衍生物;变温1H NMR和理论计算结果表明,在300 K时,葛根素和4'-丙基葛根素以单一构型存在;而7,4'-二丙基葛根素和7-丙基葛根素则存在两种核磁可分辨的旋转异构体,当温度升至330 K时,两种异构体可以相互转化;通过对比分析葛根素及其衍生物脱质子产物的紫外可见吸收光谱并结合理论计算,确定了A环上7位酚羟基比B环上4'位酚羟基先脱去质子,并由此进一步阐明了葛根素衍生化反应机理以及在抗氧化作用中可能的活性位点和结构活性关系。

PMN has a function of oxidation and adsorption under acidic conditions, such as Gentian Purple, Methylene Blue, Conga Red, Rhodamine B and Methyl Orange. PMN can oxidize diversiform dyes (pH<4. 5). The increasing of concentration on Mn and wastewater UV-Vis spectra after contact can prove it.

But, because of the complexity of the dye molecule, there has been short of detailed comprehension in its photocatalytic degradation process. The key problem is difficult to detect the intermediates clearly. In this paper, the photocatalytic degradation of azo dye Congo red in water solution was investigated on UV irradiating TiO2 in the homemade reactor. The optimization conditions were determined and then the rate of decolorization, COD decrease, yield of CO2 and varies pH of aqueous solution during illumination were detected; The varies of the possible intermediates during degradation process were monitored with UV-VIS spectrum and HPLC. The possible mechanism of Congo red photocatalytic degradation is discussed combined with the data of MS.

This is due to the fact that AFP in the sample flows through the sample pad and binds the conjugate to form a complex. This complex then migrates down to the membrane and binds to the immobilized anti-AFP antibody A2 of the test line, resulting in the immobilization of the reddish conjugate.
