AN357: Extraction of Phenolic Acids from Plant Tissue Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

This application note will focus on the extraction of phenolic acids from two different plants (eggplants and black cohosh) using ASE. The ASE results from five different eggplant samples are compared to eight different extraction techniques. Data from the extraction of black cohosh show the results of the optimum ASE conditions for this matrix, focusing on temperature and solvent choice.

Improved analysis of catechins and phenolic acids in red wine using Thermo Scientific HyperSep Retain SPE and a Thermo Scientific Accucore PFP HPLC column

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the determination of catechins and phenolic acids in red wine. The samples are prepared using Thermo Scientific HyperSep Retain PEP solid phase extraction (SPE) cartridges, and the separation performed on a Thermo Scientific Accucore PFP HPLC column.
