Comparison of pennyroyal oils obtained by supercritical CO2 extraction and hydrodistillation
Flavour and Fragrance Journal, 1999Flowers and leaves of pennyroyal (Mentha pulegium L.) were extracted using supercritical CO2 followed by a two-stage fractional separation technique. Using a flow apparatus with an extraction vessel (1 l) and two separators (0.27 l), the best conditions of extraction (P=100 bar and T=50°C) and of separation (P=80 bar, T=−16°C for the first separator ...

Isolation of (R)-(+)-Pulegone from the European Pennyroyal Mint, Mentha Pulegium
The Chemical Educator, 2002Students obtain, via steam distillation, pennyroyal essential oil that is analyzed by capillary gas chromatography—mass spectrometry. TLC experiments establish conditions for preparative scale purification of the major oil component via flash column chromatography. The terpene obtained, (R)-(+)-pulegone, is characterized spectroscopically, employing at
