J. Am. Soc. Brew. Chem. 73(2):151-158, 2015 Linalool, an important substance in hoppy, aromatic beer, is one of the most aromatic components of essential oils in hops. Linalool concentration, among those of other substances, could be used to distinguish among hops varieties. As such, an effective, repeatable, and high-throughput method is required; a new method based on fluidized-bed extraction...

     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...

PURPOSE The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity, while attempts to characterize these properties in the laboratory date back the beginning of the XX(th) century. In the current study essential oils obtained from Pelargonium roseum (Geraniacea) were analyzed for their antibacterial and antifungal activities. METHODS The ...

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...

Essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. Lythrum salicaria has not been previously subjected to examination of its volatile oil. The present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using c...
