“…The main compounds identified in L. dentata oil were camphor, fenchone and fenchol (61.43, 24.3 and 2.15%, respectively). Tunisian species (Touati et al 2011) showed 1,8-cineole, camphor, and fenchone as major compounds in agreement with the present results. In contrast, main components in Moroccan species were alpha-pinene, beta-pinene, 1,8-cineole and pincarveol (Imelouane et al, 2010), while Algerian species contained 1,8-cineole, beta-pinene, trans-pinocarveol, linalool and myrtenol (Dob et al, 2005;Bousmaha et al, 2006).…”

Mentha longifolia (L.) and Lavandula dentata (L.) (Lamiaceae) are two wild growing folk medicine plants that in Saudi Arabia. This work was conducted to investigate the chemical composition and evaluate the fumigant toxicity of their essential oils against the adults (3-5-day-old) of cowpea beetle, Callosobruchus maculatus (F.) (Coleoptera: Bruchidae). The main compounds in M. longifolia oil were pulegone (74.95%), 1,8-cineole (7.35%), l-menthone (6.62%), and eucarvone (2.68%), while the main constituents in L. dentata oil were camphor (61.43%), fenchone (24.3%), d-fenchol (2.15%), and linalool (1.52%). The two oils showed LC 50 values of 4.43 and 7.92 µl/L air and exhibited antiacetylcholinesterase activity with IC50 values of 1.01 and 9.74 µl/ml, respectively. The results proved the potential use of these natural materials as effective alternatives to synthetic pesticides.

“…Studies regarding the chemical composition of the EO from different species of Lamiaceae indicate that they are composed mainly of monoterpenoids (Hussain et al, 2013;Koc et al, 2013;Moro et al, 2011;Touati et al, 2011;Yousefzadeh et al, 2013). This result is not surprising because the well-known biosynthetic processes of terpenoids in plants are genetically controlled, and species classified in the same family often present major compounds of the same class (Lukas et al, 2013;Najafian, 2014).…”

“…The leaves of H. rhododon presented a yield of 1.0%, whereas the aerial parts of H. marifolia had a yield of 2.0% (Gonzáles-Chávez et al, 2011;Von Poser et al, 1996). In general, species classified in the Lamiaceae stand out by presenting high potential for EO production (Mechergui et al, 2010;Monfared and Ghorbanli, 2010;Ozcan et al, 2011;Raina et al, 2013;Saei-Dehkordi et al, 2010;Touati et al, 2011;Zouari et al, 2011).…”

This study was developed to evaluate the effect of seasonality on the yield and chemical composition of the essential oil (EO) of Hesperozygis ringens (Benth.) Epling, a native species from the Brazilian Pampa. Leaves were collected from four specimens of a single population in each of the four seasons for a year and were extracted in triplicate by hydro-distillation for 2 hours. The yield of EO (% w/w) was calculated on fresh weight basis (FWB), and the 16 oil samples were analyzed by gas chromatography coupled to mass spectrometry (GC-MS) and gas chromatography with flame ionization detector (GC-FID). Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA) were used as statistical tools to evaluate differences in chemical composition. The highest yields were obtained in autumn, spring and summer (2.32-4.38%), while the lowest yields were detected in winter, ranging from 1.15 to 1.91%. Oxygenated monoterpenoids were the predominant class of chemical constituents in the EO obtained in all seasons, showing the highest contents in autumn and summer, and pulegone was identified as a major compound, whose contents varied between 54.13 and 81.17%. The EO samples were divided into three chemical groups by HCA and PCA and were assigned to the same group, except for the three samples gathered in winter. The results showed a seasonal influence on the yield and chemical composition of the EO.Keywords: Lamiaceae, "espanta-pulga", pulegone, oxygenated monoterpenoids. Variabilidade sazonal do óleo essencial deHesperozygis ringens (Benth.) Epling. ResumoEste estudo foi desenvolvido a fim de avaliar o efeito da sazonalidade no rendimento e composição química do óleo essencial (OE) de Hesperozygis ringens (Benth.) Epling., uma espécie nativa do Pampa brasileiro. Folhas foram coletadas de quatro indivíduos de uma mesma população, em cada uma das quatro estações de um ano, e foram extraídas em triplicada por hidrodestilação durante 2 horas. O rendimento do OE (% m/m) foi calculado considerando a base fresca (BF) e as 16 amostras de óleo foram analisadas por cromatografia gasosa acoplada à espectrometria de massas (CG-EM) e cromatografia gasosa com detector de ionização de chamas (CG-DIC). Análise Hierárquica de Cluster (AHC) e Análise de Componentes Principais (ACP) foram utilizadas como ferramentas estatísticas para avaliar as diferenças na composição química. Os maiores rendimentos foram obtidos no outono, primavera e verão (2,32-4,38%), enquanto que os menores foram detectados no inverno, variando de 1,15 até 1,91%. Os monoterpenoides oxigenados foram a classe predominante dos constituintes do OE obtido em todas as estações, apresentando os maiores teores no outono e no verão, e a pulegona foi identificada como o constituinte majoritário, cujos teores variaram entre 54,13 e 81,17%. As amostras de OE foram divididas em três grupos químicos por AHC e ACP e foram classificadas no mesmo grupo, com exceção de três amostras coletadas no inverno. Os resultados demonstraram influência sazonal no rendimento e...

Lavandula pubescens Decne. is one of five Lavandula species growing wild in Yemen. The plant is used in Yemeni traditional medicine, and the essential oil tends to be rich in carvacrol. In this work, L. pubescens was collected from eight different locations in Yemen, the essential oils obtained by hydrodistillation, and the oils analyzed by gas chromatography/mass spectrometry (GC/MS). Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were used to differentiate between the L. pubescens samples. The essential oils were rich in carvacrol (60.9 - 77.5%), with lesser concentrations of carvacrol methyl ether (4.0 - 11.4%), caryophyllene oxide (2.1 - 6.9%), and terpinolene (0.6 - 9.2%). The essential oil compositions in this study showed very high similarity, but it was possible to discern two separate groups based on minor components, in particular the concentrations of terpinolene, carvacrol methyl ether, m-cymen-8-ol, and caryophyllene oxide.
