Volatile components of different periods and different parts of Dendrobium chrysotoxum based on GC-MS

Guangxi Zhiwu
In order to investigate the characteristics and release pattern of volatile components during flowering of Dendrobium chrysotoxum. In this study, solid-phase microextraction(SPME)combined with GC-MS was used to detect the volatile components of D ...

Composição química dos componentes voláteis de Capsicodendron dinisii Schwancke (Canellaceae) Chemical composition of volatile components of Capsicodendron dinisii Schwancke (Canellaceae)

Química Nova, 2010
The volatile components of the stem bark of Capsicodendron dinisii were obtained by hydrodistillation using a modified Clevenger-type apparatus. The chemical compounds were identified using the arithmetic index and confirmed by GC-MS.

Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

CHANGES IN VOLATILE COMPOSITION AND SENSORY PROPERTIES OF VUGAVA WINES AGED IN CROATIA OAK BARRELS [PDF]

Journal of Central European Agriculture, 2001
Vugava musts were fermented in medium-toasted Croatian barrique barrels (225 L) made from Quercus petrea and Q. robur oak wood. The oak species used in this research infl uenced the specifi c change of the aroma structure of Vugava wines.

Effect of freeze storage on the volátiles of butter

Grasas y Aceites, 1995
The changes in the volatile components of three butter samples during freeze storage for 7.5 months were studied. The storage had a significant effect on the carbonyl and lactone components analyzed.

Volatile Flavor Components of Kogyoku Apples

Agricultural and Biological Chemistry, 1984
A steam distillate of Kogyoku apple juice was extracted with ethyl ether. The extract was separated into its acidic and neutral fractions, and the neutral fraction was further separated into five fractions by column chromatography. All these fractions were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

Advanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Analysis of Volatile Flavor Substances in Different Leaf Positions of Mulberry Leaves Using HS-SPME-GC-MS Combined with GC-O

Shipin gongye ke-ji
To investigate the distribution of the 'grassy flavor' in mulberry leaves, the study focused on the 'Guangdong Mulberry No.11' cultivar, which was widely grown in the southern region of China. Analyzing the volatile components of different leaf positions

An Alternative Measure of Core Inflation [PDF]

We combine the ideas of the trimmed mean and the Edgeworth index to construct an alternative measure of core inflation named “Trim of most volatile components (TMVC)”. At each point of time this measure trims away the components of the price index, which
