Detection of the inhibition of growth of C. nicotianae (cm) and M. phaseolina (cm) (A-1 and B-1, respectively). 7, pinolidoxin; 8, O,O′-diacetylderivate; 9, epi-pinolidoxin; 10, stagonolide C; 11, modiolide A; 12, stagonolide H; and 1, truncatenolide. All compounds were tested at a final concentration of 2.5 × 10^–3 mol/L. The experiment was performed in triplicate with three independent trials. Data are presented as means ± the standard deviation (n = 4) compared to the control with a p-value < 0.001.
