Impact of seasonal variations on the carotenoid and chlorophyll content of Fucus virsoides from the Adriatic sea

Marine macroalgae are valuable sources of bioactive compounds which are used in nutritional and/or pharmaceutical products. Marine algae can be classified based on pigment contents which have various biological activities such as antioxidant and anti-inflammatory activities (Catarino et al., 2018). Widely distributed Fucus genus of brown macroalgae is an excellent source of fucoxanthin carotenoid which contributing around 10% estimated total production of carotenoids in nature (Kim and Pangestuti, 2011). Chlorophyll a, is the most important chlorophyll for photosynthesis since allow the conversion of light into biological energy (Osorio et al., 2020). The inherent characteristics of each species and different environmental factors induced by seasonal variations in their normal ecosystem (temperature, light, salinity) controls the macroalgal growth rate in nature and may also affect their pigment contents (Marinho-Soriano 2012). However, the potential impact of seasonal variations in their bioactivity profile is often neglected in analytical studies. The brown alga Fucus virsoides is an endemic species in the Adriatic Sea and its typical habitat is in the intertidal zone, an extremely variable environment (Najdek et al., 2014). Therefore, the aim of this study was to evaluate the effect of seasonal environmental variations on pigment content of Fucus virsoides from the Adriatic Sea.
