in the present study the volatile organic compounds of e. azerbaijanica rech.f. were identified. phytochemical assessment of meoh extract of aerial parts of this plant was also performed and its free radical scavenging properties was evaluated. the essential oil of the air-dried aerial parts was obtained by hydro-distillation using a clevenger type apparatus. the oil was then analyzed by gas ch...
In the present study, the chemical composition of the essential oil and methanol (MeOH) extract of aerials of E. azerbaijanica were identified. Furthermore, the free radical scavenging properties of the volatile oil as well as the MeOH extract of the plant were assessed. The essential oil of the air-dried aerial parts was obtained by hydro-distillation using a Clevenger-type apparatus. The oil ...
BACKGROUND Kundmannia anatolica Hub.-Mor. is an endemic specie of Apiaceae diversified in Turkey. Several parts of the plant may contain essential oils in different quantity which can be influenced by environmental factors, mainly altitude. The aim of this study was to test whether there is any altitude effect on volatile chemical constituents of essential oil obtained from the fruits of K. ana...
Purpose: To determine the antimicrobial and antioxidant activities of Pulicaria inuloides and Ocimum forskolei essential oils. Methods: Steam distillation of the aerial parts of P. inuloides and O. forskolei was performed using a Clevenger apparatus. Essential oils were analyzed by gas chromatography–mass spectrometry. Total phenolic content and antioxidant activities were determined by 2,2-dip...
The objective of this study was to determine the chemical composition and antibacterial activity of essential oils (EOs) of Tagetes minuta against three phytopathogenic bacteria Pseudomonas savastanoi pv. phaseolicola, Xanthomonas axonopodis pv. phaseoli, and Xanthomonas axonopodis pv. manihotis. The essential oils were extracted using steam distillation method in a modified Clevenger-type appa...
BACKGROUND To study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of Coccinia grandis against three mosquito species. METHODS Essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (GC-MS). Larvicidal activity was recorded after 12 and 24h...

Fruits of Citrus aurantifolia were subjected to hydro-distillation using Clevenger type apparatus to obtain volatile oil. Chemical composition of volatile oil was analysed by GC–MS. Twenty-two compounds representing...
aqueous extract and volatile oil were obtained from miliusa tomentosa by using soxhlet extractor and hydro distillation with a clevenger-type apparatus respectively. the extract and volatile oil both were screened for antimicrobial activity against different bacteria (escherichia coli, staphylococcus aureus, bacillus subtilis, klebsiella pncumoniae, pseudomonas aeruginosa, bacillus pumilis) and...
The present work reports the phytoconstituents in essential oil and four different solvent extracts of Cinnamomum tamala leaves. Their antibacterial, antifungal, antioxidant potential were also evaluated. extraction was performed by hydro-distillation using Clevenger apparatus its chemical composition identified gas chromatography coupled with mass spectrometry (GC-MS). leaf obtained cold perco...
This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...
