Analysis of flavor volatiles of some Iranian rice cultivars by SPME-GC-MS
A combined gas chromatography–mass spectrometry (GC–MS) with headspace solid-phase microextraction (HS-SPME) method has been employed for the analysis of the flavor volatiles of some Iranian rice cultivars (Domsiah, Deylamani, Hashemi, Shirodi and Tarom). The samples were grown in different cities of Mazandaran province. The sampling procedure and chromatographic conditions were same for all sa...
متن کاملIdentification of volatiles from Pinus silvestris attractive for Monochamus galloprovincialis using a SPME-GC/MS platform
INTRODUCTION A myriad of volatile organic compounds (VOCs) released by terrestrial vegetation plays an important role in environmental sciences. A thorough chemical identification of these species at the molecular level is essential in various fields, ranging from atmospheric chemistry to ecology of forest ecosystems. In particular, the recognition of VOCs profiles in a context of plant-insect ...
متن کاملDifferentiation of wines according to grape variety and geographical origin based on volatiles profiling using SPME-MS and SPME-GC/MS methods.
Among methods to detect wine adulteration, profiling volatiles is one with a great potential regarding robustness, analysis time and abundance of information for subsequent data treatment. Volatile fraction fingerprinting by solid-phase microextraction with direct analysis by mass spectrometry without compounds separation (SPME-MS) was used for differentiation of white as well as red wines. The...
متن کاملVolatiles of Lysimachia paridiformis Var. Stenophylla, Lysimachia fortumei and Lysimachia chikungensis by HS-SPME-GC-MS.
BACKGROUND Lysimachia paridiformis Var. Stenophylla mainly contain flavonoid constituents. Flavonoids and benzoquinones are the main compounds in L. fortumei Maxim. The objective of this paper was to study the volatile compounds of leaves in L. paridiformis Var. Stenophylla, L. fortumei and L. chikungensis for the first time. MATERIALS AND METHODS Volatiles were extracted by the manual solid ...
