The Chemical compositions and the Antioxidant and Antimicrobial Activities of the Essential Oil of Rosemary Leaves from Eastern Morocco

The essential oils compositions of Rosmarinus. tournefortii wild plant, Rosmarinus. tournefortii domesticated plant, and Rosmarinus officinalis.L wild plant growing in different bio climates from eastern Morocco, was determined by GC-FID and GC–MS. Oils were assessed for their antimicrobial and antioxidant activities. A variation of chemical compositions attributed to varieties rather than to bio climates was revealed. α-Pinene (0.637% ; 44.22% ; 5.74%), Camphene (11.62% ; 6.52% ; 2.21%), ß-Pinene (14.72% ; 1.14% ; 3.71%), 1,8-Cineole (10.1% ; not identifying ; 56.51%) and Camphor (39.27% ; 7.64% ; 13.56%) were identified as the main constituents of R. tournefortii wild plant, R. tournefortii domesticated plant, and R. officinalis. L wild plant respectively. This study is based on the determination of the diameter of inhibition to moderate antimicrobial and antioxidant activities of oils revealed to be against eight bacteria tested. This was determined by 1,1-diphenyl-1-picrylhydrazyl (DPPH) assay. The highest antimicrobial and antioxidant activities were found in oils from Rosmarinus. tournefortii domesticated plant

Chemical composition and antioxidant activity of essentiel oil, various organic extracts of Cistus ladanifer and Cistus libanotis growing in Eastern Morocco

peer reviewedIn the present work, we studied the chemical composition of the essential oil of Cistus ladanifer and Cistus libanotis growing in Eastern Morocco. Camphene, borneol, cyclohexanol-2, 2, 6 tremethyl, terpineol-4 and α-pinene were the main constituents of the essential oil of C. ladanifer, while in the essential oil of C. libanotis we obtained terpineol-4, γ-terpinene, camphene, sabinene, α-terpinene and α-pinene. The result show that C. ladanifer of the leaves of methanol: water (50:50) extract had the highest value of total phenolic content and the lowest was present in ethanol: water (50:50) extract of the stem and acetonitrile extract of the flowers of C. libanotis. From our experimental results, the extract of flowers, fruit, stem and leaves of those plants showed highest potential as free radical scavenger

Chemical Composition of the Essential Oil of Pistacia lentiscus L. from Eastern Morocco

peer reviewedThe essential oil from leaves of Pistacia lentiscus L., an aromatic member of the Anarcadiaceae family from Eastern Morocco, obtained by hydrodistillation, was analysed by GC-FID and GC-MS. The constituents were identified by their mass spectra and Kovats’indices. About 104 constituents were detected in the oil. From these components, about 40 could be identified and quantified, comprising over 88.6% of the oil. The main constituents of the oil were: myrcene (39.2%), limonene (10,3) -gurjunene (7.8), germacrene (4.3%), -pinene (2.9%), muurolene (2.9), -humulene (2.6), Epi- bicyclosesquiphellandrene (2.5), -pinene (2.2). The results of this study shows both qualitative and quantitative differences with oils from P. lentiscus L of other countries
