“…Compound identification was made by comparing their mass spectra with those in the Wiley library and authentic external standard compounds. Moreover, their retention indices were compared to those in the NIST (National Institute of Standards and Technology) Chemistry web book (http://webbook.nist.gov/ chemistry/) and/or other published articles on plant volatiles analyzed in the same stationary phase (Demyttenaere et al 2004;Senatore et al 2004;Pino et al 2008;Ibrahim et al 2010).

The effects of yeheb (Cordeauxia edulis Hemsl.) leaf extract on feeding and oviposition by diamondback moth (DBM) (Plutella xylostella L.) and the behavior of DBM parasitoid, Cotesia vestalis (Haliday), were studied. Volatile organic compounds (VOCs) from the headspace of intact and DBMdamaged broccoli plants sprayed with yeheb extracts (YE) were also analyzed. Larval feeding and growth, and oviposition by adult DBM were strongly inhibited by the extract. Cotesia vestalis were attracted to volatile blends from intact or DBM-damaged broccoli plants sprayed with YE over intact plants sprayed with water or methanol. Analyses of VOCs in the headspace of broccoli plants revealed that both intact and DBM-damaged plants sprayed with YE showed remarkable differences in sesquiterpene compounds compared to intact control treatments. These combined negative effects of YE on DBM fitness together with positive effects on the parasitoid show that yeheb is a potential source of compounds for use in integrated pest management to control damage caused by DBM.

“…Additionally, it has been demonstrated in the literature that some enzymatic pathways are finished at other volatile products like heptanone and hexanone beside or instead of the C 8 compounds [31]. Other authors have also shown that terpenes and sesquiterpenes are useful bioindicators of the mould activity [28,44]. Thus, it can be determined that all of the aforementioned groups of compounds are bioindicators that can be used for the detection of the vegetative mycelium because they distinguish between active and inactive fungi.…”

The main purpose of these studies was to assess the possibility of applying the technique of solid phase microextraction (SPME)-gas chromatography (GC)-mass spectrometry (MS) to detect the activity of moulds on historical objects, based on the analysis of microbial volatile organic compounds (MVOCs). The studies were performed for selected species of moulds, which were inoculated onto model samples of silk, cellulose, parchment and wool that had been prepared on microbiological medium, in vials for headspace sampling. After a few days of incubation, the MVOCs in the vials were sampled by using SPME fibre, and then they were analysed in the GC-MS system. The acquired chromatograms were qualitatively and quantitatively assessed, and it was ascertained that among the identified compounds are markers of mould activity which can be used to detect the vital mould growing on actual historic items. This usefulness of the method was additionally confirmed by analysis of MVOCs emitted by keratinolytically active mould inoculated on a sample of historical wool prepared in a Petri dish without a medium.

“…HSSE has been applied to headspace sampling of a wide variety of interesting sample types. These include aromatic and medicinal plants [270], chiral monoterpenes in essential oils in combination with enantio-MDGC-MS [271], coffee [272] and volatile metabolomics from toxigene fungi [273,274].…”

Today, a wide variety of techniques is available for the preparation of (semi-) solid, liquid and gaseous samples, prior to their instrumental analysis by means of capillary gas chromatography (GC) or, increasingly, comprehensive two-dimensional GC (GC 9 GC). In the past two decades, a large number of 'modern' sample-preparation techniques has been introduced, which have partly superseded their 'classical' counterparts. These novel techniques include off-line and on-line (sometimes semi-or fully automated) procedures, and exhaustive extraction as well as equilibrium techniques. In order to improve overall performance, aspects such as essentially organic solvent-less approaches, large-volume injection and miniaturization receive increasing attention. In most recent applications, mass spectrometric or element-selective detection have been used. The present review discusses the advantages and disadvantages, and relative performance, of most of the modern samplepreparation techniques and cites a number of illustrative applications for each of them.
