Preparative Analysis of Catechins
The figure shows the configuration of an LC/MS system for fractionating catechins. This system conducts mass spectrometry on each catechin component and fractionation using the intensity and slope indices of the obtained mass chromatogram. In addition to the high separation performance of HPLC, more reliable fractionation of target compounds can be achieved due to the high selectivity of the mass spectrometer.
The following shows an example of LC/MS fractionation conducted on catechins in green tea. The separation state on the UV detector (SPD-20A) immediately before the fraction collector also allows verification as to whether fraction collection is being performed accurately.
