An overview of the studies carried out in our laboratories on supercritical fluid extraction (SFE) of volatile oils from seven aromatic plants: pennyroyal (Mentha pulegium L.), fennel seeds (Foeniculum vulgare Mill.), coriander (Coriandrum sativum L.), savory (Satureja fruticosa Béguinot), winter savory (Satureja montana L.), cotton lavender (Santolina chamaecyparisus) and thyme (Thymus vulgari...
The cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Bruchidae), is an important pest of stored cowpea, Vigna ungiculata (L.) Walpers (Fabales: Fabaceae), with ample distribution in tropical and subtropical regions. Many plant essential oils have a broad-spectrum activity against pest insects, and these oils traditionally have been used in the protection of stored products. In this study...
Synthetic chemicals are used to protect crops and agricultural products, thereby producing high yields. However, intensive use of these synthetic significantly affects the environment sustainable agriculture production. Moreover, direct or indirect exposure may cause acute chronic toxicity in humans animals. Due their biodegradability, low toxicity, being environmentally friendly, secondary met...
essential oil extracted from the leaves of lemon verbena, lippia citriodora kunth (verbenaceae) was tested for fumigant toxicity in the laboratory against two stored-product insects tribolium confusum jacquelin du val and callosobruchus maculatus (f.). the chemical composition of the isolated oil was examined by gc-ms. the major compounds were citral (11.3%), limonene (10.6%), neral (7.9%), 4-p...
the potato tuber moth (ptm), phthorimaea operculella zeller (lepidoptera: gelechiidae), is an important pest of potato and other solanaceous plants. it is cosmopolite and oligophage that exists in most countries where potatoes are grown. because of chemical treatment adverse effects, there is a necessity to find safe alternatives to synthetic insecticides. so, medicinal plants are promising sin...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
plant tissue culture techniques are used as basic requirement of common plant transformation systems. in most cases of plant transformation, a reproducible regeneration protocol is the limiting step due to long time lasting, specialized facilities and well experienced persons. furthermore, tissue culture procedures induce somaclonal variation among regenerated transgenic plants. therefore, rece...
