Reproducibility challenges in the search for antibacterial compounds from nature
Fig 2
a. An overlay of UV chromatograms of acetone (blue) and DMSO (red) based working solutions of a methanol leaves extract of G. tinctoria, which had better solubility in acetone. Higher quantities of phytochemicals are observed in the acetone based working solution towards a less polar region of the chromatogram. b. Comparison of base peak chromatograms of acetone (blue) and DMSO (red) based working solutions of a methanol leaves extract of G. tinctoria, which had a better solubility in acetone. At least three additional compounds (marked A) are visible in the less polar region of acetone based working solution’s chromatogram.
