Supercritical CO2 extraction of mentha (Mentha piperita L.) at different solvent densities

The chemical composition of mentha essential oil and mentha extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC–MS. The menthol content was also determined spectrophotometrically. The predominant compounds in the essential oil and in the CO2 extract obtained at 100 bar were L-menthon and menthole but at higher pressures (from 150 to 4...

Environmental Factors Affecting the Accumulation of Rosmarinic Acid in Spearmint (Mentha spicata L.) and Peppermint (Mentha piperita L.)

Four spearmint, and two peppermint clonal lines, selected for enhanced rosmarinic acid content (50-120 mg g -1 rosmarinic acid DW), where up to 80% of the antioxidant activity was correlated to rosmarinic acid content, were examined to determine the effects of environmental and physiological conditions on the accumulation of rosmarinic acid in leaf tissues. Exposure to a short photoperiod of 12...
