| Study 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 |
| Study Type | Chemcial profile of the volatiles from plants of the Atlantic Rainforest in São Paulo |
| Study Summary | Native plants were sampled from nine Atlantic rainforest locations in Brazil for botanical identification, herbarium mounts and chemical analyses. Plants were marked and the coordinate reference determined by Global Positioning System (GPS). Botanical names are as presented in the list of species of Brazilian flora (Lista de Espécies da Flora do Brasil, Jardim Botânico do Rio de Janeiro, 2015). Voucher specimens were deposited at the Herbarium of Instituto Agronômico de Campinas (IAC) (http://herbario.iac.sp.gov.br/), under the given accession numbers (Table 1). Marked plants were resampled in two subsequent years and those failing to be located or in poor condition were excluded from analyses. Environmental data were obtained from meteorological stations at the locations. Monthly values were used to calculate the average seasonal data. |

| 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. |
