|
| In the volatile oil are terpenes and sesquiterpenes of medicinal and aromatic properties. |
|
| The molecular family it concentrates on is the terpenes, which are used as fragrances and flavours. |
|
| The fact that their structures can be built up from isoprene units justifies their classification as terpenes. |
|
| Diuretics can be found in terpenes, phenolics and alkaloids. |
|
| The second pilot project will use a catalytic process to remove volatile sulphur compounds and terpenes from pulp-making water. |
|
| They include nitrogen dioxide, formaldehyde, and a wide range of alkanes, cycloalkanes, terpenes, aromatic compounds, and hydrocarbons. |
|
|
|
| This plant produces poisonous chemicals called terpenes. |
|
| Many of these mycodiesel hydrocarbons are terpenes, a chemically diverse class of compounds produced by many plants, fungi, and bacteria. |
|
| Sustained heat and pressure drives off terpenes and results in the formation of amber. |
|
| The emitted VOC belonged exclusively to the substance classes of terpenes and aldehydes. |
|
| Humulene is one of the main terpenes in a high-grade hoppy aroma but, most of all, the interaction between the various aroma components is important. |
|
| The arrangement of isoprene units in phytol is identical with that in vitamin A, a monocyclic diterpene derivative, and is typical of the head-to-tail arrangement of isoprene units found in most terpenes. |
|
| This process consists in the separation of terpenes and sesquiterpenes which are products with little or no aroma, tasteless and easily alterable. |
|
| Process for obtaining terpene flavourings, characterized in that an S. cerevisiae mutant, blocked in the pathway of ergosterol synthesis and which secretes aromatic terpenes, is cultured on a suitable culture medium. |
|
| These chemicals may be by-products of basic metabolic pathways, such as alcohols and terpenes produced by green plants or lactic acid produced by mammals. |
|
| Mountain cheeses are also richer in terpenes than lowland cheeses. |
|
| Lately we have been interested intensely by the changes that some substances of the group of the terpenes and of the camphors undergo when exposed to light, especially through hydrolytic processes. |
|
| This database contains infrared spectra of a variety of biochemicals such as peptides, amino acids, carbohydrates, nucleic acids, sugars, lipids, steroids, terpenes, alkaloids, glycosides, carotenoids, flavonoids, etc. |
|
| It produces abundant biomass and can be used for a multitude of derived bio-products: terpenes to control termites, bio-molecules used in pharmaceuticals and cosmetics, and even bricks for heating and fuel from bagasse. |
|
| This database provides scientists with a representative collection of organic compounds used in the manufacture of flavors and fragrances, natural product oils, synthesized fragrance compounds, terpenes, and some fixatives. |
|
| Because terpenes may produce explosive mists when sprayed, they should only be used in spray applications with proper safety precautions, such as inert gas blanketing. |
|
| All the major terpenes produced from the functional TPSs were detected in the VOC profiles of the four endophytes grown on potato dextrose. |
|
| For example, linalool and coumarin are both naturally occurring compounds that can be inexpensively synthesized from terpenes. |
|
| Metabolic fate of dietary terpenes from Eucalyptus radiata in common ringtail possum. |
|
| Like terpenes, Dichlorobenzene is rarely found in outdoor air samples, indicating the source is predominantly from indoor consumer goods. |
|
| Eden uses terpenes, which are chemicals found in a wide variety of plants and flowers. |
|
|
|
| The content of terpenes in GR-R shown in table 1 is remarkable indeed. |
|
| As eukaryotes, fungi possess a biosynthetic pathway for producing terpenes that uses mevalonic acid and pyrophosphate as chemical building blocks. |
|
| The wood extractives are fatty acids, resin acids, waxes and terpenes. |
|
| Iris rhizomes also contain notable amounts of terpenes, and organic acids such as ascorbic acid, myristic acid, tridecylenic acid and undecylenic acid. |
