This study was carried out to evaluate the effects of phenological and diurnal variation on volatile oil content quality Salvia officinalis L. (Lamiaceae) cultivated in Afyonkarahisar/Turkey. The harvesting times based ontogeny were pre-flowering, flowering post-flowering stages. took place three a day, at 6:00 a.m., 2:00 8:00 p.m. results showed that highest obtained stage (2.05%). In general,...

The high cost of chemical pesticides and their negative impact on the environment prompted search for natural from plants. objective our study was to control rice seed pathogenic fungi bacteria using aqueous extract essential oil Tithonia diversifolia leaves. We obtained oil, respectively, by maceration hydrodistillation; antimicrobial activities were determined in vitro a solid medium food poi...

Chios Mastic Gum (CMG) and Oil (CMO) are two unique products of the tree Pistacia lentiscus var. Chia, cultivated exclusively on Greek island Chios. In present study, method proposed by European Pharmacopoeia for mastic identification was employed using HPTLC together with an in-house method. A GC-MS methodology also developed chemical characterization CMOs. α-Pinene β-myrcene were found in abu...

Abstract Eucalyptus essential oils are used as traditional medicines in many countries. The objective of this study was to evaluate the antioxidant and anti-inflammatory activities leaf extracted from three different species on HepG2 RAW264.7 cells. Essential were distilled fresh samples, chemical constituents analyzed using gas chromatography–mass spectrometry. determined ABTS hydroxyl radical...

Plectranthus is a large and widespread genus with a diversity of ethnobotanical uses. In traditional medicine P. mollis has been used against snakebites, respiratory stimulant and vasoconstrictor, cardiac depressant, cure for haemorrahage, treatment of mental retardation and rheumatism. P. mollis is reported to exhibit relaxant activity on smooth and skeletal muscles, and has cytotoxic and anti...

The phytotoxicity of the three major monoterpene constituents of the essential oil from leaves of Artemisia scoparia Waldst. & Kit. (redstem wormwood) was investigated. GC/GC-MS analysis revealed that the essential oil (yield 0.84%) is a complex mixture containing 19 monoterpenes, 7 sesquiterpenes and 15 other compounds--aliphatic alcohols, ketones, aromatic hydrocarbons and esters. The three m...

Five monoterpenes naturally occurring in essential oils were tested for their insecticidal and repellent activities against the bruchid beetle Callosobruchus maculatus and the maize weevil Sitophilus zeamais. The monoterpenes were highly efficient as inducers of mortality or repellency against both insect species. They were more efficient in their fumigant activity against C. maculatus than aga...

Many monoterpenes have been identified in forest emissions using gas chromatography (GC). Until now, it has been impossible to determine whether all monoterpenes are appropriately measured using GC techniques. We used a proton transfer reaction mass spectrometer (PTR-MS) coupled with the eddy covariance (EC) technique to measure mixing ratios and fluxes of total monoterpenes above a ponderosa p...
