SyMiC: A novel methodology for the location and exploitation of "economically important metabolites" of wild plants bearing glandular trichomes.

Glandular trichome types of certain plant families, an additional taxonomical marker in plant taxonomy, produce secondary metabolites, which play fundamental roles in ecosystem interaction as well as biomedical research, agriculture and chemical industries. Given their importance and the necessity of time economy, the first step in the processes of natural plant products exploitation, may be the ability to pre-select plants with prospective interest among a plethora of them.
This led us to introduce a methodology for revealing "economically important metabolites" produced by glandular trichomes of wild plants. The methodology was named SyMiC (Sy-Systematic, Mi-Microscopy, C-Chemistry) after the three following steps; pre-selection of valuable taxa, based on data derived from Herbarium specimens, tracing of their glands’ isolated secretory products and selection of the most suitable isolation method for essential oils according to the second step results and the purpose of their exploitation. The methodology has been applied mainly in Lamiaceae, on the genera Thymus (65 taxa), Mentha (149 taxa), Origanum (155 taxa), Salvia (220 taxa) and Micromeria (20 taxa) and has revealed their most prosperous taxa, concerning yield and chemical composition of their essential oils.
The main research’s conclusions concern the reliability and importance of data derived from dried botanical specimens, the importance of glandular trichomes as the main essential oil resources and the correlation between glandular trichome types and the exploitation of their products.
The main advantages of the proposed methodology are that SyMiC is accurate, simple enough to be followed by a wide range of scientists, relatively fast and of low cost. Hence, we believe it constitutes a useful tool for locating worldwide valuable taxa and moreover reveals new possibilities of cultivation and further exploitation of those wild plants, some of which have yet unknown attributes and uses of considerable biotechnological and economical interest.
