Aims: This study aimed to the extraction of Melaleuca cajuputi essential oils by microwave-assisted method. The comparison for productivity method and traditional hydro-distillation was also established figure out optimum condition isolation process.
 Methodology: Microwave-assisted employed oils. components contained in were analyzed gas chromatography-mass spectrometry. Standard methods ...
Chemical composition and phytotoxicity of essential oils of Croton doctoris S. Moore (Euphorbiaceae)
Abstract Essential oils from the stems and leaves of Croton doctoris were analyzed by gas chromatography mass spectrometry, resulting in 22 identified compounds. The effects these essential on germination, root shoot growth, total chlorophyll content, potential respiration, peroxidase activity, catalase, superoxide dismutase, mitotic index lettuce onion determined. Antioxidant, antimicrobial, c...
The essential oils of Piper cernuum and Piper regnellii leaves were analyzed by gas chromatography-mass spectrometry (GC-MS) and the results were compared to that obtained by means of a program designed to analyse (13)C-NMR data of complex mixtures. Bicyclogermacrene (21.88 %)/beta-caryophyllene (20.69 %) and myrcene (52.60 %)/linalool (15.89 %) were the major constituents in essential oil from...
Hexane, chloroform, ethyl acetate and ethanolic extracts of the aerial parts of Centaurea austro-anatolica Hub.-Mor. (Asteraceae) were evaluated against microorganisms, including multiresistant bacteria, using a paper disc diffusion method. The chloroform extract exhibited significant antibacterial activity toward all bacteria tested. The chemical composition of the chloroform extract was deter...
Carrot seed oil is the source of the carotane sesquiterpenes carotol, daucol and beta-caryophyllene. These sesquiterpenic allelochemicals were evaluated against Alternaria alternata isolated from the surface of carrot seeds cultivar Perfekcja, a variety widely distributed in horticultural practise in Poland. Alternaria alternata is one of the most popular phytotoxic fungi infesting the carrot p...
The essential oils of water-distilled aerial parts of Anthemis pseudocotula and Anthemis cretica subsp. pontica (Asteraceae) were analysed by GC-MS. As a result thirty-five and forty compounds were identified representing 93.1% and 89.0% of the oils, respectively. The main compounds of A. pseudocotula were 1,8-cineole (39.40%), camphor (9.36%), artemisiaketone (5.68%), filifolene (5.15%), and a...
background: the genus lagochilus, family lamiaceae consists of 44 species, 33 of which grow in central asia. only one report on the analysis of essential oil of lagochilus species has been published. objective: aim of this study is to determine the chemical composition and antimicrobial activities of the hydrodistilled oil of flower and leaves of lagochilus kotschyanus boiss. of iranian origin ...
The pathogenesis of nonalcoholic steatohepatitis (NASH) is not fully understood, but many studies have suggested that oxidative stress plays a key role. The methionine- and choline-deficient diet (MCD) administration model can reproduce histopathological features of human NASH and is widely used for investigating NASH. C57BL/6J mice have been used in many studies, but strain differences in path...
Phytochemical analysis of the leaf extract Zanthoxylum caribaeum Lam (Family Rutaceae) collected in La Garita district, Municipality Los Patios Norte de Santander, Colombia, is reported. Ethanolic extracts by simple maceration were concentrated at reduced pressure. Secondary metabolites found preliminary identification demonstrated presence alkaloids, tannins, carotenoids, anthocyanins, coumari...
