The chemical composition and antibacterial activity of Thymus glabrescens Willd. (Lamiaceae) essential oil were examined, as well as the association between it and chloramphenicol. The antibacterial activities of geraniol and thymol, the main constituents of T. glabrescens oil, individually and in combination with chloramphenicol, were also determined. The interactions of the essential oil, ger...

The components of the essential oil from the roots of Alangium salviifolium were analyzed by capillary gas chromatography-mass spectrometry (GC-MS). Ninety compounds, representing 74.5% of the total oil, were identified; the main components of the oil were epi-α-cadinol, followed by trans-2-hydroxycalamenene, cadalene, and cadina-4,10(15)-dien-3-one. A further unknown component comprised 5.5% o...

The chemical compounds present in the essential oil obtained from the flowers of Leea indica (Burm. f.) Merr. were analyzed by GC-MS technique. More than 95% of the oil consisted of the esters of phthalic acid. Di-isobutylphthalate (>75%), di-n-butylphthalate (>7%), n-butylisobutylphthalate (>6%), butylisohexylphthalate (>3.5%) were identified as major constituents of the essential oil. Monobut...

background: mentha longifolia is one of the aromatic medicinal plant belongs to lamiaceae family. there are some active ingredients in the essential oil of m. longifolia, which potentially could impair the hepatic function. the aim of this study was to find the maximum dose of essential oil of m. longifolia (eoml) that does not show any hepatic deterioration. methods: adult wistar rats fed diff...

A new chemical compound is developed at Petroleum University of Technology to enhance the recovery of the free imbibition process and simultaneously hinder asphaltene precipitation. The compound is tested on heavy oil samples from Marun oil field, Bangestan reservoir. The effects of the chemical compound on viscosity, hydrocarbon composition, and average molecular weight of the heavy oil are in...

Umbellularia californica (California bay laurel) and Laurus nobilis (Mediterranean bay laurel) leaves may be mistaken or used as a substitute on the market due to their morphological similarity. In this study, a comparison of anatomical and chemical features and biological activity of both plants is presented. L. nobilis essential oil biting deterrent and larvicidal activity were negligible. On...

In a screening program for new agrochemicals from Chinese medicinal herbs and wild plants, essential oil of Homalomena occulta (Lour.) Schott rhizome was found to possess strong nematicidal activity against the root-knot nematodes, Meloidogyne incognita (Kofoid and White) Chitwood. The essential oil of H. occulta rhizome was extracted via hydrodistillation and investigated by gas chromatography...

background trachyspermum ammi or carum copticum, commonly known as ajowan or ajwain is a plant used as a spice. thymol, the major phenolic compound present in ajowan is known as a strong germicide and anti-spasmodic. it is also used for cleaning the wounds and treating skin infections. objectives here, we aimed to study the inhibitory effects of ajowan essential oil on microorganisms like esche...
