| Project Title: | Bioprospection of the aromatic potential of species from the Atlantic Rainforest in São Paulo: occurrence, taxonomy and chemical, genetic and physiological characterization of plant populations |
| Project Type: | Atlantic Rainforest Chemical Characterization |
| Project Summary: | Neotropical Atlantic Rainforest is a plant diversity rich biome and encompasses distinct vegetation formations depending on the environment. Essential oils (EOs) are part of the plants volatilome and consist of complex blends of hydrophobic metabolites. EOs are valuable for green chemistry applications. However, the interactions between the environment and plant processes controlling its chemical composition are poorly understood. The work aimed to provide a comprehensive characterization of the EOs from native species in distinct Atlantic Rainforest formations and access their antimicrobial potential. Aerial parts were harvested and dried for oil extraction by hydrodistillation, in two subsequent years. Chemical profiles were done by GC-MS and the metabolites identified by mass spectra and retention indices. Oil contents were determined by area normalization using GC–FID. Antimicrobial activity was investigated by in vitro growth inhibition. Computing and graphics were generated in R. The EO chemical profile was determined for plants from 50 species, in 15 botanical families, from nine Rainforest locations. Mono and sesquiterpenes were the most abundant chemical classes, followed by methyl ketones, phenylpropanoids and benzyl alcohols. Season and location were better discriminants for EO chemical profile than botanical family. Modules of co-regulated metabolites were identified and shown to correlate with environmental factors. Antimicrobial activity was widespread for the isolated EOs. Results provide a comprehensive metabolite profile of the EOs from the Atlantic Rainforest. Metabolite modules, correlated to environmental conditions, are conserved in complex plant populations. EOs are effective to inhibit pathogenic bacterial and fungal growth. |
