The essential oils and aromatic water, known as Arak in traditional Iranian medicine, comes from the aerial part of Teucrium persicum Boiss., which is grown in Fars Province located in Iran. The samples were collected in summer and the oils and aromatic water were obtained through steam distillation. The chemical composition of the oils was analyzed using GC-MS. An analysis of the chemical...

The use of natural products as medicinal agents presumably predates the earliest recorded history. Ocimum sanctum L., is a plant which is used in several traditional medicine systems to cure various diseases. In this study aerial parts of Ocimum sanctum were collected on august 2014 from Shahr-e-Rey in Iran. Fresh and dry partsof plants essential oils were extracted with hydro-distillation and ...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of eight Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected from different pla...

This study evaluates the content of essential oils (EOs) and prenylated flavonoid Xanthohumol (XN) in extracts Slovenian hops, cultivar Aurora, obtained by using fluids different polarity. It is a continuation our previous work, investigating extraction bitter acids from hops. Extraction was conducted semi-continuously, sub- supercritical polarity, i.e., carbon dioxide (CO2) propane as non-pola...

Essential oils from Amazonian species are gaining increasing interest worldwide due to their medicinal and cosmetic applications; however, the relation among chemical constituents biological properties not well explored. Therefore, present research aims obtain an understanding of bioactivity compounds in essential plants Annonaceae family (Bocageopsis pleiosperma, Onychopetalum amazonicum, Unon...

Biodiversitas 22: 482-492. The yield in Algeria is low with an average 0.16 ± 0.017. chemical the was determined by GC-GC / MS analysis. Seventy-eight compounds were identified 92.3 26.4% total oil. α-pinene (58.72 14.45%)...

The potential of the biome caatinga (exclusive from northeastern Brazil) has been evaluated in recent research for application pharmaceutical industry. Among species medicinal plants caatinga, one can highlight Commiphora leptophloeos (umburana), which used as infusions and syrups by regional population inflammatory infectious diseases. Essential oils umburana leaves barks were obtained a Cleve...

Phytochemical analysis of 3 members the Urticaceae family (eg Pilea pumila, Laportea canadensis, and Boehmeria cylindrica) was conducted using GC-MS. P pumila L canadensis have several recorded historical medicinal uses by Native American tribes, whereas B cylindrica does not. This study to understand in terms chemical composition. Plant material, separated into aerial or root portions, dried e...

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...
