Abstract:
Terpenes are naturally occurring compounds produced by plants that are of great commercial interest in the food, agricultural, cosmetic, and pharmaceutical industries due to their broad spectra of antibacterial, antifungal, anthelmintic, membrane permeation enhancement, and antioxidant biological activities. Applications of terpenes are often limited by their volatility and the need for surfactants or alcohols to produce stable, soluble (non-precipitated) products. Yeast particles (YPs) are hollow, porous microspheres that have been used for the encapsulation of terpenes (YP terpenes) by passive diffusion of terpenes through the porous YP cell walls. We here report the development of a second generation YP encapsulated terpene technology that incorporates the stimuli-responsive control of terpene release using biodegradable pro-terpene compounds (YP pro-terpenes). YP terpenes and YP pro-terpenes were both produced, in which high levels of carvacrol, eugenol, thymol and geraniol were encapsulated. The YP pro-terpenes show higher encapsulation stability than YP terpenes due to pro-terpenes being non-volatile solids at room temperature and stable in suspensions at neutral pH. YP pro-terpenes and YP terpenes were evaluated for biological activity in antibacterial, antifungal and anthelmintic assays. The YP pro-terpenes retained the full biological activity of the parent terpene compound.

Abstract:
The key point of our work was evaluating the impact of terpene alcohols on the aroma expression of terpenes recombination in Chrysanthemum essential oils. Using pure commercial products, various aromatic recombinations were prepared, consisting of terpenes recombination and six terpene alcohols, all the concentrations found in Chrysanthemum essential oils. There were five groups of terpene alcohols mixtures performed very interesting with the addition or omission tests. The “olfactory threshold” of the terpenes recombination had a notable decrease when adding isoborneol, d-Fenchyl alcohol respectively through the Feller’s additive model analysis. Furthermore, the descriptive test indicated that the addition of terpene alcohols mixture had the different effect on fruity, floral, woody, green, and herbal aroma intensity. Specifically, when isoborneol was added to the terpenes recombination in squalane solution, it was revealed that isoborneol had a synergy impact on herbal and green notes of the terpenes recombination and masked the fruity note.

Abstract:
Terpene deployment was examined in a population of Eucalyptus polybractea (R.Baker) trees. Eucalyptus polybractea is a terpene-accumulating species, which stores terpenes in oil glands beneath the leaf surface. Using regression analysis, we showed that leaf thickness, measured as leaf mass per area (LMA), influenced terpene content, apparently through regulation of gland dimensions, and thus, gland volume. We also examined how environmental factors affected terpene content through regulation of both LMA, and therefore, storage capacity, and the supply of resources for terpene synthesis. Neither water stress, measured using carbon isotope ratios as an indicator, nor nutrient stress, measured as foliar nitrogen and phosphorus content, accounted for observed variation in either terpene content or LMA. Phenolic content, measured as a possible competing carbon sink, did not account for variation in terpene content, and variation in environmental stresses could not account for differences in growth rate. However, both terpenes and total carbon-based secondary metabolites (terpenes and phenolics) showed positive correlations with growth, suggesting plants gain a growth advantage by deploying greater amounts of secondary metabolites.

Abstract:
Twenty-one volatile terpenes and terpenoids were found in Monomorium chinense Santschi (Hymenoptera: Formicidae), a native Chinese ant, by using headspace solid-phase microextraction (HS-SPME) coupled with gas-phase chromatography and mass spectrometry (GC-MS), which makes this ant one of the most prolific terpene producers in insect. A sesquiterpene with unknown structure (terpene 1) was the main terpene in workers and neocembrene in queens. Terpenes and terpenoids were detected in poison, Dufour’s and mandibular glands of both workers and queens. Worker ants raised on a terpene-free diet showed the same terpene profile as ants collected in the field, indicating that de novo terpene and terpenoid synthesis occurs in M. chinense.

Abstract:
Terpene levels were measured in bark and wood samples of Sitka spruce (Picea sitchensis (Bong.) Carrière) trees. The trees that had been selected as early or late flushing were subjected to artificial wounding to simulate attack by the white pine weevil, Pissodes strobi (Peck). Samples were taken at four times during the growing season: before wounding, shortly after wounding, and two times later in the season. Terpenes were extracted with hexane and quantified by capillary gas chromatography. There were no significant differences in total bark terpenes between early- and late-flushing trees or between control and wounded trees over all sampling times. There were no significant differences in total wood terpenes between early- and late-flushing trees or among sampling times, but a statistically significant difference was found between control and wounded trees. Eleven individual terpenes accounted for the majority of the terpenes in the extracts. Four bark terpenes showed significant differences with sampling time, two with flushing class, and none with treatment. Five wood terpenes showed significant differences with sampling time, two with flushing class, and nine with treatment. We concluded that flushing had only a minor effect on bark and wood terpene profiles and that wounding significantly increased terpene concentration in wood shortly after injury.

Abstract:
The spatial concentration gradient of volatile terpenes near the surface of spruce needles was determined. The gradient comprised four orders of magnitude in the distance of 0 to 0.2 mm. The reaction of ozone with terpenes in this surface region was estimated. Within a diffusion limited reaction time of 1.4 milliseconds the chemical conversion amounts to one per thousand. Therefore it is not expected that one will find exceptional high concentrations of phytotoxic ozonolysis products, peroxides for example, in this micro environment.

Abstract:
Terpenes are phytochemicals found in multiple plant genera, especially aromatic herbs and conifers. Terpene content quantification is costly and complex, requiring the extraction of oil content and gas chromatography analyses. Near infrared (NIR) spectroscopy could provide an alternative quantitative method, especially if calibration can be developed with the spectra of dried plant material, which are easier and faster to acquire than oil-based spectra. Here, multispecies NIR spectroscopy calibrations were developed for total terpene content (mono- and sesquiterpenes) and for specific terpenes (α-pinene, β-pinene and myrcene) with five conifers species ( Picea glauca, Picea rubens, Pinus resinosa, Pinus strobus and Thuja occidentalis). The terpene content of fresh shoot samples was quantified with gas chromatography. The NIR spectra were measured on freeze-dried samples (n = 137). Using a subset of the samples, modified partial least squares regressions of total terpene and the three individual terpenes content were generated as a functions of the NIR spectra. The standard errors of the internal cross-validations (values between 0.25 and 2.28) and the ratio of prediction to deviation ratios (RPD values between 2.20 and 2.38) indicate that all calibrations have similar accuracy. The independent validations, however, suggest that the calibrations for total terpene and α-pinene content are more accurate (respective coefficient of determination: r2 = 0.85 and 0.82). In contrast, calibrations for β-pinene and myrcene had a low accuracy (respectively: r2 = 0.62 and 0.08), potentially because of the low concentration of these terpenes in the species studied. The calibration model fits (i.e., r2) are comparable to previously published calibration using the spectra of dried shoot samples and demonstrate the potential of this method for terpenes in conifer samples. The calibration method used could be useful in several other domains (e.g. seedling breeding program, industrial), because of the wide distribution of terpenes and especially of pinenes.

Abstract:

Utsläpp av lättflyktiga organiska föreningar (VOC) är ett växande mijlöproblem. Biofiltrering är ett relativt billigt sätt att rena luft förorenad med VOC. Biofiltrering har också en fördel i att föroreningen helt bryts ned och inte endast övergår i en annan form. Rapporten beskriver arbetet kring två biofilter av kolonntyp. Mikroberna som användes kom från främst träflis och jord. Som förorening användes limonen och α-pinen. Analys skedde med gaskromatografi.

Vidare undersöktes om närvaro av silikonolja i filterbädden påverkade resultatet Reningskapaciteten uppgick i filtret utan olja till ca 10 - 12 g/m3.h under de första 25 dagarna i drift och ökade därefter till ca 15 - 20 g/m3.h. Motsvarande data för det oljeberikade filtret är ca 15 - 20 g/m3.h i båda fallen


Emissions of volatile organic compounds are a growing environmental problem. Biofiltration is a relatively cost efficient method to purify air polluted with VOC:s. Biofiltraion also has the benefit of completely degrading the pollutants rather than just transferring them into another phase/form. This report describes the work on two biofilters of column type. The microbes used were extracted from wood chips and soil. As pollutants limonene and α–pinene were used.

Furthermore, it was investigated how the presence of silicone oil in the filter bed affected the filtering results. The filtering capacity in the non oil enriched filter was during the first 25days 10-12 g/m3h and thereafter some 15-20 g/m3h. The efficiency of the oil enriched filter was stable at 15-20 g/m3h.

Abstract:
Le manuscrit de thèse traite de la synthèse totale de molécules naturelles de structures particulièrement intrigantes. Deux familles de molécules naturelles issues du monde marin ont été ciblées dans ce travail : les halichonadines et les araiosamines.- La famille des halichonadines nous plongent dans le domaine des terpènes d’origine marine. Isolées d’éponges du genre Halichondria, deux structures ont particulièrement retenues notre attention : les halichonadines K et L. En effet, non seulement, ces deux molécules complexes contiennent une partie terpénique de type eudesmane (halichonadine C, un isonitrile naturel) mais aussi un cœur central de nature peptidique constitué, notamment, d’une pipéridine disubstituées par des fonctions acide carboxylique. Une partie est dédiée à comprendre comment dans la nature, des molécules de type isonitrile sont produites et peuvent réagir dans des voies de biosynthèse. Par ailleurs, le travail expérimental s’est organisé de la façon suivante :1- Concevoir une synthèse efficace de l’halichonadine C. Une stratégie au départ de la santonine est développée. La présence d’un groupement isopropyle sur la structure finale s’est avérée poser un nombre important de problèmes. Cependant, un composé très avancé a été obtenu figurant tout le squelette et l’atome d’azote nécessaire à la finalisation de la synthèse de l’halichonadine C.2- Concevoir une synthèse du cœur central permettant de contrôler la stéréochimie relative des deux fonctions carboxyliques en alpha de l’atome d’azote. Plusieurs stratégies ont été étudiées faisant appel notamment à une double addition de Michael ou à des réactions inspirées de la synthèse de la tropinone. Le cœur central est ainsi accessible en un nombre très limité d’étapes.Les résultats sont très encourageants et la quasi-totalité des pièces du puzzle sont là pour entrevoir rapidement la synthèse totale des halichonadines K et L.- La partie consacrée aux araisoamines (A-D, extraites d’éponges du genre Clathria) est exploratoire et permet de proposer des pistes synthétiques prometteuses pour l’accès bio-inspiré à ces molécules naturelles constituants un défi pour le chimiste. Un des défis relevés dans le travail est de concevoir des analogues synthétiques d’intermédiaires biosynthétiques très réactifs tels que des indoles aldéhydiques très instables. Une méthode pour générer in situ de telles entités a été étudiée. Les premières expériences ont été appliquées à la synthèse des « pyridiniums de Discodermia » et apparaissent prometteurs.Les travaux menés s’inscrivent dans « l’art de la synthèse totale » mais sont aussi toujours en lien avec le souci de mieux comprendre « chimiquement » comment des architectures moléculaires complexes s’assemblent au cours des voies de biosynthèse des substances naturelles
The work described in this PhD dissertation is dedicated to the total synthesis of intriguing natural product structures. Two distinct families of natural substances of marine origin have been targeted in this work: the halichonadins and the araiosamines.- With the halichonadins, we plunge into the marine terpene chemistry. Isolated from sponges of the genus Halichondria, two structures have particularly drawn our attention: halichonadins K and L. Indeed, besides two subunits of terpene origin (namely halichonadin C, a natural isonitrile) with an eudesmane skeleton, a central core of peptidic origin is also original (especially a carboxylic acid disubstituted piperidine ring). A part of the work is dedicated to understanding how, in nature, isonitrile natural products may be formed and may react. The experimental part is organized according to the two following topics:1- Devise an efficient and straightforward total synthesis of halichonadin C. A strategy starting from santonin has been studied and developed. The presence of an isopropyl pending group has attracted many synthetic problems. Anyhow, an advanced intermediate comprising the whole skeleton and the crucial nitrogen atom of the target has been reached and provides good hopes for the access to halichonadin C.2- Conceiving a strategy of the stereocontroled access to the central piperidine ring of halichonadins K and L. Several strategies have been evaluated including the recourse to double Michael additions and reactions inspired by Robinson’s tropinone synthesis. The peptidic central core is now accessible in a limited number of steps.Most of the pieces of the puzzle are in our hands at the end of this PhD to secure a rapid access to the complex targets that constitutes halichonadins K and L.- The chapter dedicated to araiosamines (A-D, isolated from sponges of the genus Clathria) is exploratory and allows to propose promising strategies for a bio-inspired synthesis that constitutes true challenges for the organic chemists. One of the challenges to take up is to prepare highly reactive indole aldehyde units that could be foreseen as chemical equivalents of postulated biosynthetic intermediates. A method to generate in situ such units is studied. The first applications have been directed to the synthesis of “Discodermia pyridiniums” and appear to be promising towards the total synthesis of these molecules.The work conducted during this PhD take place in the framework of the “art of total synthesis”. But, in our strategies, the chemical understanding of biosynthetic pathways is never far away

Abstract:
Terpenes are natural products that have several biological and pharmacological properties that are directly related to their chemical structures. In the structural determination of organic molecules, Nuclear Magnetic Resonance (NMR) is used on a large scale. The chemical shift (δ) being the most important parameter. The present study aims to develop and test (the elemol molecule will be used for this purpose) δ scaling factors from 13C to terpenes, based on linear regressions. 10 complex sesquiterpene molecules were selected with the unmistakably determined structures (confirmed with X-ray crystallography). The geometries were optimized at the B3LYP / 6-311 + G (d, p) level, in the gaseous phase, and the δ will be obtained at the PBE0 / aug-cc-pvdz level with three different approaches GIAO, CSGT and IGAIM, in phase gaseous and liquid, where the PCM model (polarized continum model) was used. The TMS (tetramethylsilane) was used as a reference and the experimental data of 13C were obtained in chloroform. The results of scaled RMS for the terpenes used to generate the scaling factors show that when the effects of the solvent are taken into account, even implicitly, there is an improvement in the reproduction of experimental data. However, the difference in scaled RMS values is not large enough to justify taking into account interactions with the solvent, at least with the PCM model. It is interesting to note that with the level of theory PBE0 / aug-cc-pvdz, the GIAO method presented a lower performance than the other 2 used. Another interesting point is that its calculation time, according to the simulations generated in this work, was, on average, 30% greater than the CSGT and IGAIM. Thus, for studies with terpenes, with this level of theory, the use of the GIAO method is not indicated.

Abstract:
Typical furniture inside residential or office buildings is made from materials that emit terpenes. Terpenes react with ozone in the air, and produce secondary organic aerosols (SOA). During summer the concentration of SOAs may exceed by a factor of two to five times the concentration in outdoor air. The high concentration of SOA could adversely influence the human health. The air ventilation inside the room as well as the particles’ Brownian motion causes the particles to mix and coagulate. The coagulation of SOAs due to their collision leads to an increase in sizes in time. Coagulation, surface growth and nucleation of particles are the mechanisms which change the particle size and concentration distribution. The particle size distribution is important as large particles sediment rapidly and they are not a health threat for residents while fine and ultra fine particles stay suspended in the air and could enter the human respiratory system. A typical office room with furniture and a manikin was modeled in this study. The indoor airflow was simulated and was followed by the analysis of dispersion and coagulation of particles using the moment method. Two types of ventilation systems were modeled, and the results were compared discussed.
