Aims: The cultivation of medicinal plants in intercropping with other species of agricultural use has been an alternative to make production sustainable in family farming. The objective of this work was to evaluate the growth, biomass production, and chemical composition of the essential oil of mint (Mentha x gracilis Sole) in intercropping with fruit species in an agroforestry system. This study was conducted as an important contribution to agroforestry management practices and to assist in deciding which intercropping option to use in this cultivation system. In particular, this information should facilitate the establishment of scientific intercropping systems, help maintain the sustainable use of agroforestry and provide a theoretical basis for the sustainable development of agriculture. Study Design: The experimental design was randomized blocks with four treatments, mint inter planted with citrus (Citrus sinensis L. Osbeck), bananas (Musa spp.), blackberries (Morus nigra), or Ba...

Objective of study was to find out a beneficially recycling of the thinned and chopped woods massively produced in mountainous regions Japan. Essential oil extraction was one of the effective approaches to overcome its issues. Materials from Crytomeric japonia, Lindera umbellata, Thujopsis dolabrata and Anise magnolia chips was applied for oil extraction by steam distillation and was chemically analyzed by Gas Chromatography. Preclinical studies of the essential oil were done with a support of the elderly commuting to the Day Care Service Center. Test room was created with the forest pictures, bird singing and water flowing sound as back ground music. Essential oil-flavored test was done to know the elderly preference using the questionnaire test. The most favorite flavor by the elderly was Lindera umbellata due to make them refreshing. But they selected Thujopsis dolabrata flavor instead of Lindera umbellata, when changing the napkin. It implies that “Different flavor for Different ...

Essential oil chemical constituents of Jatropha curcas were analyzed for the effect of lead (Pb) on in vitro shoots. A total of 36 and 30 compounds obtained from in vitro and Pb treated shoots. The four compounds were α-copaene, β-bourbonene, T-muurolol and lauric acid increased parentage in Pb treated in vitro shoots. Lead treated in vitro shoots resulted in production of 21 new compounds and increased percentage of fatty acid, alkanes and aldehyde.

Annona senegalensis Pers., Oulotricha Le Thomas subspecies (Annonaceae), is an evergreen shrub that is used for ethnomedicinal purposes and as a source of food. The chemical composition of the essential oils from leaves, stems bark, roots bark, epicarp and mesocarp of these plant, growing in Brazzaville (Congo), were analyzed by CG and CG-MS. These oils essentially contain sesquiterpenic compounds (58.3-97.7%), dominated by oxygenated sesquiterpenes (21.8-88.3%), with elemol (13.2-35.0%), β-and γ-eudesmols (3.7-58.3%) as characteristic components. The essential oils from roots and stems bark is distinguished by its high content in diterpenes (17.1 and 11.9% of the total), while the seeds presents a significant amounts of monoterpene hydrocarbons (25.8%) with α-pinene (6.2%) and β-phellandrene (11.5%) as major components accompanied by two oxygenated monoterpenes : bornyle acetate (4.5%) and smallest of 1,8-cineole. However, in the epicarp oil, the presence of about 5.8% of oxygenated...

Background: Malaria remains a serious Public Health threat in the sub-Saharan regions. Although Anopheles gambiae (main malaria vector) has developed resistance against commonly used insecticides, the emergence of this resistance as well as the pollution of the environment by these chemicals have led to the use of plant-derived products such as essential oils. Aim: This study aimed to characterize and investigate in laboratory bioassays the ovicidal, larvicidal and pupicidal activities of Ocimum basilicum essential oil against aquatic stages of Anopheles gambiae, the main malaria vector in Cameroon. Methods: Essential oils of O. basilicum fresh leaves were extracted by hydro-distillation, characterized by gas chromatography coupling mass spectrometry (GC-MS) and tested against An. gambiae eggs, larvae and pupal stages in laboratory bioassays. Results: With an overall yield of 0.31% (w/w), the essential oil of O. basilicum fresh leaves revealed the presence of 29 compound...
