The objective of the current study was to determine the chemical constituents and fumigant toxicity of the essential oil isolated by hydrodistillation form Juniperus foetidissima. The chemical composition of the essential oil was determined by GC and GC-MS. The essential oil included large amounts of monoterpenes 51.4%, with citronellol being the major compound thereof, and sesquiterpines 42.4%...

The biosynthesis of chrysomelidial and plagiodial was studied in the rove beetle subtribe Philonthina (Staphylinidae). Glandular homogenates were found to convert synthetic (2E,6E)-[trideuteromethyl-5,5-(2)H(5)]octa-2,6-diene-1,8-diol (10) into nor-chrysomelidial (14) and nor-plagiodial (13). The overall transformation requires; i) oxidation of the substrate at C(1) and C(8), ii) cyclization of...

Background: Roses have been used since ancient time in rituals, cosmetics, perfumes, medicines and aromatherapy. Turkey, the main rose oil producer in the world, uses R. damascena Mill. for rose oil production. Objective: In this work a comparative survey on chemical composition of essential oils of Rosa damscena Mill. from different locations of Iran has been proposed in industrial scales. ...

The objective of the study was to investigate chemical composition and biological activity Cinnamomum burmannii essential oil in Cao Bang province. Use steam distillation method extract oils. oils determined by Gas chromatography-mass spectrometry (GCMS). Evaluation antioxidant capacity using DPPH free radical method. results this have that has 23 components with main including Citronellal (52....
