“…Lemos et al [20] found the same principal components in the essential oil from R. officinalis, but in very different quantities. The authors found a higher percentage of camphor (24.38%), followed by 1,8-cineole (19.74%) and α-pinene (15.18%).…”

Essential oils from Mentha piperita, Cymbopogon citratus, Rosmarinus officinalis, Peumus boldus and Foeniculum vulgare were extracted by hydrodistillation, chemically characterized and quantified by GC/MS and GC/FID. The principal componentes in the essential oil of M. piperita (carvone and limonene), C. citratus (geranial, neral and myrcene), R. officinalis (1,8-cineole, camphor and α-pinene), P. boldus (α-terpinyl formate, p-cymene and 1,8-cineole) and F. vulgare (methyl chavicol, limonene and fenchone) were identified. The oils were tested for antioxidant activity employing the DPPH (2,2-diphenyl-1-picryl-hydrazyl) radical-capture method, the oxidation of the β-carotene/linoleic acid system, and the ABTS radical-capture method. The essential oils were not effective. The antioxidant activities of the oils were determined by the hydroxyl method, and the highest activity (62.80%) was observed with the essential oil from M. piperita. Activities of 1.54 and 1.82 μg μg −1 , respectively, were observed for the essential oils from C. citratus and P. Boldus using the phosphomolybdenum method. No activity was observed with respect to reducing power. The essential oil from C. citratus was effective in inhibiting the growth of L. monocytogenes ( How to cite this paper: Rezende,

“…[161] The seasonal variation showed significant effects in the composition of the essential oils of R. officinalis with a greater amount of the oil and the main components in the summer. [162] Very interesting is a recent work evaluating the effect of diurnal variations on chemical composition and biological activities of S. officinalis EOs. [163] What is interesting in the discussion on the correct interpretation and assignment of chemotypes is that the results of this study indicate that the EO of plants harvested at 7 am and 12 pm were of α-thujone chemotype while those collected at 5 pm were of camphor chemotype with an important impact on biological activities.…”

Lamiaceae is one of the largest families of flowering plants comprising about 250 genera and over 7,000 species. Most of the plants of this family are aromatic and therefore important source of essential oils. Lamiaceae are widely used as culinary herbs and reported as medicinal plants in several folk traditions. In the Mediterranean area oregano, sage, rosemary, thyme and lavender stand out for geographical diffusion and variety of uses. The aim of this review is to provide recent data dealing with the phytochemical and pharmacological studies, and the more recent applications of the essential oils and the non‐volatile phytocomplexes. This literature survey suggests how the deeper understanding of biomolecular processes in the health and food sectors as per as pest control bioremediation of cultural heritage, or interaction with human microbiome, fields, leads to the rediscovery and new potential applications of well‐known plants.

“…7,15 The antioxidant activity of the EO of Rosemary was linked to its main components 16 which vary with seasonal variations. 17 Besides its antioxidant potential, the extracts of Rosemary have been studied before for their antidiabetic effect. 8 However, very few studies reported the antidiabetic effect of Rosemary EO.…”

“…22 Such variations in composition and subsequently on biological effect caused by seasonality should be screened in order to obtain an EO with standard quality. 17 This study was conducted in order to assure the quality and safety of herbal products before being available to the public, pharmacognostic screening on Rosmarinus officinalis and Lavandula angustifolia (Linn.) grown in Lebanon was conducted.…”

Introduction:The world health organization recommends validating medicinal plants to ensure safety and efficacy. Lavandula is valued for the production of essential oil used in aromatherapy. Rosmarinus is known for its folk use as anti-oxidant and antidiabetic. This study aims to design monographs for Rosmarinus officinalis (Linn.) and Lavandula angustifolia (Linn.) cultivated, in conditions similar to their natural habitat, at Beirut Arab University botanical garden. Also screening the antioxidant activity of both plants, and assessing the antidiabetic effect of R. officinalis (Linn.). Methods: macroscopic and microscopic examination, hydrodistillation to obtain essential oils (EOs), thin layer chromatography, Gas chromatography-Mass spectrometry, and physiochemical properties of the EOs were determined. The antioxidant effect of the EOs is determined by DPPH assay. The antidiabetic effect of Rosemary EO is investigated using alloxan-induced diabetic mice. Results: the qualities of studied species are in agreement with the standards described in WHO monographs and in the British pharmacopeia. Composition of the EO produced from either Rosemary (REO) or Lavender (LEO) collected at different months showed differences. The EO of both showed significant antioxidant effects in DPPH assay (p<0.05). In vivo investigation of the antidiabetic effect of REO showed a significant antidiabetic effect in diabetic mouse model (p<0.05). Conclusion: both plant species and their EOs fulfilled most of standards specified by the British Pharmacopeia 2013. Rosemary collected in April (Spring) showed the best antioxidant activity. Lavender collected in September (Early Fall) showed the best antioxidant activity. REO revealed significant lowering in blood glucose level at the dose of 110 mg/kg.
