Isolation of S. coccinea bioactive compounds. (a) Hydrophobic chromatography of ethanol extract on polychrome-1 column (4.5 cm × 7 cm). 1—Hydrophilic fraction eluted with water; 2—hydrophobic fraction eluted with 40% aqueous ethanol. (b) RP-HPLC of fraction 2, obtained after the hydrophobic chromatography, on a Luna C₁₈ (10 mm × 250 mm) column in a gradient of acetonitrile with 0.1% TFA. The numbers and solid lines under the peaks indicate collected fractions. Fractions from which the peptide was isolated are gray colored.
