Resumo

Asteraceae is one of the most abundant families in Brazilian Campos (grasslands) and Cerrado (savanna). Several Asteraceae species are able to resprout owing to the development of bud-banks in the rhizophores, xylopodia, soboles, and gemmiferous roots. The bud-bearing and thickened underground organs of some Aldama species tend to become odoriferous and produce compounds having biological activities. This study aimed to evaluate the morphoanatomy of the underground organs and to describe the chemical profile of the essential oils produced by them. The belowground organs of four Aldama species were prepared using standard histological techniques. Essential oils were obtained by hydrodistillation, and their components were identified using gas chromatography-mass spectrometry. Some morphological aspects of the underground stems were peculiar for the species investigated, such as the development of extensions and storage of inulin-type fructans, whereas some differed from the traits reported for the genus. The chemical profile of the essential oils differed among the four species analyzed, and only a-carene and limonene were the common constituents. Sixteen compounds had the potential to be considered as chemicalmarkers. The underground organs are related to the adaptation of these plants to withstand unfavorable climate conditions characteristic of their habitats. (C) 2017 SAAB. Published by Elsevier B.V.
