In the course of the evaluation of the species belonging to the Section Salvia of the genus Salvia (Family Lamiaceae) the essential oil content and the composition of the species have been investigated with special respect to their neurotoxic α-, and β-thujone content. It could be established that from among the species S. lavandulifolia Vahl., S. candelabru Boiss., S. tomentosa Mill., (S. gran...

Thujone is thought to be the main constituent of medicinal herbs that have antidiabetic properties. Therefore, we examined whether thujone ameliorated palmitate-induced insulin resistance in skeletal muscle. Soleus muscles were incubated for < or =12 h without or with palmitate (2 mM). Thujone (0.01 mg/ml), in the presence of palmitate, was provided in the last 6 h of incubation. Palmitate oxid...

the essential oils of the aerial parts of a. armeniaca and a. incana , collected from arasbaran area (east azarbaijan province, iran) were extracted by hydrodistillation and analyzed by gc-ms. in total, 16 and 40 constituents were identified and quantified in the oils of a. armeniaca and a. incana representing 80.5% and 84.6% of the oils, respectively. the essential oil of a. armeniaca was main...

Background: Fritillaria imperialis is an endangered species with pharmaceutical alkaloids that can be effective in reducing blood pressure and reducing cardiac palpitations.   Objective: Comparison of head space solid phase microextraction (HS-SPME) and hydro-distillation (HD) techniques in determination of essential oils in Fritillaria imperialis Methods: Quality and quantity determination o...

the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...

thegenus achillea is one of the most important medicinal plants in the asteraceae family. nineteen species of this genus have been described in the flora iranica, of which achillea aucheri boiss is an endemic species to iran. given the effect of geographic location on the quality and yield of essential oil, we performed an investigation to determine oil contents of a. aucheri growing at differe...
