  1. Tested compounds were a mixture (1:3) of stigmasterol and β-sitosterol (1 + 2); euphol (3); sitosterol-O-β- D -xylopyranoside (4); 3,3′,4′-tri-O-methylellagic acid (5); mixture 1:1 of afzelin and quercetin-3-O-β-D-xylopyranoside (6 + 7); 3,3′,4′-tri-O-methylellagic acid 4-O-β-D-glucopyranoside (8); ellagic acid-4-O-β-xylopyranoside-3,3′,4′-trimethyl ether (9). No MBC was detected at 256 μg/mL for all compounds; MIC values were >256 μg/mL for 1 + 2, 4 and 9
