The petroleum ether (PE, 30–60 °C) and ethyl acetate (EA) fractions extracted from strains 4WBY1 (1 and 6), 6WBY3 (2 and 7), 7WBY2 (3 and 8), WBS019 (4 and 9) and WBS020 (5 and 10). These fractions were developed in a preselected solvent system containing trichloromethane/toluene/ethanol/formic acid (4:4:0.5:0.1, by volume) and visualised using several methods, namely, ultraviolet lamps at 365 nm (A), heating for 3 min at 105 °C after spraying with vanillin sulphuric acid (B), ultraviolet lamps emitting at 365 nm after spraying with 2% aluminium chloride solution (C) and 0.04 mg·mL−1 DPPH in ethanol (D).
