Separation of phenolic compounds from plant materials using supercritical CO2

In the present work supercritical fluid extraction (SFE) using CO2, was applied for the pre-treatment of mandarin peels. Two-step extraction, combining SFE and conventional extraction, was investigated. During the first extraction step supercritical CO2 at temperatures 25, 40 and 60°C and pressures from 100 to 300 bar was applied to remove the non-polar components from the extracting material. ...

Chromatographic separation of glycated nucleotides.

A high-performance liquid chromatographic method for the separation of nucleotide glycation reaction product(s) has been developed. The product(s) arising during in vitro glycation of a nucleotide (AMP, GMP or CMP) with a reducing sugar (ribose or glucose) were clearly resolved from the non-glycated constituents of the reaction mixture. The peak(s) of the glycated product(s) increased when an a...
