Recent investigations have shown that plants have antioxidant properties and could decrease oxidative stress in different human diseases. The present work was identified the chemical composition compounds and evaluated the various antoxidative activities of Ferula-assa-foetida leaves hydroalcoholic extract (FLHE) and Ferula-assa-foetida leaves essential oil ...

The identification of drugs against the new coronavirus (SARS-CoV-2) is an important requirement. Natural products are substances that serve as sources beneficial chemical molecules for development effective therapies. In this study, 187 natural compounds from Algerian herbal medicines were docked in active site SARS-CoV-2 main protease. result indicates Piperitol, Warfarin, cis-calamenen-10-ol...

In developing countries, the risk of getting sick from eating food contaminated with Escherichia coli is very high. As a consequence multidrug resistance this bacterium, therapeutic alternative has been sought in plant kingdom. The Objective research was to evaluate antibacterial effect pot marigold (Calendula officinalis) essential oil (EO) on growth E. coli. Design/Methodology/Approach: activ...

The composition of the essential oils of Teucrium chamaedrys L. belongs to the family Lamiaceae, It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. In this research, essential oils of Teucrium chamaedrys L., extracted and measured at the different location by different methods of distillationand then were analyzed by GC and GC/MS. Investigation and com...

The first step in the conversion of the isoprenoid intermediate, farnesyl diphosphate (FDP), to sesquiterpene phytoalexins in cotton (Gossypium barbadense) plants is catalyzed by delta-cadinene (CDN) synthase. CDN is the precursor of desoxyhemigossypol and hemigossypol defense sesquiterpenes. In this paper we have studied the mechanism for the cyclization of FDP and the putative intermediate, n...

Pycnocycla spinosa aerial parts were collected weekly during four-month growth. Hydrodistillation and gas chromatography coupled with mass spectroscopy techniques were used for essential oil and sesquiterpenes investigation. Thirty-four components were identified, of which the characteristic sesquiterpenes were a -copaene, caryophyllene, a -humulene, b-ionene, d-cadinene, a -calacorene, caryoph...
