Turner, Lucy published the artcileInvestigating the Relationship of Genotype and Geographical Location on Volatile Composition and Sensory Profile of Celery (Apium graveolens), COA of Formula: C10H18O, the main research area is apium graveolens volatile composition genotype geog location; SPME GCMS; aroma; celery; harvest; phthalides; terpenes; volatile compounds.

Numerous varieties of celery are grown in multiple countries to maintain supply, demand and availability for all seasons; thus, there is an expectation for a consistent product in terms of taste, flavor, and overall quality. Differences in climate, agronomy and soil composition will all contribute to inconsistencies. This study investigated the volatile and sensory profile of eight celery genotypes grown in the UK (2018) and Spain (2019). Headspace anal. determined the volatile composition of eight genotypes, followed by assessment of the sensory profile using a trained panel. Significant differences in the volatile composition and sensory profile were observed; genotype and geog. location both exerted influences. Two genotypes exhibited similar aroma composition and sensory profile in both locations, making them good candidates to drive breeding programs aimed at producing varieties that consistently display these distinctive sensory properties. Celery samples harvested in the UK exhibited a higher proportion of sesquiterpenes and phthalides, whereas samples harvested in Spain expressed a higher aldehyde and ketone content. Studying the relationship between growing environment and genotype will provide information to guide growers in how to consistently produce a high-quality crop.

Chen, Zhipeng published the artcileA comparative study of volatile flavor components in four types of zaoyu using comprehensive two-dimensional gas chromatography in combination with time-of-flight mass spectrometry, Category: alcohols-buliding-blocks, the main research area is volatile flavor component zaoyu product gas chromatog.

Volatiles of four zaoyu (Chinese traditional fermented fish) products prepared from different species of marine fish were analyzed by headspace solid-phase micro-extraction (HS-SPME) and comprehensive two-dimensional gas chromatog. in combination with time-of-flight mass spectrometry (GC × GC/TOFMS). First, a 50/30Μ m DVB/CAR/PDMS was used and the influence of several parameters on the efficiency of HS-SPME such as extraction temperature, time, salting-out effect, and stirring were optimized, odor activity values (OAVs) of volatile compounds were computed based on the threshold values of aroma constituents; the characteristic volatiles and their odor characteristics of the four zaoyu were investigated. The results demonstrated that the most effective extraction of the analytes was obtained with a 40 min extraction at 50°C with the addition of 20% NaCl and stirring at 300 r/min. Under these conditions, a total of 288 volatile components were tentatively identified based on mass spectra and comparison of linear retention indexes in the four zaoyu products. Authenticated compounds included aldehydes, esters, alcs., ketones, furans, lactones, nitrogen compounds, sulfur compounds, terpenes, phenols, etc. Among the identified types of volatile compounds, the number of esters is the largest, whereas the content of aldehydes is the highest. The results of OAVs comparisons proved that both aldehydes and esters provided the most significant contribution to the aromas of zaoyu, and each zaoyu product had its own unique active flavor components. Moreover, the OAVs of active flavor compounds common to the four examined zaoyu varied significantly. Our results substantiated that GC × GC/TOFMS could provide a robust tech. means to understand the flavor characteristics of zaoyu and allow us to better evaluate and improve the flavor quality of the products with complex food matrix like zaoyu. The method present in this research is suitable to characterize the volatile constituents of aquatic products, and could also be used for component characterization of similar complex samples such as fermented fish and foods. Understanding the key aroma compounds of fermented fish and its formation mechanism could provide a guide of process optimization and flavor regulation, contributing to further studies related to volatile compounds in the field of food flavor anal.

Anastasaki, Eirini published the artcileElectrophysiological responses of Philaenus spumarius and Neophilaenus campestris females to plant volatiles, Application In Synthesis of 124-76-5, the main research area is Philaenus Neophilaenus Olea Polygala volatile electrophysiol; Aphrophoridae; Apiaceae; Apium graveolens; Cistaceae; Cistus creticus; Cynodon dactylon; Fabaceae; GC-EAD; Insect–plant interactions; Lolium arundinaceum; Medicago sativa; Neophilaenus campestris; Olea europea; Oleaceae; Olfactometer; Petroselinum crispum; Philaenus spumarius; Pinaceae; Pinus halepensis; Poaceae; Polygala myrtifolia; Polygalageae; Xyllela fastidiosa.

In the present study, we aim to identify volatile organic compounds (VOCs) that may act as semiochems. for these species. Using the dynamic headspace technique, we collected VOCs from Olea europaea L. and Polygala myrtifolia L., highly susceptible plant species to X. fastidiosa, Pinus halepensis Mill., a common plant where N. campestris is found during summer, and from host plant species that are used as cover crops or exist as natural vegetation in olive orchards, such as Cistus creticus L., Medicago sativa L., Cynodon dactylon (L.) Pers. In addition, antennae of P. spumarius females responded to camphor, limonene, 4-Me octane and sabinene. These compounds were found in the volatile profile of at least 5 out of 8 examined plant species. Behavioral bioassays using Y-tube olfactometry were performed on volatiles that elicited antennal responses during electrophysiol. studies. Among the compounds tested in behavioral studies, namely (-)-α-pinene, (+)-α-pinene, sabinene, (-)-S-limonene and (1R)-(+)-camphor, only the last one elicited a significant attraction response by P. spumarius females. The results achieved shed light on the VOCs from selected host plant species of X. fastidiosa that are perceived by two important insect vectors and a non-host plant, P. crispum. The identification of semiochems. for manipulating spittlebugs behavior contribute to the development of efficient monitoring tools for X. fastidiosa vectors.

Dimos, Nicole published the artcileCryoEM analysis of small plant biocatalysts at sub-2 Å resolution, COA of Formula: C10H18O, the main research area is Salvia borneol dehydrogenase BDH2 BDH1 cryo electron microscopy; borneol dehydrogenases; camphor; cryo-electron microscopy; green chemistry; high resolution; plant biocatalysts; terpenes.

Enzyme catalysis has emerged as a key technol. for developing efficient, sustainable processes in the chem., biotechnol. and pharmaceutical industries. Plants provide large and diverse pools of biosynthetic enzymes that facilitate complex reactions, such as the formation of intricate terpene carbon skeletons, with exquisite specificity. High-resolution structural anal. of these enzymes is crucial in order to understand their mechanisms and modulate their properties by targeted engineering. Although cryo-electron microscopy (cryoEM) has revolutionized structural biol., its applicability to high-resolution structural anal. of comparatively small enzymes has so far been largely unexplored. Here, it is shown that cryoEM can reveal the structures of plant borneol dehydrogenases of ∼120 kDa at or below 2 Å resolution, paving the way for the rapid development of new biocatalysts that can provide access to bioactive terpenes and terpenoids.

Cautela, Domenico published the artcileThe ancient neapolitan sweet lime and the calabrian lemoncetta locrese belong to the same citrus species, HPLC of Formula: 124-76-5, the main research area is citrus flavonoid volatile organic compound; Mediterranean sweet lime; Neapolitan limmo; Neapolitan “four citrus fruits” liqueur; agrobiodiversity; lemoncetta Locrese; taxonomy.

“”Neapolitan limmo”” is an ancient and rare sweet Mediterranean lime, now almost extinct but used until a few decades ago for the production of a fragrant liqueur called the “”four citrus fruits””. The objective of this work was to compare, through the use of chem. (flavonoids, volatile organic compounds, and chiral compounds) and mol. (DNA fingerprint based on RAPD-PCR) markers, the residual population of Neapolitan limmo with other populations of sweet limes, identified in Calabria and known as “”lemoncetta Locrese””. We report for the first time specific botanical characteristics of the two fruits and unequivocally show that the ancient sweet Mediterranean limes Neapolitan limmo and lemoncetta Locrese are synonyms of the same Citrus species. Owing to the biodiversity conserved in their places of origin, it will now be possible to recover, enhance and implement the use of this ancient sweet lime for agro-industrial purposes.

De Almeida E Silva, Beatriz published the artcileInteraction between mycorrhizal fungi and Meloidogyne javanica on the growth and essential oil composition of basil (Ocimum basilicum), Quality Control of 124-76-5, the main research area is Meloidogyne Ocimum mycorrhizal fungi essential oils.

Plant-parasitic nematodes and arbuscular mycorrhizal fungi (AMF) have been reported to alter the yield and chem. composition of basil (Ocimum basilicum) essential oil. The aim of this study was to evaluate the effectiveness of AMF to control the root-knot nematode Meloidogyne javanica in basil and to investigate the effects of nematode-AMF interactions on plant growth, phosphorus (P) absorption, and essential oil composition The experiment was conducted under greenhouse conditions following a completely randomized 3 x 2 factorial (two fungal species and an uninoculated control x inoculated and uninoculated seedlings) arrangement with 10 replicates. Substrates were inoculated with Claroideoglomus etunicatum, Rhizophagus clarus, or no fungi (control) and sown with basil seeds. After 20 days, half of the seedlings were inoculated with 4,000 M. javanica eggs. After 60 days, the vegetative parameters, P absorption, essential oil composition, nematode population d., AMF root-colonization efficiency, and AMF spore d. were determined The presence of AMF increased the basil’s fresh weight and ability to absorb P, while reducing the M. javanica reproduction In total, 21 compounds were identified in basil essential oil, the concentrations of which varied according to the treatments. The major components were eucalyptol, linalool, eugenol, β-elemene, trans-α-bergamotene, and τ-cadinol. Inoculation with AMF decreased the linalool levels but increased the amount of eucalyptol. Mycorrhizal plants showed increased shoot height, P uptake, and essential oil yield and a decreased nematode population d. in their roots.

Flamini, Guido published the artcileEssential oil composition of Salvia rosmarinus spenn. wild samples collected from six sites and different seasonal periods in Elba Island (Tuscan Archipelago, Italy), Synthetic Route of 124-76-5, the main research area is Salvia essential oil 18cineole camphene seasonal climate statistical analysis; 18-cineole; borneol; camphor; geographic origin; statistical analysis; α-pinene.

The hydrodistd. essential oils from eighteen samples of Salvia rosmarinus Spenn. collected in six localities of Elba Island (Tuscany, Italy) during three different seasonal periods were analyzed by GC-MS for the first time. Fifty-five components were identified, representing 96.8-99.6% of the total chem. composition All the tested essential oils were characterized by a high content of monoterpenes (oxygenated 49.2-80.3%; hydrocarbons 18.7-48.3%). Among them, 1,8-cineole (26.4-49.1%), α-pinene (4.5-34.8%), camphor (1.1-18.8%) and borneol (1.7-16.2%) were the main constituents. The high amount of 1,8-cineole/α-pinene/camphor/borneol may suggest the presence of an intermediate rosemary chemotype. Statistical anal. was also performed on the essential oil (EO) composition evidenced an expected difference depending on the collection seasons, to the geog. areas and soil composition A comparison with the essential oil composition from S. rosmarinus collected in all the other islands of Tuscan Archipelago (Italy) was also reported, together with a Multivariate Statistical Anal.
