The chemical composition of the Hydrolate of Citrus aurantium L. (Rutaceae) flowers (neroli) grown in Iran, and two commercial hydrolates were analyzed by GC/MS. Thirty compounds (90.3%) were identified in the Hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the Hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

Using GC-MS and GC-flame ionization detection (FID)/olfactometry, 95 volatile components were detected in orange essence oil, of which 55 were aroma active. In terms of FID peak area the most abundant compounds were: limonene, 94.5%; myrcene, 1%; valencene, 0.8%; linalool, 0.7%, and octanal, decanal, and ethyl butyrate, 0.3% each. One hundred percent of the aroma activity was generated by sligh...

Zinc oxide is a well established sensor material for detection of various organic molecules. In a quest of developing a sensor array for quality assessment of black tea, we have attempted developing pure and doped nanocrystalline zinc oxide pellet based sensors. The materials are sintered at 3500C and 5000C separately for six and three hours respectively. We obtained a highly reproducible senso...

The aim of the study was comparing the chemical composition of the essential oils from five varieties of lavender (Lavandula angustifolia L.), and its biological activity against two pathogenic bacteria, Staphylococcus aureus and Pseudomonas aeruginosa. In the comparison we included the following varieties: 'Munstead', 'Munstead Strain', 'Lavender Lady', 'Ellegance Purple' and 'Blue River'. Sel...

Lactic acid bacteria, such as Lactococcus lactis, are attractive hosts for the production of plant-bioactive compounds because of their food grade status, efficient expression, and metabolic engineering tools. Two genes from strawberry (Fragaria x ananassa), encoding an alcohol acyltransferase (SAAT) and a linalool/nerolidol synthase (FaNES), were cloned in L. lactis and actively expressed usin...

Benzene is a volatile chemical implicated in leukemia and hepatic injury through oxidative stress-mediated mechanism. Linalool naturally small molecular monoterpene with proven antioxidant pro...
