[Fluid chromatography in supercritical conditions: a method potentially useful for flavonolignan analysis]

The behaviour of high polar polyphenolic compounds (taxifolin and the flavolignans of the silymarin complex) by supercritical fluid chromatography (SFC), using standard HPLC packed columns (0.46 cm i.d.) and CO2 as the primary mobile phase, was studied. The elution and separation of the flavonolignans by some of the systems investigated was shown.
