Eight essential oils of Chinese medicinal herbs (Angelica sinensis, Curuma aeruginosa, Cyperus rotundus, Eucalyptus robusta, Illicium verum, Lindera aggregate, Ocimum basilicum, and Zanthoxylum bungeanum) were obtained by hydrodistillation and the essential oil of Eucalyptus robusta leaves was analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 22 components of the essential oi...

Salvia mirzayanii is member of Lamiaceae family, which distributes only in south of Iran. Phytochemical composition of essential oil isolated by hydro distillation from the aerial parts of Salvia mirzayanii Rech. & Esfand. grown wild and cultivated in Iran were determined using Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC/MS). Forty nine components were identified in the...

The essential oils of the aerial part of two Asteraceae species, namely Euryops arabicus Steud. and Laggera decurrens (Vahl.) Hepper and Wood, were studied by GC and GC/MS. In parallel the antimicrobial and antioxidant activities were evaluated. The investigation led to the identification of 48 and 44 compounds for both plants, respectively. The essential oil of E. arabicus was rich in oxygenat...

Demethylisoencecalin (1) and caleins A (4) and C (5) (3.16-31.6 mg/kg, p.o.), the major components from an infusion of Calea ternifolia controlled postprandial glucose levels during an oral sucrose tolerance test (OSTT, 3 g/kg) in normal and nicotinamide/streptozotocin (NA/STZ, 40/100 mg/kg) hyperglicemic mice. The effects were comparable to those of acarbose (5 mg/kg). During the isolation of ...

The extracts and fractions of leaves and branches of Protium hebetatum D. C. Daly (Burseraceae) were investigated for their antibacterial activity and chemical composition. The methanol extract of branches (EMG) was considered active against the Escherichia coli and the Proteus vulgaris, showing an inhibition zone of 13 mm, and was selected for bioassayguided phytochemical fractionation. From t...

Aims: The aim of this study was to isolate essential oils from the fruits of Fissistigma bracteolatum and Fissistigma maclurei (Annonaceae) and investigate the volatile constituents present they contained. Study Design: The study involves the hydrodisitillation of essential oils from the air-dried fruit samples of F. bracteolatum and F. maclurei and analysis of their chemical compositions by GC...

The anticancer and anti-inflammatory activities of wild-sage (Lantana camara) leaves essential oil were evaluated against various human cell lines. In this regard, steam hydro-distillation technique was used for extraction. Chemical characterization L. camara (LCEO) done by GC-MS, forty one chemical components (98.69%) detected in LCEO. major constituents caryophyllene oxide (19.63%), (6.68%), ...

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...

Bay laurel leaves, also known as bay are an important herb in many cuisines around the world. In addition to their use cooking, leaves have been used for medicinal properties and thought anti-inflammatory antimicrobial effects. Gas chromatography/mass spectrometry (GC-MS) device was determine secondary metabolites essential oil of samples kept at different temperatures (−22, −20, −18, 2, 4, 6, ...

The essential oils were obtained by hydro-distillation from the roots and rhizomes of two umbelliferous species Ligusticum sinense and L. jeholense. They were analyzed for their chemical composition by GC and GC-MS. 5-Oxo-δ-4-decahydrobenzindene (50.1%), ligustilide (16.4%), β-phellandrene (7.8%), myristicine (5.5%), and spathulenol (3.3%) were the major compounds of the 25 identified component...
