The new rich source of rotundifolone:<i>Mentha aquatica</i>Linn. var.<i>crispa</i>oil from microwave-assisted hydrodistillation

Since herbal medicines play an important role in the treatment of a wide range of diseases, there is a growing need for their quality control and standardization. Mentha suaveolens Ehrh. (MS) is an aromatic herb with fruit and a spearmint flavor, used in the Mediterranean areas as a traditional medicine. It has an extensive range of biological activities, including cytotoxic, antimicrobial, antioxidant, anti-inflammatory, hypotensive and insecticidal properties, among others. This study aims to review the scientific findings and research reported to date on MS that prove many of the remarkable various biological actions, effects and some uses of this species as a source of bioactive natural compounds. On the other hand, piperitenone oxide (PO), the major chemical constituent of the carvone pathway MS essential oil, has been reported to exhibit numerous bioactivities in cells and animals. Thus, this integrated overview also surveys and interprets the present knowledge of chemistry and analysis of this oxygenated monoterpene, as well as its beneficial bioactivities. Areas for future research are suggested.

“…The extraction method used in the present study was useful for evaluating the insecticidal properties of C. macrostemum. This is because the microwave-assisted extraction method is a more efficient method for this purpose because it enables the enhancement of several of the extracted essential oil properties, including toxicity, antimicrobial and larvicidal activities, in comparison to that obtained by conventional techniques 10,[22][23][24] . The major compounds identified in the present study and larvicidal activity against the mosquito species have been found in other Lamiaceae species and therefore represent a defense and attack system for Cx.…”

Introduction:In the present study, we determined the chemical composition of Clinopodium macrostemum essential oil obtained by microwave-assisted hydrodistillation and its effect on the growth and development of Culex quinquefasciatus mosquito larvae. Methods: The essential oil compounds were identified by gas chromatography-mass spectrometry analysis, and bioassays were conducted to evaluate the influence on the developmental stages of early second instar larvae of Cx. quinquefasciatus until the emergence of adults, using essential oil concentrations of 50, 100, 200, 400, and 800mg/L. Results: The gas chromatographymass spectrometry analyses revealed that the leaf essential oil of C. macrostemum contained 32 compounds and the major chemical compounds identified were linalool (55.4%), nerol (6.4%), caryophyllene (6.25%), menthone (5.8%), geraniol acetate (4.1%), terpineol (3.7%), and pulegone (2.8%). The essential oil yield obtained by microwave-assisted hydrodistillation was 0.8% at 20 min. The treatments showed lethal concentrations (LC50 and LC90) of 22.49 and 833.35mg/L, respectively, after the final measurement of the total number of dead larvae (second, third, and fourth instars), and LC50 and LC90 of 6.62 and 693.35mg/L, respectively, at the end of the experimental period. The essential oil inhibited the growth and development of the mosquito larvae by 32% (relative growth index = 0.68) at 50mg/L, and up to 47% (relative growth index = 0.53) at 800mg/L. Conclusion:The present study demonstrated the larvicidal effect of C. macrostemum essential oil on Cx. quinquefasciatus, which can be attributed to the oxygenate compounds obtained by the extraction method.

“…Practically, the combination of hydrodistillation and microwave-assisted extraction (MAHD) has been successfully utilized to separate essential oils from different parts of the plants [9][10][11][12][13] . However, these laborious procedures often require large amounts of samples and are also are timeconsuming.…”

The present study describes the potential capabilities of four different extraction techniques, namely hydrodistillation (HD), solvent-free microwave extraction (SFME), microwave assisted hydrodistillation (MWHD) and headspace solid-phase microextraction (HS-SPME) to isolate the essential oils and volatile fractions from the aerial parts of Ferula ovina in combination with analysis by GC and GC-MS. By means of the HD, SFME, MWHD and HS-SPME methods, 14, 30, 20 and 28 components were identified in the chemical profiles, representing 100 %, 95.6 %, 97.4 and 98.2 % of the total compositions, respectively. It was observed that in all of the profiles, monoterpene hydrocarbons constituted the main components while the next most common are oxygenated monoterpenes. In addition, the class order of natural compounds through the HD, SFME and MAHD approaches are the same whereas a slightly difference pattern is observed when using HS-SPME.
