“…In contrast, Australia imports about 204,001,778 stems at a cost of about $63,838,000 in 2016 [5]. The main industrial application of roses comes from the perfume industry, which relies on different scented rose varieties [6] [7] [8] [9] [10]. Among these varieties are the Hybrid Tea rose and Floribunda rose cultivars, both of which are modern roses.…”

A method involving Headspace solid-phase microextraction (HS-SPME) fiber combined with gas chromatography (GC) coupled with flame ionization detection (FID) and gas chromatography with mass spectrometry (GC-MS) was developed and optimized to investigate volatile organic compounds (VOCs) from different tissues (flowers, leaves, stems, rhizosphere and whole plants) of Floribunda and Hybrid Tea roses (intact and cut). Three-phase fiber 50/30 µm divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) was used. Two types of chambers (Tedlar bag and glass jar) were evaluated for collection of VOCs and glass jar was selected. Absorbed compounds on the fiber were completely desorbed in the GC injector port at three desorption times (5, 10 and 15 min), and 5 min at 250˚C was used. The maximum extraction efficiency for flowers tissues (equilibrium absorption) was achieved 2 h after fiber exposure in the headspace for intact and cut Floribunda and Hybrid Tea flowers. Under the optimized HS-SPME and GC-FID/MS conditions, 1h extraction time was chosen for intact and cut Floribunda and Hybrid Tea leaves and stems. The results demonstrated that 5 cm depth was selected for root and soil part (rhizosphere) for both rose cultivars, and 6 h and 12 h extraction time of VOCs from rhizosphere was achieved for Floribunda and Hybrid Tea, respectively. One hour was chosen for VOCs released from whole rose plants for both cultivars. In this study, the VOC profiles of two rose cultivars were characterized by the optimized HS-SPME-GC method. The different tissues of rose plants gave wide range of the VOCs; also the chromatograms of different cultivars were quite different and the specific VOC pattern of rose types depends on the species. Results from this study demonstrate the feasibility of this method for identifying VOCs from two rose cultivars and the potential use of this method for physiological studies on rose plants or on other floriculture plants.

“…Nowadays Gas Chromatography (GC) is playing an important role in the metabonomics research. 4,5 Type II diabetes (DM2) is a typical metabolism disorder disease with the very high frequency of 1.5-2.5% in the Western hemisphere. Some of the changes in the concentrations of the metabolites are detectable in blood serum and in urine even when the diabetic patients are well controlled by therapy.…”

Background: Type II diabetes has become a serious threat to human health in recent years. Among adults above 20 years old in China, the prevalence rate of diabetes is 9.7%. Thus, it is imperative to study the mechanisms underlying type II diabetes to develop effective therapeutic treatments. Objective: To examine metabolic changes in a rat model of type II diabetes and explore mechanisms underlying the beneficial effects of traditional Chinese medicine (TCM) in this model. 120 rats were divided into four groups, including a control group, a high-fat diet group (high-fat diet and streptozotocin injection), a TCM group (high-fat diet, streptozotocin injection, followed by TCM administration), and a rosiglitazone maleate group (high-fat diet, streptozotocin injection, followed by rosiglitazone maleate administration). Metabolites in urine samples from 1-3 weeks (time point 1) and 4-6 weeks (time point 2) of drug administration were compared by gas chromatography-mass spectrometry (GC-MS). Results: Our results showed that in the high-fat diet group, at time point 2, the levels of dihydroxybenzoic acid, L-ascorbic acid, D-gluconic acid, octadecanoic acid, and glutaric acid in urine were significantly higher than at time point 1. In the TCM group, at time point 2, the urine levels of L-ascorbic acid were markedly lower than at time point 1. Conclusion: Our studies demonstrated that examining urine metabolic changes provided important insights into the mechanisms underlying type II diabetes as well as the therapeutic effects of TCM.

Эфирные масла являются продуктами природного происхождения, которые находят самое разнообразное применение в различных областях промышленности. Высокая стоимость, трудоемкость производства и широкое использование приводят к тому, что в продаже наряду с качественными эфирными маслами часто встречают фальсифицированные. Применение поддельных масел повышает их опасность для человека, в связи с чем установление подлинности эфирных масел имеет большое значение. В обзоре проведен анализ опубликованных работ и нормативных документов, посвященных вопросам определения подлинности и выявления фальсификации эфирных масел. Рассмотрен компонентный состав эфирных масел, его вариабельность в зависимости от места произрастания эфиромасличного растения и технологии выделения масла. Обсуждены основные способы фальсификации эфирных масел и спектр используемых для этого приемов, необходимость применения соответствующих методов исследования, позволяющих контролировать подлинность продукции. Проведен анализ литературы и нормативной базы, регламентирующей качество эфирных масел, существующих методов определения их подлинности, указывают достоинства и недостатки. Особое внимание уделено методу масс-спектрометрии изотопных отношений, как наиболее перспективному, вследствие высокой точности и возможности применения для исследования практически любого типа масла. Приведены основные теоретические положения исследования стабильных изотопов и их фракционирования, принципиальные особенности методов измерения. Подтверждено широкое использование метода масс-спектрометрии изотопных отношений на практике конкретными примерами с демонстрацией новых возможностей данного метода, связанных с использованием изотопного профилирования и комбинированных методов изотопного анализа. Отмечена важность для определения подлинности масел информации об изотопном составе их компонентов, который является индикатором любых искусственных процессов, происходящих с эфирным маслом в результате фальсификации.
