Comparative Analysis of Volatile Oils from Lonicera japonica Thunb. var. chinensis wakey by HS-SPME and GC-MS

Method development by GC-ECD and HS-SPME-GC-MS for beer volatile analysis.

Two methods for the extraction, identification and quantification of the highest occurrence and lowest perception threshold off-flavours in fifteen different samples of Brazilian Pilsner beers were developed. For this purpose, headspace solid phase microextraction in combination with a gas chromatography coupled to a mass spectrometric detection (HS-SPME-GC-MS) as well as headspace extraction i...

Volatile Profiles of Honeys Using HS-SPME-GC-MS

Rapid determination of volatile compounds emitted from Chimonanthus praecox flowers by HS-SPME-GC-MS.

A novel rapid, simple and solvent-free method was developed for determination of the volatile compounds from the flowers of Chimonanthus praecox Link using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). The SPME conditions were firstly optimized and applied to sampling of the volatile compounds emitted from living Chimonanthus praecox L. flower...

Volatiles 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 ...

Analysis of Volatile Components of Cape Gooseberry (Physalis peruviana L.) Grown in Turkey by HS-SPME and GC-MS

Volatile components in cape gooseberry fruit at ripe stage were collected using headspace-solid phase microextraction, and analyzed by gas chromatography-mass spectrometry. Three solid phase microextraction fiber coatings (DVB/CAR/PDMS, CAR/PDMS, and PDMS/DVB) were tested for evaluation of volatile compounds. DVB/CAR/PDMS fiber showed a strong extraction capacity for volatile compounds and prod...
