The composition of the hydrodistilled essential oils from the fruits and leaves of Thuja orientalis L. grown in Iran was analyzed by GC/MS. Nineteen and twenty-eight compounds have been identified in the volatile oils of the fruit and leaf, respectively. While the fruit oil contained alpha-pinene (52.4%), delta-3-carene (14.2%), alpha-cedrol (6.5%) and beta-phellandrene (5.1%), the leaf oil con...

Nepal’s unique geographical features, frequent political disturbances, strikes, a limited and complicated road network, frequent road breakdowns, government interventions as well as a volatile international oil market make the supply chain of Nepal Oil Corporation (NOC) rather unique. We analyze different risks in the NOC supply chain and discuss what can be done to find inventory strategies th...

The composition of the steam-distilled volatile oil of fresh and air-dried, indoor-grown marijuana was studied by GC/FID and GC/MS. In all, 68 components were detected of which 57 were fully identified. Drying of the plant material had no effect on the qualitative composition of the oil and did not affect the ability of individuals familiar with marijuana smell to recognize the odor.

The essential oil of Salvia aegyptiaca was analysed by GC/ MS technique. Eighteen compounds were identified. It was found that the essential oil comprises 40% terpenoidal constituents, opposite to 32% fat derivatives. The major terpenoidal component was 1(10)aristolene (19.3%). From the non-volatile matter, β-amyrin, lupeol, β-sitosterol, stigmasterol, β-sitosterol-β-D-glucopyranoside and stigm...

The volatile oil from the stem bark of Scutia buxifolia (Rhamnaceae) has been obtained by hydrodistillation and analyzed by GC-MS. Twenty-one components were identified representing 99.93 % of the total oil composition, spathulenol (35.87%), β-cubebene (17.26%), germacrene D (6.43%), linalool (5.19%), carvacrol (4.05%) were the main components of S. buxifolia essential oil. Antioxidant and anti...

Tulsi (Ocimum sanctum Linn.) herb has been known from as early as the Vedic period. Its extract has numerous pharmacological activities like hypoglycaemic, immunomodulatory, antistress, analgesic, antipyretic, anti-inflammatory, anti-ulcerogenic, antihypertensive, CNS depressant, radioprotective, antitumour and antibacterial. The active constituents of the herb include volatile oil chiefly euge...

The present study identified volatile flavor components of Hanwoo longissimus muscle and other Korean foods (Doenjang, Chungukjang, sesame oil) and their traits were compared in relation with flavor precursors that include fatty acids and protein degradation products. Hanwoo longissimus muscle was purchased from a commercial abattoir while the other foods were sampled from three separate househ...

AIMS We investigated the antimicrobial effectiveness of lemongrass essential oil on organic leafy greens, romaine and iceberg lettuces and mature and baby spinach, inoculated with Salmonella Newport. The influences of exposure times and abuse temperatures on bacterial survival were also investigated. METHODS AND RESULTS Leaf samples were washed, inoculated with Salm. Newport (6-log CFUml(-1) ...

Dear Sir, We read the excellent short review article of Higgins et al. (1) on contact allergy to and the safety of eucalyptus oil with great interest. Having recently finished writing a full literature review of contact allergy to and the chemical composition of essential oils (2), we would like to give some additional information on eucalyptus oil. Also, we will address the question raised by ...

The quality of olive oil is influenced by genetic and environmental factors and by the maturation state of drupes, but it is equally affected by technological treatments of the process. This work investigates the possible correlation between olive LOX gene transcript accumulation, evaluated in fruits collected at different stages of maturation, and chemical biomarkers of its activity. During ol...
