Abstract Fatty acids (FAs) and volatile organic compounds (VOCs) are among bioactive substances produced by macroalgae, which have important reported biological activities. The aim of this work was to determine the diversity of FAs and VOCs in brown, green, and red Antarctic macroalgae. Results showed that seaweeds contained 13 to 25 FAs with a predominance of palmitic, oleic, linoleic, and eicosapentaenoic acids. Concerning VOCs, 28 to 55 distinct compounds could be detected, distributed among aldehydes, hydrocarbons, furan derivatives, and ketones, for instance. Generally, hexanal (5.83%–25.51%), heptadecane (0.92%–49.84%) and 2-pentylfuran (3.02%–12.57%) were found in considerable amounts in the analyzed specimens. It is worth noting that, to the best of our knowledge, this was the first time that Antarctic macroalgae had their VOCs elucidated. Therefore, Antarctic seaweeds were composed of several VOCs and FAs which could assist in the elucidation of secondary metabolites from these organisms. Keywords Fatty acids .

Introduction Seaweeds comprise a diverse group of approximately 10,000 aquatic organisms that can be divided depending on their pigmentation and biochemical and morphological aspects into three main groups that include the Rhodophyta, Ochrophyta, and Chlorophyta (Rodrigues et al. 2015; dos Santos et al. 2019). The biological potential of macroalgae has led to the use of seaweeds as food, fertilizers, bioenergy resources, and additives in cosmetics, for instance, mainly in Asiatic countries (Hamid et al. 2015; Passos et al. 2020). Despite their high potential, macroalgae can still be considered largely Electronic supplementary material The online version of this article (https://doi.org/10.1007/s10811-020-02170-9) contains supplementary material, which is available to authorized users. * Claudio Martin Pereira de Pereira [email protected] 1

unexplored as less than 5% of the known species have been used commercially, making them feasible sources of novel biological applications (Andrade et al. 2013; Rodrigues et al. 2015). The high adaptive capacity of seaweeds to the most adverse environments enabled their survival in severe habitats that include Polar, sub-Antarctic, and Antarctic regions of the planet (Graeve et al. 2002; Becker et al. 2010).
