kelussia odoratissima mozaff. is an iranian endangered endemic edible plant with enormous use in the middle region of iran as food and spice especially yogurt seasoning, and as medicinal herb as anti-inflammatory and cardiovascular purposes. although antioxidant, anti-inflammatory and hypolipidemic effects of this plant have so far been studied, but chemical analyses of the non volatile constit...

In the title compound, C(15)H(26)O(3)·H(2)O, a sesquiterpenoid mol-ecule with a germacrene backbone that contains two epoxide groups and one hydroxyl group. Inter-molecular O-H⋯O hydrogen bonds between the ep-oxy groups and solvent water mol-ecules give rise to an infinite three-dimensional supra-molecular structure.

This study investigates the impact of seasonal variation on the chemical composition of essential oils from the leaves of Porcelia macrocarpa (Annonaceae) obtained over the course of one year (January-December 2011) and the chemical composition of the essential oils obtained from the ripe fruits of the same plant. Furthermore, the essential oils of the leaves were investigated with respect to t...

Aroma compounds in Cascade and Chinook hops harvested from multiple Virginia locations were identified by gas chromatography-mass spectrometry-olfactometry (GC-MS-O) aroma extract dilution analysis (AEDA). Selected quantitated combination of stable isotope (SIDA) standard addition method (SAM). A total 33 aroma-active detected five samples with β-myrcene, methyl octanoate, geraniol linalool bei...

The volatile oil content and composition of the aerial parts of Ajuga orientalis L. (Lamiaceae) grown in northern parts of Iran have been analyzed by GC/MS. Thirty compounds were identified, representing 97.9% of the total oil. The main compounds were germacrene-D (24.2%), beta-cubebene (18.3%), beta-caryophyllene (16.9%) and alpha-cubebene (5.3%).

The hydro-distilled essential oil from dried aerial parts of one of widespread Iranian skullcaps, Scutellaria pinnatifida A. Hamilt. sap. alpina (Bornm.) Rech. grown in Khorassan province was analyzed by GC and GC/MS. Thirty components were characterized ing 93.8% of the total components detected. The major components of the oil were germacrene-D (39.7%) and beta-caryophyllene (15.0%).

The objective of this study was to investigate the seasonal variance content and chemical composition essential oil from Lantana camaraaccessions at two harvest times, analyze trypanocidal activity on Phytomonas serpens. Essential ranged 0.13 0.29% in rainy season 0.33% dryseason. compounds E-caryophyllene, α-humulene, α-curcumene germacrene D defined formation four clusters dry seasons, classi...

Lutzomyia longipalpis, a sibling complex, is the main vector of Leishmania chagasi/infantum. Discriminating between siblings is important as they may differ in vectorial capacity. Lutzomyia longipalpis populations display distinct male sex pheromone chemotypes. We investigated the phylogeographic pattern of variation at microsatellite loci from 11 populations from Brazil and Venezuela related t...

In this study, the essential oil (EO) constituents from the aerial parts of Satureja intermedia C.A.Mey were detected by GC and GC/MS. The antimicrobial activity of EO on oral pathogens and its cytotoxicity to human cancer cells were determined by the microbroth dilution method and the crystal violet staining method, respectively. Thirty-nine compounds were identified and the main EO constituen...
