“…CENIVAM has studied Colombian plants widely used in popular medicine or in culinary, for example, anise [14], oregano [15], rue [16,17], and other species introduced from Asia, such as lemongrass, citronella, ginger, citrics [18][19][20], vetiver, and ylang-ylang [21][22][23], as well as several native species, among others, Copaifera officinalis [24], Spilanthes americana [25], Lepechinia schiedeana [26], Lippia alba [27], Xylopia americana [28], Hyptis umbrosa [29], Callistemon speciosus (sims) DC. [30], Swinglea glutinosa [31], Satureja viminea [32], and Lippia origanoides [33], with emphasis on the comparative study of extraction methods [34][35][36][37][38][39][40]. Table 1 summarizes the composition of several Lippia EOs, according to compound families.…”

Researchers from several Colombian universities have joined efforts for over 15 years to characterize the composition and biological properties of more than a thousand samples of essential oils (EOs) obtained from aromatic plants collected during at least 30 botanical outings in different regions of Colombia. This chapter presents a brief description of essential oil extraction and chemical characterization techniques, followed by a representative list of references to publications on EO composition obtained from tropical aromatic plants that grow in Colombia. Opportunities for the development of interesting products for the pharmaceutical, cosmetics, hygiene, and food industries are illustrated with a few selected works on the evaluation of cytotoxicity, antioxidant, antiviral, antigenotoxic activities, and repellence of these essential oils.

“…The use of both in vivo and in vitro SPME has been suggested for the isolation of the volatile metabolites from sources ranging from fungi and algae to human subjects, due to its versatility in the extraction of volatile compounds and its ability to limit interferents present in complex matrices by pre‐concentrating analytes that are present even at low concentrations . SPME is an extraction technique that is typically employed when it is necessary to determine the identity of volatile metabolites involved in dynamic processes that occur continuously and systematically, causing no interruption in the living system being investigated .…”

In vivo determination of the volatile metabolites of saprotroph fungi by comprehensive two-dimensional gas chromatography

In this work, we discuss the use of multiway principal component analysis combined with comprehensive two-dimensional gas chromatography to study the volatile metabolites of the saprophytic fungus Memnoniella sp. isolated in vivo by headspace solid-phase microextraction. This fungus has been identified as having the ability to induce plant resistance against pathogens, possibly through its volatile metabolites. Adequate culture media were inoculated, and its headspace was then sampled with a solid-phase microextraction fiber and chromatographed every 24 h over seven days. The raw chromatogram processing using multiway principal component analysis allowed the determination of the inoculation period, during which the concentration of volatile metabolites was maximized, as well as the discrimination of the appropriate peaks from the complex culture media background. Several volatile metabolites not previously described in the literature on biocontrol fungi were observed, as well as sesquiterpenes and aliphatic alcohols. These results stress that, due to the complexity of multidimensional chromatographic data, multivariate tools might be mandatory even for apparently trivial tasks, such as the determination of the temporal profile of metabolite production and extinction. However, when compared with conventional gas chromatography, the complex data processing yields a considerable improvement in the information obtained from the samples.

“…Indeed, method development with automated SPME has several advantages over manual SPME methodology. For instance, superior extraction time reproducibility allows for the development of faster nonequilibrium extractions, an otherwise unattainable feat, in terms of reproducibility, when using a nonautomated method . Also, since autosamplers can run 24 h a day, a manual SPME method can be considered inconvenient when a considerable volume of samples needs to be processed .…”

Until recently, multiple solid-phase microextraction fibers could not be automatically desorbed in a single gas chromatographic sequence without manual intervention from an operator. This drawback had been a critical issue, particularly during the analysis of numerous on-site samples taken with various fiber assemblies. Recently, a Multi-Fiber Exchange system, designed to overcome this flaw found in other commercially available autosamplers, was released. In the current research, a critical evaluation of the Multi-Fiber Exchange system performance in terms of storage stability and long-term operation is presented. It was established in the course of our research that the Multi-Fiber Exchange system can operate continuously and precisely for multiple extraction/injection cycles. However, when the effect of residence time of commercial fibers on the Multi-Fiber Exchange tray was evaluated, results showed that among the evaluated fiber coatings, Carboxen/polydimethylsiloxane was the only coating capable of efficient storage on the tray for up to 24 h after field sampling without suffering significant loss of analytes (≤10% for benzene, toluene, ethylbenzene, o-xylene, decane, and limonene). Additionally, the system capability for high-throughput analysis was demonstrated by the unattended desorption of multiple fibers after on-site sampling of toluene, indoor air levels, in a polymer synthesis lab.
