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...

Acute Oral Toxicity and Brine Shrimp Lethality of Methanol Extract of Mentha Spicata L (Lamiaceae)

Purpose: To determine, in Sprague Dawley rats, the toxicity profile of the methanol extract of Mentha spicata, a plant used in folklore medicine for the treatment of various forms of pain. Methods: The plant extract, at concentrations ranging from 100 0.07 mg/ml, was used to determine the median lethal concentration (LC50) based on brine shrimp lethality assay. Artificial sea water served as co...

Phenolic and Volatile Composition of a Dry Spearmint (Mentha spicata L.) Extract.

The present paper reports a complete mass spectrometric characterization of both the phenolic and volatile fractions of a dried spearmint extract. Phenolic compounds were analysed by ultra-high performance liquid chromatography-electrospray ionization-mass spectrometry (UHPLC-ESI-MS(n)) and a total of 66 compounds were tentatively identified, being the widest phenolic characterisation of spearm...
