chemical composition of the essential oil of the fruit of ferula assafoetida l. obtained by steam distillation solvent extraction methodhas been studied by gc/ms for the first time. fifty-four components, comprising 96.9% of the total oil, were identified.epi-α-cadinol (23.15 %), germacrene b (10.98 %), α-gurjunene (6.18 %), (z)-1-propenyl secbutyl disulfide (5.89 %), 5-epi-7-epi-α-eudesmol (4....

The essential oils obtained from different officinal plants of Lebanon, belonging to the Magnoliophyta division, have been tested for their antiproliferative activity on human erythroleukemic K562 cells. Satureja montana showed the most interesting biological activity in inhibiting the cell growth and inducing erythroid differentiation of K562 cells. The essential oil of Satureja montana was th...

Multiple positive effects that forests have on human health and overall well-being been reported widely in the literature. Still, multiple elements of this relationship remain unidentified unexplained. In study, composition leaf volatile organic compounds (BVOCs) content three common coniferous species: Austrian pine (Pinus nigra), Scots sylvestris) Spruce (Picea abies), was analyzed. The speci...

Abstract The essential oil (EO) composition of leaves Campomanesia aurea was analyzed by GC-MS. plant collected in April (EOA) and October (EOO) São Francisco de Assis/RS. oils were obtained hydrodistillation a modified Clevenger apparatus. yields 4.44% April, 6.15%, October. Thirty-one compounds identified EOA, accounting for 96.87% the total, twenty-eight EOO, 99.46% total. For major monoterp...

In this study, chemical compositions of hydrodistilled essential oil and anti-inflammatory activities from the twigs of Cinnamomum osmophloeum Kaneh. were investigated for the first time. The chemical constituents of the twig essential oil were further analyzed by GC-MS and they were found to be L-bornyl acetate (15.89%), caryophyllene oxide (12.98%), gamma-eudesmol (8.03%), beta-caryophyllene ...

BACKGROUND Pycnocycla spinosa Decne. ex Boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. Thirty four components have been extracted from P. spinosa essential oil, of which several major constituents were found to show seasonal variation. OBJECTIVES The aim of this work is to evaluate the diurnal variation of its oil constituen...

This work describes the isolation and structural elucidation of compounds from the leaves of Myrcia tomentosa (Aubl.) DC. (goiaba-brava) and evaluates the antimicrobial activity of the crude extract, fractions and isolated compounds against bacteria and fungi. Column chromatography was used to fractionate and purify the extract of the M. tomentosa leaves and the chemical structures of the compo...
