Semi-quantitative evaluation of solubility of crude extracts in 10% DMSO and acetone.
Fig 1.
An overlay of UV chromatograms of acetone (blue) and DMSO (red) based working solutions of an n-hexane rhizomes extract of C. longa.
Qualitative similarity and higher quantities of phytochemicals observed in the acetone based working solution, which had better solubility compared to that of DMSO.
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.

a. An overlay of UV chromatograms of acetone (blue) and DMSO (red) based working solutions of a methanol barks extract of F. carica, which had a better solubility in 10% DMSO. Higher quantities of phytochemicals are seen in the in a DMSO based working solution. b. Comparison of base peak chromatograms of acetone (blue) and DMSO (red) based working solutions of a methanol barks extract of F. carica, which had a better solubility in 10% DMSO. At least 4 (marked A) and 1 (marked B) additional compound(s) are visible in the chromatograms of acetone and DMSO based working solutions, respectively.
