Bioactive compounds in S. ramosissima fractions. TPC: total phenolic compounds [mg GAE/g DM] (p < 0.001), TFC: total flavonoids [mg QE/g DM] (p = 0.240), TCT: total condensed tannins [mg CE/g DM], TAC: total anthocyanidins [mg CCE/g DM] (p < 0.001), CHL: total chlorophyll [µg/g DM] (p < 0.001), TCA: total carotenoids [µg/g DM] (p < 0.001), n.d.: not detected or concentration lower than the limit of detection, n/a: not available. Results are expressed as mean values with standard deviations (in brackets). Different letters denote significantly different results, calculated individually for each compound group.
