Abstract:
An effective method based on the combined homogenate-assisted high-pressure disruption extraction (HHPDE) was applied to the extraction and determination of the main phenolic acid compounds from Lonicerae Japonicae Flos. The optimized HHPDE showed competitive advantage in yield (The extraction yields of NCA, CA, 3,5DCA and 4,5DCA in HHPDE were 1.21, 1.08, 1.06 and 1.17 fold higher than those in UAE), time-saving (<5 min) and relative low temperature requirement (4-16 °C) compared to HRE and UAE. Furthermore, the HHPDE method behaved a good repeatability and reproducibility according to the HPLC. The mentioned HHPDE method is firstly applied in the extraction and quantification of neochlorogenic acid chlorogenic acid, 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid in Lonicerae Japonicae Flos. This work provided an excellent alternative for the extraction and quantification of thermosensitive from plants.

Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:
Oxidation of Phenols to Quinones
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...
Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and...
