Volatile Profiles and DNA Barcodes of Myrtaceae Species with Occurrence in the Brazilian Amazon.

Myrtaceae family includes many species with taxonomic challenges, making it one of the most complex families to identify. This study used DNA barcoding to find molecular markers for species authentication based on the Myrtaceae family's chemical composition and genetic diversity. Essential oils and genetic material were extracted from the leaves of six different species: Eugenia uniflora, E.

Essential Oil Chemotypes and Genetic Variability of Leaf Samples Commercialized and Cultivated in the Amazon.

(Lauraceae), also known as "true cinnamon" or "Ceylon cinnamon" has been widely used in traditional folk medicine and cuisine for a long time. The systematics of presents some difficulties due to genetic variation and morphological similarity between other species. The present work aimed to find chemical and molecular markers of samples from the Amazon region of Brazil.
