Myrtus communis L. young and mature Leaves were collected in Fars (the southern province of Iran). The aim of this research was to investigate essential oil content and composition of myrtle leaves which were at different ontogeny stages. Essential oil was extracted by hydrodistillation method using Clevenger apparatus, the oils were analyzed by GC–MS. Highest content of essential oil were reco...

The essential oil from the leaves of Psidium guajava, collected from Kathmandu, Nepal, was obtained by hydrodistillation and analyzed by GC-MS. A total of 53 compounds were identified, accounting for 100% of the oil composition. The major components of the essential oil were (E)-nerolidol (35.6%) and (E)-caryophyllene (15.8%), with lower concentrations of (2Z,6E)-farnesol (6.7%), and ledol (5.5...

The essential oil (EO) from Salvia sclarea was shown to increase the susceptibility of methicillin resistant Staphylococcus epidermidis (MRSE) isolates to oxacillin. The purpose of this study was to investigate the effect of EO from S. sclarea on expression of mecA gene of MRSE carrying different types of staphylococcal chromosomal cassette (SCCmec) and to evaluate potential synergistic effect ...

Thymus serpyllum L. grown in Kumaon region of Western Himalaya was investigated for essential oil content and composition in different seasons. The oils of fresh samples were obtained by hydrodistillation. The yield of essential oil (% v/w) during different seasons varied from 0.07 to 0.28% with the highest in summer season, at vegetative stage. The oils were analyzed by GC and GC-MS. Major com...

The distribution of J. ashei var. ashei and J. a. var. ovata was examined by leaf essential oils. The populational boundries between these varieties seems to be very distinct. However, there appears to be some intergradation between the two taxa near New Braunfels, Texas.

In this review, several strategies of modification of essential oils by enzymatic treatment are presented. Being either applied before or after the production of the essential oil, enzymatic methods are shown to be particularly adapted to attain the required selectivity, specificity and efficiency in sustainable processes delivering products eligible for the natural grade. Examples dealing with...

The present investigation was carried out at field trail of Main Experimental Station, Vegetable Science N.D.U.A. & T., Kumarganj, Faizabad (U.P.) during 2011-12 to study the performance of turmeric cultivars. Cultivar NDH-7 and NDH-8 was found superior in growth characteristics such as plant height, yield of rhizome/plant. NDH-8 found tallest (111.2 cm) while, yield of rhizome per plant was re...

The aim of this study examined the characterization of extra virgin olive oil samples from the main cultivar Chemlali, grown in five olive orchards with different soil type (Sandy, Clay, Stony, Brown, Limestone and Gypsum). Volatile compounds were studied using headspace-solid phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) technics. Moreover, the sterol profil...

Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at El-Bustan Sandy soil irrigated by drip irrigation, during 2003 and 2004 seasons. The experiments aimed to study the effect of three irrigation treatments with three different kinds of fertilizers and its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content in dry her...
