Several studies involving the family Verbenaceae, occurring in the Brazilian Cerrado, have emphasized the popular use of many aromatic species. We highlight the use of Lippia sidoides Cham., known as "alecrim pimenta," native to northeastern Brazil and northern Minas Gerais. Leaves of this species were collected in antropized Brazilian Cerrado area, in Hidrolândia, Goiás, and their essential oi...

The volatile aroma constituents of Chrysanthemum zawadskii var. latilobum K. were separated by hydro distillation extraction (HDE) method using a Clevenger-type apparatus, and analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of C. zawadskii var. latilobum K. flower essential oil (FEO) was 0.12% (w/w) and the color was light green. Fifty-five volatile chemical components, whic...

The objectives of this study were to chemically characterize and evaluate the antioxidant activity of essential oils Cinnamodendron dinisii Schwacke (pepper) and Siparuna guianensis Aublet (negramina). The essential oil was isolated by hydrodistillation using a Clevenger modified apparatus, and the identification and quantification of constituents, through GC/MS and GC-FID analysis. The antioxi...

This research analyzed both engineering and nontechnical issues involved in the use of Induction Loop Amplification (ILA) devices in auditoriums or large gathering places for hard-of-hearing individuals. A variety of parameters need to be taken into account to determine an optimal shape/configuration for the ILA device. In many cases, an optimal configuration is different from those proposed fo...

This study investigated the chemical composition, and antimicrobial activity against food-borne pathogens of essential oil isolated from heartwood Calocedrus formosana Taiwan. The oil, by hydrodistillation in a Clevenger-type apparatus, was characterized using GC–FID GC–MS. major constituents were τ-muurolol (16.1%), α-cadinol (11.1%), α-terpineol (10.6%), thymol (8.5%), β-thujaplicin (4.5%). d...

The aim of this work was to study the chemical composition and antioxidant activity essential oils Thymus ciliatus (Desf.) Benth from middle Algeria obtained aerial parts by hydrodistillation using a Clevenger-type apparatus. oil analyzed gas chromatography (GC) coupled with mass spectrometry (GC-MS). capacity values T extracts were determined 2 different complementary assays: free radical scav...

This article has focused on essential oils as alternative fuels and fuel additives. The oil is obtained from Salvia Candidissima plant. While a Clevenger type apparatus was used to determine the yield of plant, retort produced for bulk be in experiments. compounds were determined by Gas chromatography / Mass spectrometry (GC MS) converted into biofuel. biofuel added 5% volume reference diesel (...
