The essential oils of ginger (Zingiber officinale) and turmeric (Curcuma longa) contain a large variety of terpenoids, some of which possess anticancer, antiulcer, and antioxidant properties. Despite their importance, only four terpene synthases have been identified from the Zingiberaceae family: (+)-germacrene D synthase and (S)-β-bisabolene synthase from ginger rhizome, and α-humulene synthas...

گیاه رازک Humulus lupulus  از منطقه خود آفرین در حاشیه رود ارس جمع آوری و خشک گردید و از روش کلونجر جهت اسانس گیری استفاده شد.پس از تعیین میزان اسانس، ترکیبهای موجود در آن توسط دستگاه کروماتوگرافی گازی (GC) و دستگاه کروماتوگرافی گازی متصل به طیف سنج جرمی (GC-MS) مورد تجزیه و تحلیل قرار گرفت. در این تحقیق از 100 گرم گل خشک 0.03  درصد اسانس(با محاسبه رطوبت) استخراج گردید. در این اسانس 25 ترکیب ک...

Essential oils (EOs) with a wide spectrum of antibacterial activities have been suggested as potent alternative sources for controlling multidrug-resistant bacteria. This paper presented the evaluation anti-H. pylori activity EOs from rhizomes Zingiber officinale, Curcuma zedoaria, longa and Alpinia officinarum. The Eos, obtained by steam distillation method, were evaluated their minimal inhibi...

Seventeen microbial species including 10 fungal taxa, two yeasts and five bacteria, were isolated from freshly prepared orange, guava and banana juices kept in open bottles at room temperature for 7 days. Eight different essential oils, from local herbs, were tested for their antimicrobial activity against these test organisms. The essential oils of Cymbopogon citratus, Ocimum basilicum and Ori...

Terpenoids, naturally occurring compounds derived from isoprene units present in pine oleoresin, are a valuable source of chemicals used in solvents, fragrances, flavors, and have shown potential use as a biofuel. This paper describes a method to extract and analyze the terpenoids present in loblolly pine saplings and pine lighter wood. Various extraction solvents were tested over different tim...

alpha-Zingiberene synthase (ZIS), a sesquiterpene synthase gene that was isolated from lemon basil (Ocimum basilicum L.), encodes an enzyme that catalyzes the formation of alpha-zingiberene, and other sesquiterpenes, from farnesyl diphosphate. Transgenic tomato fruits overexpressing ZIS under the control of the fruit ripening-specific tomato polygalacturonase promoter (PG) accumulated high leve...

A crystalline compound [{(1,5-(1,3)benzodioxol-5yl)-1-oxo-2,4pentadienyl}-piperidine] and few sesquiterpenes ( Caryophyllene, β–bisabolene, δ –Cadinene, Elemol, (-)Cedreanol, αEudesmol ) were obtained from the toluene extract of dried fruits of Piper nigrum. This is for the first time piperine has been extracted from the cold toluene extract of Piper nigrum along with few other sesquiterpenes. ...

Endophytic fungi are ubiquitous plant endosymbionts that establish complex and poorly understood relationships with their host organisms. Many endophytic fungi are known to produce a wide spectrum of volatile organic compounds (VOCs) with potential energy applications, which have been described as "mycodiesel". Many of these mycodiesel hydrocarbons are terpenes, a chemically diverse class of co...
