The composition of the essential oil from ripe and unripe berries and leaves of Juniperus oxycedrus L. ssp. oxycedrus, Juniperus phoenicea ssp. turbinata and Juniperus communis ssp. communis was analyzed by GC-MS, and microbiological assays were carried out. Samples were collected in different localities (Sardinia, Italy) and hydro distilled. The yields ranged between 2.54% +/- 0.21 (v\w dried ...

The present study aimed to investigate the in vitro mutagenic activity of Origanum majorana essential oil. The most abundant compounds identified by GC-MS were γ-terpinene (25.73%), α-terpinene (17.35%), terpinen-4-ol (17.24%), and sabinene (10.8%). Mutagenicity was evaluated by the Salmonella/microsome test using the preincubation procedure on TA98, TA97a, TA100, TA102, and TA1535 Salmonella t...

Essential oils produced by plants, and their components, could be sources of new natural herbicidal compounds. Thirteen extracted from six wild Lamiaceae species (namely Clinopodium suaveolens (Sm.) Kuntze, Satureja montana L. subsp. montana, Thymbra capitata (L.) Cav., Salvia fruticosa Mill. thomasii (Lacaita) Brullo, Guglielmo, Pavone & Terrasi, cuneifolia Ten., Thymus spinulosus Ten.) So...

Higher production of secondary metabolites is one the adaptive responses to alleviate impact environmental injuries. In present investigation, these with medicinal importance induced by salinity in Carum copticum was investigated. To develop a better way for substances, callogenesis and plant regeneration were analyzed, seeds, calli, and/or regenerated seedlings exposed different concentrations...

Aphids are destructive pests, and alarm pheromones play a key role in their chemical ecology. Here, we conducted detailed analysis of terpenoids the vetch aphid, Megoura viciae, its host plant Pisum sativum using gas chromatography/mass spectrometry. Four major components, (-)-?-pinene (49.74%), (E)-?-farnesene (32.64%), (-)-?-pinene (9.42%) ( +)-limonene (5.24%), along with trace amounts +)-sa...

Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...

The morphological and essential oil diversity of Stachys lavandulifolia populations from the west northwest Iran were evaluated. results showed a significant difference between for nearly all evaluated traits. broadest variation ranges recorded auxiliary shoot length, leaf length in main branch, number flowers inflorescences. Furthermore, cluster analysis divided 13 into four separate groups. G...

Objective. To evaluate the synergistic analgesic effect of essential oil of Zanthoxylum schinifolium Sieb. et Zucc. (EOZ) and verapamil (Ver). Method. The qualitative and quantitative composition of EOZ were determined with gas chromatography/Mass spectrometer. The interaction between EOZ and Ver in antinociceptive activity was evaluated by using acetic acid-induced writhing, hot plate, and tai...

--We investigated the hypotheses that two different varieties of Arabidopsis thaliana show differences in physiology and terpene production. The two varieties of A. thaliana used in this study were wild-type (WT) and transgenic line (CoxIV-FaNES I) genetically modified to emit nerolidol with linalool/nerolidol synthase (COX). Photosynthetic rate, electron transport rate, fluorescence, leaf vola...
