  1. 1,2,3compounds with the same superscript are likely to be the same compound, after comparison with the reference TLC plate sprayed with vanillin-sulphuric acid.
  2. 4 - = active compound not present, √ = active compound present.
  3. a E. coli = Escherichia coli, E. faecalis = Enterococcus faecalis, S. aureus = Staphylococcus aureus, C. albicans = Candida albicans, C. neoformans = Cryptococcus neoformans.
  4. bExtracts: 1 = diethyl ether extract, 2 = DCM/MeOH extract, 3 = EtOAc extract, 4 = EtOH extract, 5 = H2O extract.
