  1. The results are the mean values of triplicate tests measured after 24–48 h incubation at 35 ° C; na: not active; /: not tested; agentamicin and nystatin were used as reference antibiotics for bacteria and yeasts respectively; B1: Oleic acid and n-hexadecanoid acid; B2: n-hexadecanoic acid, octadecanoic acid and docosanoic acid; 1: lupeol; 2: aurantiamide acetate.
