AbstractIn this study, microwave assisted a hydrodistillation process (MWHD) of essential oils from lavender (Lavandula angustifolia Miller) was investigated. In order to examine any potential differences in essential oil extraction, the lavender flowers underwent enzymatic pretreatment.A 23 factorial design of experiments, combined with statistical methods of data analysis were used to optimize enzymatic pretreatment and to evaluate the influence of major variables (enzyme concentration, temperature and pH) on the performance of the microwave assisted extraction.Under optimal conditions, an extraction yield of 24 mg oil g−1 substrate was achieved (an increase by approximately 25% in comparison with the classic extraction conditions of conventional hydrodistillation).The main compounds of the essential oils obtained were analyzed and identified by gas chromatography coupled to mass spectrometry (GC-MS). Analyzing the data obtained indicated that the content of main compounds (linalool and linalyl acetate − 73%) was greater than that obtained by conventional extraction (67%).

Origanum Compactum

In this work, we aimed at determining some nutrients from Origanum compactum (OC) and comparing its essential oils (OCEOs) isolated using microwave-assisted extraction (MW) and Clevenger hydrodistillation (HD). To this end, dried flowering tops from OC were subjected to nutrients screening, OCEOs were isolated separately using MW and HD and then analyzed using GC-MS. Our results showed that OC contained important amounts of moisture (58.66%), minerals (10.26%), mainly K (6.22), Ca (2.62), Mg (2.09mg/gDM), Fe (0.998), Mn (0.085 mg/gDM), proteins (5.65%DM), chlorophyll a (1.09) and b (0.20 mg/gDM), and several amino acids. Among them, two (Ile and Leu) were essential. MW showed its superiority in terms of OCEO yield (7.41%), total compounds (95.57%), and almost individual compounds. These results were confirmed by the principal component analysis, which discriminated clearly MW and HD through the first component. In both techniques, thymol and carvacrol were the major constituents accounting for 78.81 ± 0.22 and 14.84 ± 0.39%, respectively, in the case of MW against 75.07 ± 0.99 and 13.03 ± 0.30% for HD. Following our outcomes, OCEO was a thymol chemotype, and OC contained important amounts of nutrients. MW could serve as a green, efficient method over HD for OCEO isolation.
