achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...

The essential oil was obtained by hydrodistillation and the identification and quantification of components were achieved with the use of GC-MS analysis. The antioxidant activity was evaluated by the method of sequestration of DPPH. Essential oils were used for study the cytotoxic front larvae of Artemia salina. In the evaluation of the antimicrobial activity of essential oils, we employed the ...

Subterranean termite infestations occur in every state in the contiguous United States and are responsible for damage to wooden structures in excess of two billion dollars (U.S.) annually. Essential oils have historically been used to repel insects. They have relatively low toxicity and some of them are exempt from regulation by the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). Dev...

The aim of the study was to evaluate the antimicrobial activity of essential oils in vitro for possible application to reduce the content of microorganisms in the air of animal houses. The essential oils of Cymbopogon citrarus L. and Malaleuca alternifolia L. were screened against bacteria Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis a...

background: plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. the aim of this study was to evaluate the larvicidal activity of essential oils of three plants of apiaceae family against anophe­les stephensi , the main malaria vector in iran. methods: essential oils from heracleum persicum , foeniculum vulgare and coriandrum sativum seeds were ...

in the present study, we reported the essential oils chemical composition and antibacterial activities of the aerial parts of ajuga chamaecistus ging. ex benth. subsp. scoparia (boiss.) rech.f. thatwere collected duringmay 2013 and april 2014 and extracted by sde (simultaneous distillation–extraction) and clevenger apparatus. gc/ms analysis of the plant essential oils led to the identification ...

the essential oils of peucedanum ruthenicum m. bieb. (umbelliferae) leaves, flowers and fruits were prepared by hydrodistillation and analyzed by gc and gc-ms and the composition of the three essential oils were compared. thirty-three, thirty-seven and thirty-one compounds were identified in leaves, flowers and fruits essential oils representing 89.13%, 88.66% and 76.45% of total oils respectiv...

Nowadays, many antibiotics are being used to control infectious diseases. Inappropriate use of antibiotics leads to emergence of resistant bacteria and problems such as a prolonged course of treatment. Medicinal plants and their derivatives, as a good source of treatment, are effective against drug resistance. In this study we have evaluated the antimicrobial activity of herbal essential oils o...

BACKGROUND To evaluate the antibacterial activity of 21 plant essential oils against six bacterial species. METHODS The selected essential oils were screened against four gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus vulgaris) and two gram-positive bacteria Bacillus subtilis and Staphylococcus aureus at four different concentrations (1:1, 1:5...
