Aromatic profiles of Thymus hyemalis and Spanish T. vulgaris essential oils by GC–MS/GC–O
Thymus hyemalis L. and Spanish T. vulgaris subsp. vulgaris shrubs are characterized by a great chemical intraspecific variability among plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. Because of this, clones of T. hyemalis and T. vulgaris were used to monitor seasonal variations in their aromatic composition o...
متن کاملSolubility investigation of ether and ester essential oils in water using spectrometry and GC/MS
Background and objectives: Essential oils (volatiles) are aromatic oily liquids prepared from different parts of plants and demonstrate various therapeutic and cosmetic properties. The dissolution of essential oils are not desirable in water, therefore the aim of this research was evaluation and selection the best co-solvents for increasing their solubility and bio availability...
متن کاملSolubility investigation of ketone and phenol essential oils in water using spectrometry and GC/MS
Background and objectives: Essential oils are used for their flavors and fragrances and their medicinal properties in food, cosmetic, agriculture and pharmaceutical industries. This study was focused on the selection of the best solvent(s) which would increase water solubility of ketone and phenol classes of essential oils. Methods: The solubility of s...
متن کاملAnalysis of the essential oils of Coriandrum sativum Using GC-MS coupled with chemometric resolution methods.
The essential oils extracted from Coriandrum sativum L. were analyzed by GC-MS coupled with chemometric resolution methods. Through the chemometric resolution methods, peak clusters were uniquely resolved into the pure chromatographic profiles and mass spectra of each component. Qualitative analysis was performed by comparing the pure mass spectra with those in the NIST 05 mass spectral library...
متن کاملEnhanced Essential Oils Analysis Using a High Performance Benchtop GC/MS System Application Note
A gas chromatograph (GC) coupled with a mass spectrometer (MS) forms a powerful tool for high quality quantitative and qualitative analysis. However, GC/MS analysis of complex mixtures such as essential oils often is a time-consuming task due to limitations in techniques and instrumentation. Faster analyses of these mixtures are possible by coupling the 5973A mass selective detector (MSD) with ...
