The correlation between DPPH scavenging activity (expressed as IC₅₀) and TPC and TFC in F. distichus collected in different Arctic seas: experimental data—markers (error bars for SD at n = 3), and the correlation—lines (blue—TPC; red—TFC). BfS (Baffin Sea)–St. 1 (Disko Bay), (NS) Norwegian Sea–St. 2 (Ringvassøya Island), WS (White Sea)–St. 3 (Pezhostrov Island), and BS (Barents Sea)–St. 4 (Korabelnaya Bay), St. 5 (Zavalishina Bay), and St. 6 (Zelenetskaya bay) (error bars for SD at n = 3). The station locations (St. 1–St. 6) are presented in Figure 1.
