    ABSTRACT: Nanocapsules loaded with bioactive compounds derived from medicinal plants have numerous possibilities in the development of biochemical delivery systems. Elaeagnus angustifolia L., commonly known as Russian olive, is used in traditional medicinal in the Middle East as an analgesic for arthritis and joint pain. Because E. angustifolia contains vitamin A, vitamin B, abundant calcium, and vitamin K, an effective coagulant, it has been considered as potentially beneficial in wound healing and scar formation, as well as in the treatment or prevention of osteoporosis. Nanocapsules containing an E. angustifolia-filled core can be fabricated employing polymerization. In this process, nanocapsules are prepared using poly ethylene glycol–poly butylene adipate–poly ethylene glycol (PEG-PBA-PEG) as a shell surrounding a core of E. angustifolia and olive oil. In this study, the relative proportions of polymer and oil, concentrations of polymer and bioactive compound, and presence or absence of various surfactants in different concentrations were investigated in relation to the particle size of the final product. A comparison of samples obtained using the surfactants Tween 80, Tween 60, poly vinyl alcohol (PVA), mixed Tween 80 and PVA, and mixed Tween 80 and Tween 60 showed Tween 80 to result in the smallest particle size. An oil-to-polymer ratio of 1:0.25 resulted in the smallest nanoparticle size. Smaller nanoparticles sizes were obtained using lower concentrations of polymer and higher concentrations of the bioactive compound. Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, particle size analysis, and scanning electron microscopy were used to identify and characterize the nanocapsules.

    ABSTRACT: In this study we tested the anti‐Candida effect of Thymbra capitata essential oil (EO) plus chitosan and developed a new therapeutic tool. The classical check‐board methodology was used to determine the anti‐Candida activity that results from product association. The incorporation of T. capitata EO in a chitosan hydrogel, using lactic acid as the solvent, resulted in the TCCH hydrogel. Its anti‐Candida activity was studied by using 18 Candida strains, according to the CLSI M27‐A3 micromethod and the lethal effect according to the protocol proposed by Canton et al. The TCCH activity in acidic conditions corresponding to a healthy vaginal pH (4.5) was also tested. Its anti‐Candida activity upon pre‐formed biofilm metabolism and biomass was tested using the semi‐quantitative XTT reduction assay and the crystal violet staining assay, respectively. The hydrogel interaction with the yeast surface was shown by confocal microscopy. TCCH hydrogel presented an acidic nature, compatible with the vaginal pH. The association of both natural products revealed an additive effect upon Candida and TCCH hydrogel showed to be active upon both Candida planktonic and biofilms. No cell invasion was observed. Being a new product with an acidic nature compatible with the vaginal environment and presenting a potent effect upon Candida planktonic and biofilm cells, TCCH hydrogel could represent a valuable tool for the treatment of vulvovaginal candidosis.

    ABSTRACT: We report the enantioselective synthesis of the ambergris odorants (+)‐(S)‐γ‐ionone, (+)‐(S)‐γ‐dihydroionone, (−)‐α‐ambrinol, (+)‐(S)‐γ‐coronal, (−)‐(S)‐γ‐homocyclogeranyl chloride and (+)‐(S)‐γ‐homocyclogeraniol. At first, the enantio‐enriched (4R,6S)‐4‐acetoxy‐γ‐ionone was prepared starting from commercial racemic ionone alpha by means of a chemo‐enzymatic process. This chiral building block was then converted into (S)‐γ‐dihydroionone which was used as the starting material for the synthesis of the aforementioned odorants.

    ABSTRACT: Phytochemicals have been isolated from extracts of various Xylopia species (Annonaceae) growing wild in the African rainforest. In contrast, no phytochemical investigations have been reported to date on Xylopia rubescens Oliv. The aim of the present work was to describe the composition of X. rubescens leaf oil. Analysis of the leaf oil has been undertaken by a combination of chromatographic and spectroscopic techniques. Three new compounds have been isolated and their structures elucidated as furanoguaia‐1,4‐diene, furanoguaia‐1,3‐diene and (8Z,11Z,14Z)‐8,11,14‐heptadecatrien‐2‐ol. One other compound is reported for the first time as a natural compound. The oil composition was dominated by both furanoguaiadienes (34.2% and 11.4%, respectively) and by (8Z,11Z,14Z)‐8,11,14‐heptadecatrien‐2‐one (12.8%). The composition of X. rubescens leaf oil varied dramatically from those of the essential oils isolated from other Xylopia species. Copyright © 2013 John Wiley & Sons, Ltd.

    ABSTRACT: The antioxidant activity of 18 phenols, including standard antioxidants (e.g. butylated hydroxytoluene, α‐tocopherol) and fragrance molecules (e.g. eugenol, thymol) has been evaluated by measuring the rate constants for their reaction with the DPPH• (2,2‐diphenyl‐1‐picrylhydrazyl) radical in m‐xylene. Correlation with the bond dissociation energies supports the involvement of the hydrogen atom transfer mechanism. The radical trapping ability of α‐tocopherol, eugenol and isoeugenol has been investigated in five solvents of different polarity and in a series of homologous alcohols. In comparison to α‐tocopherol, the increase of the observed scavenging kinetics for eugenol and isoeugenol in alcohols suggests that the sequential proton loss electron transfer (SPLET) takes place. The addition of acetic acid eliminates the SPLET mechanism and confirms its predominance in polar solvent. The major effects of the pK a of fragrant phenols and of the solvent dielectric constant on the SPLET mechanism are discussed. Some fragrance phenols, such as mesitol and eugenol, show a significant reactivity towards the DPPH• radical in m‐xylene, which is more pronounced for eugenol derivatives in alcohols.

    ABSTRACT: The manufacture of high‐quality whole‐grain products is challenged by poor flavour attributes, such as excessive bitterness. In a recent study our group characterized eight compounds that contributed to the bitterness of a whole‐wheat bread sample. The goal of this study was to investigate the chemical profile of these bitter compounds in relation to the perceived bitterness of four commercial whole wheat breads and one refined wheat bread. Highly significant correlations (α = 0.01) were observed between the perceived bitterness in the crust and the quantity of 5‐(hydroxymethyl)furfural (r 2 = 0.93) and 2,3‐dihydro‐3,5‐dihydroxy‐6‐methyl‐4(H)‐pyran‐4‐one (r 2 = 0.95). In the crumb, the bitterness was correlated with the amount of l‐tryptophan (r 2 = 0.91). In summary, both Maillard‐ and fermentation‐derived compounds were identified as potential chemical markers to predict bitterness of whole‐wheat bread. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: ABSTRACTA low‐density polyethylene membrane pouch method was developed to extract volatile flavour compounds from butter oil prior to gas chromatography–mass spectrometry analysis. The butter oil represented oil‐based sample with complex flavour compounds. It was placed in the pouch and heat‐sealed for extraction in diethyl ether at 40°C for 1 h. The extraction mechanism can be explained by the molecular sieve effect. The extracted volatile flavour compounds are essential for butter oil aroma, e.g. fatty acids and lactones. The percent recoveries of fatty acids and lactones by this method were 1.00–1.74% and 10.1–11.2%, respectively. Sensory evaluation of the aroma recombinate and butter oil indicated the promise of this extraction technique. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: The preparation of optically active 3‐hydroxy‐2‐octanone was examined by Sharpless asymmetric dihydroxylation of a silyl enol ether derived from 2‐octanone. (R)‐3‐Hydroxy‐2‐octanone was obtained in 68% yield and 87.8% ee when AD‐mix‐β was used as an oxidant, while the (S)‐enantiomer was produced in 69% yield and 77.3% ee from AD‐mix‐α. The characteristic odour of the optically active products was evaluated by chiral gas chromatography–olfactometry. (R)‐3‐Hydroxy‐2‐octanone has a mushroom‐like, fresh grass odour, while the (S)‐enantiomer presents a mushroom‐like, earthy note. Aroma extract dilution analysis was applied to determine the flavour dilution factors of the two enantiomers. The flavour dilution factor of the (R)‐enantiomer was 1024, which is much higher than that of (S)‐enantiomer (256). They obviously differ in odour intensity. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: Sideritis spp. is a member of the Labiateae family, used in traditional folk medicine and as a calming tea preparation. Dichloromethane extracts of the aerial parts of four Sideritis species were prepared, and the volatile fractions were separated via solvent-assisted flavour evaporation distillation. In vitro electrophysiological techniques were used to investigate the physiological effects of these aroma extracts on ionotropic γ-aminobutyric acid receptors (GABAA) in comparison to extracts of Lavandula spp. (lavender) obtained by the same approach. The plant extracts of Sideritis spp. and Lavandula spp. increased the maximal current responses gated by the agonist GABA, both in whole cell patch clamp recordings as well as in two electrode voltage clamp assays. Thereby, the volatile fractions caused a dose-dependent enhancement of GABAergic currents. Differences in activity between the various species were probably due to variations in odorant composition, either on a qualitative or quantitative basis. Thus, the plant material contains volatile organic compounds, which are able to modulate a GABA-mediated response and thereby possibly contribute to a sedative effect in vivo.

    ABSTRACT: Ylang‐ylang essential oil is an important raw material for the fragrance industry. Despite its economic importance, to the best of our knowledge, no study has yet been undertaken to assess the chemical polymorphism of the different production areas. This underestimated variability is an interesting source of raw material for perfumers. That is why the variation in the chemical composition of four fractions of the essential oils extracted from Cananga odorata, grown in four locations Grande Comore, Mayotte, Nossi Bé and Ambanja, was studied. A total of 119 compounds, representing 85.7–96.4% of the total essential oil composition, were identified using gas chromatography–mass spectrometry and quantified by gas chromatography with a flame ionization detector. Thirty‐two compounds previously unreported in ylang‐ylang essential oil were identified. The distinction between the Comoros and Madagascar groups was made on the basis of the chemical classes. It was possible to significantly distinguish the Grande Comore and Mayotte essential oil samples, as well as the Ambanja and Nossi Bé essential oil samples, on the basis of their main compounds. The aromatic compounds profile for the origin of each essential oil fraction was established. Regression trees were built, allowing the provenance of the essential oils prepared at the laboratory level to be easily differentiated on the basis of a limited number of major compounds.

    ABSTRACT: Release of fragrant molecules from poly(ethylene oxide) (PEO) grafted chitosan particles could be controlled in a switchable manner through the thermo‐responsive hydration/dehydration of the PEO corona of the spheres that resulted in the de‐aggregation/aggregation among particles and corresponded to an on/off fragrant release switch. In water, mPEO–chitosan self‐assembled into spherical particles with the mPEO corona covering the surface and vanillin and citral could be loaded into the particles. The mPEO–water interaction took place at temperatures lower than the lower critical solution temperature (LCST) value and resulted in de‐aggregation among spheres which enabled release of the loaded fragrance molecules, whilst mPEO–mPEO interactions occurred at temperatures higher than the LCST value and resulted in aggregation among spheres which also halted the fragrance release. This thermal switch could be tuned to a desired temperature by adjusting the salt concentration. After the release of all fragrances, the thermo‐responsive carriers could be refilled again.
