Purpose: Suitable ratio of essential fatty acids has an important role in maintaining good health. There is no pure oil with an ideal fatty acid composition and oxidative stability. The main goal of the present study was to evaluate the physical, chemical and nutritional properties of oil obtained by blending flaxseed oil as a rich source of ω3 fatty acids with sesame and olive oils. Methods: T...
Purpose: To determine larvicidal activity of the essential oil derived from Illicium henryi Diels (Illiciaceae) leaf and stem against the larvae of Aedes albopictus Skuse. Methods: The essential oil of I. henryi leaves was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromaotography-mass spectrometry (GC-MS). The activity of the oil was evaluated, using World He...

Chemical composition of the essential oil obtained from the aerial parts of Scrophularia amplexicaulis Benth. was analyzed, for the first time, by the gas chromatography/mass spectrometry (GC-MS) and gas chromatography/flame ionization detection (GC-FID). A total yield of 3 mg of essential oil per100 g of plant dry mass was obtained, and 27 compounds were identified, representing 97.7% of total...
Background: Lemon verbena (Lippia citriodora H.B.K.) is an aromatic and medicinal plant of family Verbenaceae, which cultivated in the North region of Iran. Objective: This comparative study was carried out on essential oil content and composition of Lippia citriodora H.B.K. from micro-propagated and rooted apical stem cutting plantlets. Methods: The micro-propagated plantlets were obtained ...
The medicinal shrub, scientifically named Myrtus communis L. is one of the valuable wild medicinal shrubs. The aim of this study was to investigate the essential oil, phenol and flavonoid compositions of this plant in three forest habitats of Zagros. For this purpose, leaf samples were prepared from 20 stands with a distance of at least 15 meters during the flowering season. Then, essential oil...
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...
Effective antibacterial and antioxidant properties of methanolic extract of Laurus nobilis seed oil.
This study was carried out to determine the in vitro antimicrobial and antioxidant activities of the essential oil, seed oil, and methanolic extract of seed oil obtained from Laurus nobilis L. (Lauraceae). The methanolic extract of seed oil exhibited more effective antibacterial activity comparing to essential oil and seed oil, GC-MS analyses of the essential oil resulted in the identification ...
