In the present investigation, essential oil (EO) and methanolic extract of Tunisian Mentha spicata leaves were tested for their chemical composition and biological activities. Results showed that EO was characterized by the predominance of oxygenated monoterpenes (92.18%), followed by monoterpene hydrocarbons and sesquiterpenes whose respective amounts were 2.74 and 3.1% of the whole EO. The main volatile compound of M. spicata EO was L‐menthone, accounting for 32.74% of the total volatiles, followed by pulegone (26.67%). The phenolic composition of methanolic extracts was determined by reversed‐phase high‐performance liquid chromatography. The major flavonoid component was apigenin with a mean concentration of 38.4 mg/100 g dry weight. M. spicata leave extract tested for their antioxidant and antibacterial activities showed a significant antiradical and superoxide anion scavenging capacity in addition to the great potential for antimicrobial activities against the bacteria tested. PRACTICAL APPLICATIONS Spearmint (Mentha spicata L.) is an aromatic plant belonging to the Lamiaceae family. M. spicata L. is commercially cultivated in many regions of the world. Spearmint oil has economical importance and is used in perfumery, confectionary and pharmaceutical preparations. Tunisia is blessed with a rich source of aromatic plants, many of which have not been previously investigated for their chemical constituents and biological potentials. Among these plants, we can mention M. spicata L. (Lamiaceae), which is largely distributed from the humid to the upper arid regions. This work was carried out as a first step for a chemical and biological activity of Tunisian M. spicata through phenolic and essential oil composition. A further isolation and purification of M. spicata phenolics and volatiles will be associated with an application in food industry as antioxidants, additives for food preservation and for enhancing their nutritional value and organoleptic quality. Furthermore, a pharmacological study could be established through in vivo assays in order to discover new anticarcenogenic, anti‐inflammatory, antimutagenic and other activities of M. spicata. Such results could be used in pharmaceutical formulations, leading to new human drugs from this medicinal plant.

“…In fact, a composition dominated by 2-undecanone was found in the essential oil of R. chalepensis from Turkey (66.0 %), Iran (52.0 %) and India (41 to 68.0 %) 27,28,29 , however, extracted essential oil from this plant in Italy showed that 2-undecanone and 2-nonanone were major compounds 32 . Previous reports have attributed the chemo-variation of essential oils among varieties to genetic and environment factors 31,32,33,34,35 . The chemical composition of R. chalepensis oil determines the chemotaxonomy of the plant.…”

To our knowledge, this study is the first to investigate the biological activities of the methanolic extracts of leaves, roots and stems of Ruta chalepensis L. (Rutaceae) in Tunisia. The chemical composition of the essential oil extracted from R. chalepensis leaves was determined by GC-MS. The antioxidant activities of tested essential oil and the methanolic extracts of leaves, stems and roots of R. chalepensis were evaluated using DPPH and ABTS radicals scavenging tests. Their antimicrobial activities were achieved by disc diffusion method and broth dilution assay. The main components of the selected essential oil were menthol (43.92 %) and linalool (42.10 %). Significant differences were found between the total phenol contents and biological activities of the different parts of R. chalepensis. In addition, significant correlations were observed between antioxidant activities and phenolic contents for methanol extracts. In fact, leaves extract presented higher total phenol content than stems and roots extracts. The tested oil showed better antioxidant activity than methanolic extracts. The highest antioxidant activity was recorded in leaves methanolic extract. The latter showed strong antibacterial activity against tested microorganisms, whereas the evaluated oil remained almost inactive. The inhibition zones diameters and minimal inhibitrice concentration values for tested bacteria, which were sensible to different methanolic extracts, were in the range of 8-35 mm and 0.78-25 mg/ml, respectively. This study demonstrated that the R. chalepensis extract can be regarded as promising candidate for natural plant source of antioxidant and antimicrobial agents.

“…In other crop plants such as wheat the levels of antioxidant enzymes (superoxide dismutase, glutathione reductase, peroxidase) and the antioxidants ascorbic acid and glutathione increase to combat reactive oxygen species 13. However, there is little information regarding the effects of heat stress on members of the mint family 14. The growing conditions could have implications on the metabolic activity for spearmints earmarked as a source of high‐quality rosmarinic acid and other phenolic antioxidants for commercial use.…”
