Terpenoids form the largest and stereochemically most diverse class of natural products, and there is considerable interest in producing these by biocatalysis with whole cells or purified enzymes, and by metabolic engineering. The monoterpenes are an important class of terpenes and are industrially important as flavors and fragrances. We report here structures for the recently discovered Strept...

ferulago angulata subsp. carduchorum (boiss. & hausskn.) d.f. chamb is a perennial species of the family apiaceae and is locally used as a flavouring agent and for some medicinal properties. the essential oil of this plant if found to possess antibacterial and antifungal activities. the present study is aimed to determine constituents of essential oils from inflorescence of four f. angulata sub...

Plants synthesize numerous classes of natural products that accumulate during development and are thought to function as constitutive defenses against herbivores and pathogens. However, little information is available about how the levels of such defenses are regulated. We measured the accumulation of monoterpenes, a model group of constitutive defenses, in peppermint (Mentha x piperita L.) lea...

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...

The essential oil from the leaves of Juglans regia L. (Juglandaceae) growing wild in Kashmir (India) was obtained by hydro-distillation and analysed during different stages of growth ranging from April to October. The analysis was carried out by a combination of capillary GC-FID and GC-MS analytical techniques. Both qualitative and quantitative differences were observed in the essential oil col...

OBJECTIVE This study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of Murraya koenigii leaves from the south region of Tamilnadu, India. Matherials and Methods: Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) analysis of the essential oil result was indicates the 33 different compou...

Essential oils are complex mixtures of volatile components produced by the plant secondary metabolism and consist mainly of monoterpenes and sesquiterpenes and, to a minor extent, of aromatic and aliphatic compounds. They are exploited in several fields such as perfumery, food, pharmaceutics, and cosmetics. Essential oils have long-standing uses in the treatment of infectious diseases and paras...

The effects of essential oil from Eucalyptus camaldulensis flowers oil on melanogenesis and the oil's antioxidant characteristics were investigated. Assays of mushroom and cellular tyrosinase activities and melanin content of mouse melanoma cells were performed spectrophotometrically, and the expression of melanogenesis-related proteins was determined by Western blotting. The possible signaling...
