Figure Lengend Snippet: Dose-response curves of 24-hour of F. deltoidea , G. procumbens and O. stamineus extracts against S. aureus and MRSA. S. aureus and MRSA were seeded at density standardised to 0.5 McFarland standard (1 × 10 8 CFU/mL). The pathogenic bacteria were being treated with (A) F. deltoidea , (B) G. procumbens , (C) O. stamineus extracts, (D) positive and (E) vehicle controls. The plates were incubated at 37 °C for 24 h after which the MTT assay was performed. Each point represents mean ± SD of quadruplicates.

Figure Lengend Snippet: Antiproliferative effects of the extracts of (A) O. stamineus , (B) G. procumbens and (C) F. deltoidea on three human cancer cell lines at 24 h and 48 h. Cells were treated with various concentrations (50, 125, 250, 500, 750, 1000 µg/mL) of methanol, ethyl acetate, chloroform and butanol extracts. Cell proliferation was measured at 24 h and 48 h by MTT assay. The data were expressed as mean ± SD deviation values obtained from three independent determinations. *, P < 0.05 versus controls.
