摘要：

Schinus terebinthifolia is a species native to different ecoregions in the Brazilian Atlantic Forest. The plant is listed on the National Relation of Medicinal Plants and recommended as phytomedicine, however while extractive exploitation prevails as the main route of raw material a significant variation of compounds will be detected. To assure the expansion of productive chain it is important to start by studying population diversity and chemical variations. We used SSR markers for studies of genetic structure among populations from dense ombrophilous forest (ES); the deciduous seasonal forest (SM); the savanna (DOU) and the sandbanks (ITA and MSP), and compared the results to their chemical profiles of essential oil. Genetic structure revealed differences among populations and significant fixation rates. Pairwise studies and Bayesian analysis showed similarities between ITA and SM and between DOU and MSP, proving that the patterns of distribution for the species do not follow the isolation by distance or similarity by environmental conditions. The comparison between PCA of genotypes and chemodiversity reinforces the unique profile for each population despite the environmental similarity observed and genetic analysis. The most divergent genotype and chemical group was found at the ombrophilous forest, strong evidence that we should undertake conservation efforts to prevent losses of biodiversity in that area.
