Rapid determination of volatile constituents of Michelia alba flowers by gas chromatography–mass spectrometry with solid-phase microextraction

Application of HS‐SPME and GC‐MS to Characterization of Volatile Compounds Emitted from Osmanthus Flowers

“…Recently, a novel sampling technique, solid-phase microextraction (SPME) introduced by Pawliszyn et al has been developed for analysis of floral fragrances. [9][10][11][12][13][14][15][16][17][18] Headspace SPME with GC-MS has been demonstrated to be a rapid, simple, sensitive and solvent-free method for analysis of volatiles in plant emissions. In our previous studies, headspace SPME was developed for the determination of methyl salicylate released from tomato plants infected by tobacco mosaic virus and volatile compounds from flowers.…”

“…In our previous studies, headspace SPME was developed for the determination of methyl salicylate released from tomato plants infected by tobacco mosaic virus and volatile compounds from flowers. 18,19 In this study, we developed SPME and GC-MS with a sampling chamber devised (FIG.1) for the characterization of volatile compounds released by two varieties of Osmanthus flowers of O. fragrans var. latifolius and O. fragrans var.…”

Determination of the volatile constituents of ChineseCoriandrum sativum L. by gas chromatography—Mass spectrometry with solid-phase microextraction

“…SPME is a rapid, simple, inexpensive and solvent-free technique very suitable for the analysis of volatile and semivolatile compounds, and the technique is proving to be increasingly useful in organic analytical chemistry. Recently, there has been increasing use of SPME for the extraction of organic compounds from several matrices: the volatile compounds of mango and tomato juices [2,3], the sulfur compounds in beer and of garlic [4 6], the freshness of fish [7], the hydrocarbons in blood and urine [8], the free volatile fatty acids in waste waters [9], the pesticide residues in fruits and fruit juices [10], water samples [11,12] or serum [13], the volatile compounds of Michellia alba flowers [14] and spices [15]. The fiber adsorbed organic compounds were usually transferred to a gas chromatograph or gas chromatography-mass spectrometer to desorb at high temperatures.…”

Analysis of the volatile constituents ofApium graveolens L. andOenanthe L. by gas chromatography-mass spectrometry, using headspace solid-phase microextraction

“…In our previous work, the volatile compounds of Michellia alba flowers, mango juice and Coriandrum sativum L were studied using headspace-SPME-GC-MS [12][13][14]. In the present paper we describe the use of the technique using a polydimethylsiloxane-divinylbenzene (PDMS-DVB) fiber for the extraction of the volatile compounds of celery and dropwort.…”
