Water-distilled essential oil from the aerial parts of Dipsacus japonicus Miq. (Dipsacaceae) at the flowering stage was analysed by gas chromatography-mass spectrometry (GC-MS). Forty-six compounds, accounting for 96.76% of the total oil, were identified and the main compounds of the essential oil were linalool (11.78%), trans-geraniol (8.58%), 1,8-cineole (7.91%), beta-caryophyllene (5.58%), a...

objectives: the objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of ligularia persica boiss (l. persica) growing wild in north of iran. materials and methods: essential oils were extracted by using clevenger-type apparatus. antibacterial activity was tested on two gram-positive and two gra...

Drug resistance in the treatment of neglected parasitic diseases, such as leishmaniasis and trypanosomiasis, has led to the search and development of alternative drugs from plant origins. In this context, the essential oil extracted by hydro-distillation from Lantana camara leaves was tested against Leishmania braziliensis and Trypanosoma cruzi. The results demonstrated that L. camara essential...

The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of Illicium pachyphyllum fruits against two grain storage insects, Sitophilus zeamais and Tribolium castaneum, and to isolate any insecticidal constituents from the essential oil. The essential oil of I. pachyphyllum fruits was obtained by hydrodistillation and analyzed by GC-MS. A tota...

Dracocephalum moldavica L. is an annual species of Lamiacea family whose essential oil is widely used in medicinal, food, cosmetic and health industries. Drought stress is a major factor limiting plants growth and yield. The main objective of this study was to evaluate the influence of irrigation regime on essential oil content and composition of D. moldavica L. The Irrigation regimes were 100%...

The objective of this study was to investigate the chemical composition and in vitro antifungal activity Mentha × Piperita L. (peppermint) essential oil (EO) against some plant pathogenic fungi (Alternaria alternata, Penicillium expansum, Rhizoctonia solani, Rhizopus stolonifer). Antifungal EO selected conducted using agar diffusion method by adding peppermint concentrations (0, 250, 500, 750, ...

The objective of the current study was to determine the chemical constituents and fumigant toxicity of the essential oil isolated by hydrodistillation form Juniperus foetidissima. The chemical composition of the essential oil was determined by GC and GC-MS. The essential oil included large amounts of monoterpenes 51.4%, with citronellol being the major compound thereof, and sesquiterpines 42.4%...

Backgroud:Lippia alba (Verbenaceae) is a plant widely used in folk medicine to treat various diseases. The present work deals with the chemical composition of the crude essential oil extracted from leaves of L. alba and evaluation of its antimicrobial and cytotoxic activities. Methods: Leaves of L. alba were extracted by hydrodistillation and analyzed by gas chromatography/mass spectrometry (GC...

The essential oils were obtained by hydro-distillation from the roots and rhizomes of two umbelliferous species Ligusticum sinense and L. jeholense. They were analyzed for their chemical composition by GC and GC-MS. 5-Oxo-δ-4-decahydrobenzindene (50.1%), ligustilide (16.4%), β-phellandrene (7.8%), myristicine (5.5%), and spathulenol (3.3%) were the major compounds of the 25 identified component...
