    Abstract:

    The phenolic acid composition of flowering Caragana frutex shoots was analyzed by the HPLC method. The quantitative content of seven phenolic acids and their derivatives has been determined: gallic, p-hydroxyphenyl acetic, chlorogenic, caffeic, р-coumaric, trans-ferulic, and sinapic) acids. Sinapic acid (513.0 μg/g) and chlorogenic acid (98.4 μg/g) predominate among phenolic acid derivatives. The antioxidant activity of Caragana frutex shoots determined by the ABTS method equaled 9368.51 ± 30.07 μg/g expressed as Trolox equivalent.

    Radical Autoxidation

    2.5K
    The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

    Oxidation of Phenols to Quinones

    3.7K
    In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
    o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...
