Bioautographic assay of Ci_SFEopt and Ci_SFEpur developed in 85:15 (v/v) dichloromethane:methanol as the solvent. (A) Antibacterial activity against Staphylococcus aureus (oral isolate), S. aureus ATCC (left); and Pseudomonas aeruginosa (right). (B) Antifungal activity against Candida albicans (left) and C. krusei (right). Spots on different Rf values: 1. Rf = 0.18 (activity only against S. aureus ATCC); 2. Rf = 0.20 (activity only against P. aeruginosa); 3. Rf = 0.65 (activity against S. aureus ATCC and C. albicans); 4. Rf = 0.71 (activity against all tested bacteria and fungi); 5. Rf = 0.76 (activity against all tested bacteria and fungi, except C. krusei); 6. Rf = 0.82 (activity against all tested microorganisms, except P. aeruginosa and C. krusei); 7. Rf = 0.88 (activity against all tested bacteria and fungi, except C. krusei).
