Rose oil is traditionally produced by the water distillation of Rosa damascena and high economic value due to low essential yield. It therefore a common target for adulteration, which can cause harm consumers. Current standards authenticity control only consider analysis major components overlook minor quality markers as well enantiomeric ratio terpenes, have proven useful in originality determination. The aim this study was development two analytical GC-FID methods 21 29 rose analytes including major, chiral on DB-wax BGB 178 30% CD (chiral) capillary column, respectively. total run time both within 60 min. For all analytes, % bias at lower upper calibration range varied from -7.8 13.2% -13.1 5.2% analysed column 0.5 13.3% -6.9 7.0% column. successfully separated enantiomers (+/-)-camphene, (+/-)-rose oxide, (+/-)-linalool, (+/-)-citronellol (+/-)-citronellyl acetate, diastereomers citral β-damascenone. Both were applied 10 authentic samples enantiomeric/diastereomeric ratios, content components, determined. identity further confirmed GC-MS.

Selection of Garden Roses to Improve the Ecosystem Services They Provide

Horticulturae, Journal Year: 2022, Volume and Issue: 8(10), P. 883 - 883

Published: Sept. 27, 2022

With pronounced morphological and phenological diversity, garden roses have always been part of urban plantings. The significance in ornamental utilitarian (edible) horticulture can significantly be amended with novel ecosystem services, by shifting their breeding targets towards more than aesthetic nutritional value. Thus the aim this paper was to investigate possibilities newly bred (within past decade) from ‘Mella’ series as a possible ornamental, disease tolerant bee attracting cultivars recommended ecosystems, adding values current services. Research goals were determine characteristics; honey wild bees’ abundance its correlation rose floral resistance/tolerance main fungal diseases; suitability greenery providing multiple Plant material included seven series. Analyses complete morphological—qualitative quantitative characterization plant flower traits, fragrance panel scoring volatile components analyses, counts bees visiting flowers different species potential pollinators. Based on obtained results significant variability vegetative generative characteristics noted investigated roses. ‘naturalistic’ overall appearance, comparable roses, differed height habitus, number type flowers, leaf coloration glossiness, but ‘Barbie Mella’ ‘Ruby positioned most decorative ones. highly scored for fragrance, divergent records mixed compounds, characterized balanced ratio (almost 1:1:1) between aromatic alcohol + terpenoids, straight-chain alkanes long-chain alkanes. In relation bee’s attraction, combination height, (single, simple), diameter accessibility seems crucial, rather any characteristic solely. As an outstanding bee-attractor should promoted disease-tolerant cultivar. Due values, tolerance visitations, ‘Barbie’, ‘Ruby’, ‘Ducat’ ‘Exotic’ planted semi-natural gardens/landscapes, concomitantly contributing services—provisioning, regulating, cultural supporting. Until worldwide availability, other ‘Mella’-like cultivated likewise.

Do Abiotic Stresses Affect the Aroma of Damask Roses?

Plants, Journal Year: 2023, Volume and Issue: 12(19), P. 3428 - 3428

Published: Sept. 28, 2023

Roses are popular ornamental plants all over the world. Rosa damascena Mill., also known as damask rose, is a well-known scented rose species cultivated to produce essential oil. The oils obtained high in volatile organic compounds (VOCs), which demand across pharmaceutical, food, perfume, and cosmetic industries. Citronellol, nonadecane, heneicosane, caryophyllene, geraniol, nerol, linalool, phenyl ethyl acetate most important components of Abiotic factors, including environmental stress generated by agricultural practises, frequently exert selective impact on particular floral characteristics, hence influencing overall quality quantity products. Additionally, it has been observed that existence exerts notable chemical composition abundance aromatic present roses. Therefore, understanding factors affect biosynthesis VOCs, especially those representing aroma scent response abiotic important. This review provides comprehensive information plant taxonomy, an overview volatolomics involving profiles, describes influence stresses VOCs rose.

Exploring new dimensions: Single and multi-block analysis of essential oils using DBDI-MS and FT-IR for enhanced authenticity control

Analytica Chimica Acta, Journal Year: 2023, Volume and Issue: 1277, P. 341657 - 341657

Published: July 25, 2023

Essential oils (EOs) are complex mixtures of volatile hydrocarbons with a wide range applications in the pharmaceutical, fragrance and food industry. The composition EOs is highly variable can affect their quality pharmaceutical efficacy. Moreover, high economic value EOs, such as those obtained from Rosa damascena, make falsification misclassification lucrative business. Consequently, adulterations lead to serious health consequences for consumers. While current control methods involve analysing chromatographic profile or comparing Fourier transform infrared (FT-IR) spectra, these be time-consuming lack sensitivity. To address issues, we compared state-of-the-art methods, including gas chromatography flame ionization detection (GC-FID) quantification enantiomeric ratio determination, FT-IR spectrometry dielectric barrier discharge coupled triple quadrupole mass spectrometer (DBDI-MS), chemometric single- multi-block approach.Our results show that best classification accuracy 94.7% R. damascena samples was using GC-FID combined partial least square discriminant analysis (PLS-DA). Comparatively, ratios did not improve accuracy. In contrast, fragmentation data DBDI-MS (Q3), which acquired fraction time without extensive sample preparation, achieved 84.2%. We also found combining parent ion (Q1) sequentially orthogonalized squares linear (SO-PLS-LDA) model improved accuracy, respective single-block PLS-DA models.Overall, our study demonstrates DBDI, an ambient method, has significant potential high-throughput screening. When MS, it produce comparable accuracies conventional while offering added benefits speed convenience. As such, promising tool EO control.
