  1. aN = 3 replicates; MIC/MBC concentrations reflect mean values across trials. Abbreviations: N/A (not applicable); BC (bactericidal); NI (no inhibition by solvents at the lowest dilution [1:10]). Efficacious compounds with a measureable inhibitory concentration or bactericidal activity are bolded.
  2. bColumns marked N/A or BC indicate that MBCs could not be determined due to lack of inhibition (N/A) or bactericidal activity (BC).
  3. cConcentration reflects total alkaloid content.
