Radical Autoxidation01:20

Radical Autoxidation

2.1K
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...

Physical Properties of Alcohols and Phenols

14.3K
Alcohols are organic compounds in which a hydroxy group is attached to a saturated carbon. Phenols are a class of alcohols containing a hydroxy group attached to an aromatic ring. The physical properties of the alcohols and phenols are influenced by hydrogen bonding due to the oxygen–hydrogen dipole in the hydroxy functional group and dispersion forces between alkyl or aryl regions of alcohol and phenol molecules.
Alcohols possess a higher boiling point than aliphatic hydrocarbons of...

Oxidation of Phenols to Quinones01:17

Oxidation of Phenols to Quinones

3.0K
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...

Main Results:

  • Peach kernel oil contains substantial unsaponifiable and phenolic compounds.
  • The n-alkane profile is dominated by tetracosane (n-C24) and tricosane (n-C23).
  • Sweet cap cultivar exhibited high total tocopherol content and superior antioxidant capacity (DPPH and ORAC values).
  • No trypsin inhibitory effect was observed for the tested peach oils.

Conclusions:

  • Peach kernel oil, particularly from the sweet cap variety, is rich in bioactive substances like polyphenols and tocopherols.
  • The oil demonstrates significant antioxidant capacity, making it a promising natural ingredient.
  • Peach oil holds excellent potential for applications in the food and pharmaceutical industries.
