What other solvent than DMSO and Water can I use to dissolve an aqueous extract (lyophilized extract) to evaluate the antimicrobial activity?

31 August 2023 0 3K Report

My extract is not easy to dissolve. For example, I need a stock concentration of 500 mg/ml. I have used DMSO but I can only dissolve for 250mg/ml(thick or viscous) and in water at 125mg/ml(it is very thick or viscous). The extract is very voluminous and light that it absorbs all the liquid and if I add more solvent the concentration is reduced.
