the hydrodistilled oil of the aerial parts of echiophora platyloba dc. was analyzed by gc and gc/ms. ten components have been identified, of which the major constituents were found to be trans-b -ocimene (67.9%), 2-furanone (6.2%), myrcene (6.0%), linalool (3.1%), and cis-b -ocimene (2.3%).

tagetes is a genus of 56 species of annual and perennial mostly herbaceous plants in the sunflower family (asteraceae or compositae).in this research our goal was recognizing the main components of the plant to extract useful ones. essential oils of the leaves, seeds and flowers of tagets minuta l., growing wild in iran, were extracted by hydrodistillation and analyzed by gc and gc-ms. identifi...

The hydrodistilled essential oils of the leaves and twigs of Litsea mushaensis and L. linii were analyzed. Sixty-nine and ninety compounds were identified in the leaf and twig oils, respectively, of L. mushaensis. The main components of the leaf oil were beta-eudesmol (24.2%), tau-cadinol (10.2%), alpha-humulene (10.1%), alpha-pinene (9.7%), and trans-beta-ocimene (6.5%), whereas the main compo...

Osmanthus fragrans is an ornamental and economically important plant known for its magnificent aroma, and the most important aroma-active compounds in flowers are monoterpenes, mainly β-ocimene, linalool and linalool derivatives. To understand the molecular mechanism of monoterpene production, we analyzed the emission and accumulation patterns of these compounds and the transcript levels of the...

Volatile organic compounds (VOCs) were collected from damaged and intact mulberry leaves (Morus alba L., Moraceae) and from Hyphantria cunea larvae by headspace absorption with Super Q columns. We identified their constituents using gas chromatography-mass spectrometry, and evaluated the responses of male H. cunea antennae to the compounds using gas chromatography-flame ionization detection cou...

The effects of fruit bagging treatments with seven different types bags on the physicochemical characteristics three table grape cultivars: RuiduZaohong (RDZH), RuiduHongyu (RDHY), and RuiduHongmei (RDHM) were investigated. Headspace-solid-phase micro-extraction combined gas chromatography mass spectrometry (HS-SPME-GC-MS) was used to determine compositions monoterpenes in fruit. results showed...

Plants of the family Anacardiaceae have a long history of use by various peoples for medicinal and other purposes. Cotinus coggygria, also known as the “smoke tree”, is one of the two species constituting a small genus of the family Anacardiaceae, viz., C. coggygria Scop. (syn.: Rhus cotinus L.) The Iranian smoke tree, plant material air-dried C. coggygria we...

Dependence of monoterpenoid emission and fractional composition on stomatal conductance (G(V)) was studied in Mediterranean conifer Pinus pinea, which primarily emits limonene and trans-beta-ocimene but also large fractions of oxygenated monoterpenoids linalool and 1,8-cineole. Strong decreases in G(V) attributable to diurnal water stress were accompanied by a significant reduction in total mon...
