Chemical composition, antioxidant, and antimicrobial activities of essential oils from 16 wild edible Tunisian Foeniculum vulgare populations were evaluated. The essential oil yields of fennel seeds ranged from 1.2 to 5.06%. GC-MS analysis revealed the presence of 20 compounds. Except one sample, essential oils from different locations were mainly composed of phenylpropanoid and the major compound was estragole with a percentage ranging from 66.09 to 85%. The phenolic content of fennel oils varied significantly among populations which could explain the high variation in antiradical scavenging activity. Furthermore, essential oils presented antimicrobial activity against several strains. Results showed that the Gram-positive strains of bacteria were most sensitive to fennel oils. This study encourages the use of wild fennel as a potential source of natural antioxidants and antimicrobial agents and supports an assessment of this species in several application domains. Practical applicationsThe growing interest in the use of medicinal plants in food and pharmaceutical industries has led to a systematic examination of plant extracts for their biological properties. Wild fennel is one of aromatic and medicinal plant known for its biological and pharmaceutical activities. In this study, chemical composition, antioxidant, and antimicrobial activities of fennel essential oil were analyzed with a view of their industrial applications. The variations in essential oil composition and their biological activities in different populations may provide baseline data for breeding programs and large scale multiplication for commercial cultivation of the best fennel population.

“…Altitude seems to be an important environmental factor influencing the carvacrol content, where high carvacrol contents were obtained at high altitudes, while chemotypes rich in thymol, α ‐terpineol, and carvacryl methyl oxide were more abundant in areas with low altitudes. Altitude is related to many environmental factors: temperature, precipitations, wind exposure, shortwave solar radiation, air humidity, etc . The increased sunlight incidence and low average temperatures in high altitudes lead plants to change their morphology, physiology, secondary metabolites production, etc .…”

The present study aimed to evaluate the influence of environmental factors on essential oils (EOs) composition of Origanum compactum populations sampled all over the distribution area of the species in Morocco, and to determine the extent of the chemical profiles throughout the geographical distribution of the species. The chemical compositions were submitted to canonical correlation analysis and canonical discriminant analysis that indicated a significant relationship between oil components and some environmental factors. According to their chemical composition and edapho-climatic characteristics, two major groups of populations were differentiated. The first group was composed of samples growing in regions with humid climate, clayey, sandy, and alkaline soils. These samples showed high thymol, α-terpineol, linalool, and carvacryl methyl oxide content. The second group consisted of plants belonging to semi-arid climate, and growing at high altitudes and silty soils. These samples were characterized by high carvacrol, α-thujene, α-terpinene, and myrcene content. However, populations exposed to sub-humid climate, appeared less homogeneous and belong mainly either to the first or second group. A significant correlation between some edaphic factors (pH, K O content, soil texture) and the EOs yield of O. compactum plants was evidenced. In spite of the correlation obtained for the oil composition with edapho-climatic factors and the variance explained by the environmental data set, the observed EO diversity might be also genetically determined.

Resumo: O objetivo deste estudo foi determinar o rendimento e a composição química dos óleos essenciais das folhas secas de quatro acessos de pimenta (Schinus molle L.) coletados em quatro locais diferentes na cidade de Volta Redonda, Rio de Janeiro, Brasil, em quatro estações do ano. Após extração por hidrodestilação e análise química dos óleos essenciais por cromatografia em fase gasosa com detector por ionização em chama (CG-DIC) e cromatografia em fase gasosa acoplada à espectrometria de massa (CG-EM), o biciclogermacreno e o sabineno foram os principais constituintes químicos dos óleos essenciais obtidos durante o verão (34,34 % e 26,54 %), outono (23,63 % e 45,4 %) e primavera (21,06 % e 45,39 %), enquanto mirceno e sabineno foram os principais constituintes encontrados no inverno (21,97 % e 27,32 %), respectivamente. Observou-se que o perfil metabólico de Schinus molle tem forte influência da sazonalidade, uma vez que este foi variável ao longo do ano. Palavras-chave: Sazonalidade; aroeira; monoterpeno; sesquiterpeno. AbstractThe objective of this study was to determine the yield and chemical composition of the essential oils of the dry leaves of four accessions of false pepper tree (Schinus molle L.) collected at four different sites in the city of Volta Redonda, Rio de Janeiro, Brazil, in four seasons of the year. After hydrodistillation extraction and chemical analysis of the essential oils by GC-FID and GC-MS, bicyclogermacrene and sabinene were found to be the major chemicals in the essential oils obtained during the summer (34.34 % and 26.54 %), autumn (23.63 % and 45.4 %) and spring (21.06 % and 45.39 %), while myrcene and sabinene were the main chemicals found during winter (21.97 % and 27.32 %) respectively. It was observed that the metabolic profile of Schinus molle has strong influence of seasonality, since this was variable throughout the year.
