). In this context, DMT is extracted using home-made techniques, most notably a variation of the liquid–liquid extraction called “straight to base extraction” (STB). The extract is known to be smoked as obtained in doses of 2–60 mg, producing an

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 liquid—solid 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.
