Solvent-free microwave extraction of essential oils from Thymus vulgaris L. and Melissa officinalis L.

New Tricks for Old Guys: Recent Developments in the Chemistry, Biochemistry, Applications and Exploitation of Selected Species from the Lamiaceae Family

“…The antibacterial potential of thyme is well recognized and documented; recently, Cheurfa and Allem [433] tested [434] obtaining excellent results as the extract of this herb had a high antiglycation effect with 50 % inhibitory concentration (IC 50 ) of 0.02 mg/mL. As already stated for essential oils (see previous paragraphs), the use of nanoconstructs can modulate and even ameliorate the bioactivities of vegetable matrices; Proks et al [435] conducted an experiment on four different cancer cell lines: (12), quercetin (30) and phloridzin (54). As regarding uncommon thyme varieties, Khouya and others [436] evaluated the anti-inflammatory, anticoagulant and antioxidant effects of aqueous extracts from Thymus atlanticus, T. satureioides and T. zygis.…”

“…[56] O. vulgare is one of the main species of this genus and then the most studied, however, other minor species show interesting chemical composition associated with biological activities, for example a study of the chemical characterization and the evaluation of antimicrobial, enzyme inhibitory, and antioxidant activities of methanol and water extracts of Turkish O. onites has been recently reported. [424] In total 28 components belonging to polyphenols, flavonoids, terpenoids, organic acids and esters have been identified: 3-O-(4-coumaroyl)quinic acid (16), acacetin (17), cirsimaritin (14), naringenin (9), tuberonic acid glucoside (18), ferulic acid (3), apigenin-7,4'-dimethyl ether (19), azelaic acid (20), baicalin (21), casticin (22), cirsiliol (11), dihydrorobinetin (23), gardenin B (24), genkwanin (25), isoferulic acid (26), kaempferol (27), nevadensin (28), oroxylin A 7-O-glucuronide (29), quercetin (30), rosmarinic acid methyl ester (31), sakuranetin (32) and salvigenin (33).…”

Chemical Composition and Evaluation of Antibacterial Activities of Essential Oil from Lemon (Citrus aurantifolia L.) Leaves Growing Tien Giang Province, Vietnam

“…of biosynthesis constitute essential oils [11][12][13][14][15]. These molecules are different according to the nature of the plant and the ground in which the plant is growing, the period of harvest, the studied part of the plant, the preparation of the sample, as well as the method of extraction [16][17][18][19][20].…”

Profiling of essential oil chemical composition of some Lamiaceae species extracted using conventional and microwave‐assisted hydrodistillation extraction methods via chemometrics tools

“…The extraction of EOs from Mentha spicata L. and Mentha pulegium L. using microwave energy and conventional HD showed microwave as a superior method in terms of selectivity, extraction time, and essential oil composition and as an eco‐friendly method . Saving energy and shorting the extraction time from 240 to 42 minutes were the main advantages of SFME of T vulgaris L. and M officinalis L …”

“…The extraction of EOs from Mentha spicata L. and Mentha pulegium L. using microwave energy and conventional HD showed microwave as a superior method in terms of selectivity, extraction time, and essential oil composition and as an eco-friendly method. 26 Saving energy and shorting the extraction time from 240 to 42 minutes were the main advantages of SFME of T vulgaris L. and M officinalis L. 27 In this study, we investigated the effect of extraction methods (MAHE and HD) on chemical composition of the essential oil of some plants belonging to Lamiaceae family growing in Egypt (O majorana L., Mentha pipereta L., Mentha longifolia L., Origanum syriacum L., Lavandula angustifolia L., Rosmarinus officinalis L., and Thymus vulgaris L.), using gas chromatography-mass spectrometry.…”
