“…Classical chromatographic techniques, classified as planar on paper (PC), thin layer (TLC) and liquid on column (LC) can use cellulose paper or silica gel as stationary phases, polar and apolar solvents as mobile phase, and several revealing compounds, among them iodine, ferric chloride, sulfuric vanillin, 2,4-dinitrophenylhydrazine (2,4-DNFH), and ultraviolet light (UV) in short and long wavelengths, these techniques cover the analysis a Development, v. 9, n. 8, e454985979, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i8.5979 wide range of compounds.

The study of chromatographic techniques, classical and modern, describes the simplicity and, at the same time, the advances that this area has undergone in recent years in quality scientific research and also in learning in undergraduate and postgraduate courses around the world. This paper investigate a characterization by thin layer chromatography (TLC) and gas chromatography coupled with mass spectrometry (GC-MS), as a method developed by graduate students that involve a combination of a classic and modern technique, as well as results about the physicochemical properties of the essential oil of Bauhinia monandra flower. Essential oil was extracted by Clevenger, the TLC was performed in different eluents and developers, and thus the retention factors (Rfs), and the chemical profile by GC-MS were obtained. The essential oil of the flowers showed a yield of 0.06%, positive solubility in ethanol 70%, refractive index of 1.3621, optical rotation of +36.4αD and relative density of 0.941 g mL-1 at 20 °C. In the TLC analysis 18 Rfs were observed after the use of different developers, with the predominant class of oxygenates compounds. In the GC-MS analysis, 7 compounds were observed, being two majorities, characterized as panaxene with 20.51% and the α-guaiene with 33.39%. The essential oil of B. monandra flower showed a predominance of 70.22% of sesquiterpenic compounds. The allied techniques, classic and modern, demonstrated different ways of evaluating the essential oil through its chemical composition, both techniques showed high efficiency and precision, in addition was an appropriate project developed by postgraduate students.

“…If confirmed, the allelopathic effects of 1 would become a major conservation issue, especially toward seagrass communities that are considered the most productive and complex marine ecosystems in the Mediterranean [14]. However, in addition to C. cylindracea, compound 1 has been isolated from other Caulerpa species, including Caulerpa prolifera that is endemic of the Mediterranean [15], and it has been shown to be the most abundant metabolite of the highly invasive C. taxifolia [16]. However, differently from C. taxifolia and C. prolifera, C. cylindracea features a drastic decrease of its biomass in winter that could led to the caulerpenyne accumulation in the substrate leading to suppression of possible competitors [13].…”

Among the factors affecting community dynamics, bioactive natural products act as mediators of key biological processes, including competition, predation, defense, and reproduction. Their chemical diversity thus critically contributes to the stability of ecological systems. Accordingly, research in chemical ecology provides useful information for a better understanding of ecosystem functioning and biodiversity. On the other hand, the potential of bioactive molecules produced by invasive species to become disruptive to native communities has been recently emphasized in the literature, raising novel and urgent questions about the interactions of invasive metabolites with macromolecular counterparts of ecological and ecotoxicological interest. Relevant issues strongly emerged in the Mediterranean Sea where the green alga Caulerpa cylindracea and the seagrass Halophila stipulacea, both exotic macrophytes containing peculiar bioactive compounds, have become invasive. In particular, the study of these two species has led to the production of a recent literature focusing on "alien biomolecules" and their potential impact on the native community. The present article summarizes the obtained results by giving special emphasis to the urgent need for individuating molecular interactions that are likely to exert cascade effects at all levels of biological organization, from molecules to ecosystems.
