Comparison of Matrix Solid-Phase Dispersion and Liquid-Solid Extraction Methods Followed by Solid-Phase Extraction in the Analysis of Selected Furanocoumarins from Pimpinella Roots by HPLC-DAD

The use of matrix solid-phase dispersion (MSPD) was tested to extract some coumarins (umbelliferone, xanthotoxin, isopimpinellin, bergapten, and pimpinellin) from Pimpinella roots. The method was compared with liquid-solid extraction methods (LSE) such as accelerated solvent extraction (ASE), ultrasound-assisted extraction (USAE) and Soxhlet extraction followed by solid-phase extraction (SPE). Several methanol concentrations and temperature conditions were examined during the liquidsolid extraction techniques. The analysis was performed by high-performance liquid chromatography with diode array detector (HPLC-DAD). MSPD extracted furanocoumarins with satisfactory recoveries ranging from 91.65% to 97.55% and relative standard deviations lower than 5,0415%. The results presented in the paper reveal that MSPD is an efficient, fast, simple and easy-to-perform method suitable for the isolation of furanocoumarins from herbs.
