Download or read book Terpenes and Terpenoids written by Shagufta Perveen and published by BoD – Books on Demand. This book was released on 2018-12-19 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terpenes belong to the diverse class of chemical constituents isolated from materials found in nature (plants, fungi, insects, marine organisms, plant pathogens, animals and endophytes). These metabolites have simple to complex structures derived from Isopentyl diphosphate (IPP), dimethyl allyl diphosphate (DMAPP), mevalonate and deoxyxylulose biosynthetic pathways. Terpenes play a very important role in human health and have significant biological activities (anticancer, antimicrobial, anti-inflammatory, antioxidant, antiallergic, skin permeation enhancer, anti-diabetic, immunomodulatory, anti-insecticidal). This book gives an overview and highlights recent research in the phytochemical and biological understanding of terpenes and terpenoid and explains the most essential functions of these kinds of secondary metabolites isolated from natural sources.
Download or read book Terpenoids Structure Biogenesis and Distribution written by V. C. Runeckles and published by Elsevier. This book was released on 2013-10-22 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Phytochemistry, Volume 6: Terpenoids: Structure, Biogenesis, and Distribution covers the advances in the chemistry and biochemistry of terpenoids, and the use of information regarding the occurrence of such compounds in genetics and population ecology. The book discusses the applications of physical methods to some structural and stereochemical problems in terpenes and steroids; novel sesquiterpenes isolated in composites; and the chemistry and biogenesis of the quassinoids (Simaroubolides). The text then describes the recent developments in the biosynthesis of plant triterpenes; the mechanisms of indole alkaloid biosynthesis, recognition of intermediacy and sequence by short-term incubation; and the biochemistry and physiology of lower terpenoids. The genetic and biosynthetic relationships of monoterpenes; and the confirmation of a clinal pattern of chemical differentiation in Juniperus virginiana from terpenoid data obtained in successive years are also encompassed. Botanists, biochemists, and people involved in the study of phytochemistry will find the book invaluable.
Download or read book A Fragrant Introduction to Terpenoid Chemistry written by Charles S Sell and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terpenoids play an important part in all our lives, from Vitamin A and hormones to perfumes and pharmaceuticals. This book provides an introduction to terpenoid chemistry, concentrating on the lower terpenoids, but the basic principles taught are also the foundation for the chemistry of the higher terpenoids. Coverage includes: the biogenesis of terpenoids; some of the history of the field; the principles of structural determination; and the importance of stereochemistry and stereoselective synthesis. Carbocation chemistry is introduced, as are the principles of total and partial synthesis. Finally, industrial chemistry (both discovery chemistry and chemical process development) is discussed, using the volatile terpenoids of perfumery to illustrate basic concepts. Ideal as both an introduction to terpenoid chemistry and as a refresher course, A Fragrant Introduction to Terpenoid Chemistry, with its real-life problems and appreciation of the relevance of chemistry to everyday life, will prove invaluable to students, lecturers and industrialists alike.

Book excerpt: In this collection, terpenes in oregano, mainly represented by the essential oils, are extensively documented for their antimicrobial, antifungal, antiviral, antioxidant, anti-inflammatory and anticancer properties, with the goal of describing the biological properties of terpenes from oregano and their mechanism of action. Next, the authors focus on solid acid catalysts as potential heterogeneous catalysts for terpenes conversion into fragrances and flavours, replacing homogenous ones. Different reactions, such hydration, alkoxylation, esterification, isomerization and cyclization of terpenes over heterogenous catalyts will be reviewed. Afterwards, turpentine (consisting of the volatile terpenes fraction from conifer wood) is analyzed because of its place as the most widely produced essential oil. Lastly, the authors discusses the effects of terpene-rich essential oils. Although several studies describe the cardioprotective effects of these essential oils, a systematic review is lacking. Therefore, a compilation of these studies is presented with special focus on the hypotensive, vasorelaxant, modulation of ion channels, anti-dyslipidaemic, and antiplatelet aggregation effects as well as the protective effects against myocardial infarction.

Excerpt: ...this alcohol as identical with oxy-2-hexahydro-p-cymene (tetrahydrocarveol), which was prepared by Baeyer in the reduction of dihydrocarveol, and by Wallach by the reduction of carvenone. The results of Wallach's1 researches fully establish Semmler's view. Carvotanacetone unites with hydrogen sulphide in ammoniacal solution;2 the product melts at about 95. Carvotanacetoxime, C10H18NOH, is obtained from crude carvotanacetone, as already indicated; it crystallizes from methyl alcohol, and melts at 92 to 93. It is optically inactive (Wallach Wallach obtained an oxime having the same melting point (93 to 94) from the fraction of thuja oil, which boils at 220 to 230. Carvotanacetone semicarbazone forms orthorhombic tablets or acute prisms, and melts at 177 (Baeyer3). According to Harries, the oxaminoxime of carvotanacetone sinters at 155 and melts at 162; it was not obtained quite pure, hence Harries 4 regards it as probable that carvotanacetone is a mixture of the racemic form of dihydrocarvone with other compounds. When carvotanacetone is oxidized with a dilute solution of potassium permanganate, it yields pyruvic and isopropylsuccinic acids. From this fact Semmler2 concludes that carvotanacetone is an orAo-terpene ketone, and that the pseudo-ketone corresponding to it is found in terpenonef C10H16O (obtained from tetrahydrocarvone). 11.

Available in PDF, EPUB and Kindle. Book excerpt: Many of the terpenes compounds are naturally occurring organic products abundant in plants, which have been employed for centuries as odorants because of their aromatic qualities. In the last decades, their valuable properties have attracted growing interest in the pharmaceutical area. In fact, a large number of the worlds population uses plant extracts or their active compounds for health related purposes. Due to the continuous research efforts on terpenes compounds, numerous advances have been made in many aspects including advanced extraction and processing approaches, molecule structure analysis, usage for flavour enrichment, and most importantly, its potential pharmaceutical applications. This book manages to cover many of the recent developments. The potential of some monoterpenes has been reviewed for their use as substrates to obtain new natural flavour compounds with economic and commercial interest.
