Characterization of enzymatically synthesized diferulate

Area of Science:

• Biocatalysis and Enzyme Chemistry
• Organic Synthesis
• Spectroscopic Analysis

Background:

• Ferulic acid derivatives are important natural compounds with various biological activities.
• Enzymatic synthesis offers a green and efficient route for producing complex phenolic compounds.
• Understanding the structural and spectral properties of synthesized compounds is crucial for their application.

Purpose of the Study:

• To enzymatically synthesize diferulates using horseradish peroxidase and ethyl ferulate as a substrate.
• To characterize the different forms of synthesized diferulates.
• To investigate the spectroscopic differences between the synthesized diferulates and the starting substrate.

Main Methods:

• Enzymatic synthesis of diferulates using horseradish peroxidase.
• Isolation and purification of four distinct diferulate forms.
• Fluorescence emission and excitation spectroscopy for structural elucidation.

Main Results:

• Four forms of diferulates were successfully synthesized.
• The dominant synthesized forms were identified as 5-5' diferulate and 8-5' diferulate.
• Spectroscopic data revealed the presence of two chromophores in the diferulates, distinct from the ethyl ferulate substrate.

Conclusions:

• Horseradish peroxidase is an effective biocatalyst for synthesizing diferulates from ethyl ferulate.
• The synthesized diferulates exhibit unique spectroscopic properties compared to the substrate.
• This study provides insights into the enzymatic synthesis and characterization of valuable phenolic compounds.
