I am working on organbath instrument. i am facing problem in dissolving quercetin. Although i have dissolved it in dmso 100% but when aliquot lower concentration in PBS with pH 7.8 after sometime it starts precipitating. so i am not sure whether it is effective after adding to organbath or not.
I am experiencing problems with Quercetin too. It is soluble in dmso:water 1:4 (1mg/ml) which is not useful to me, because I cannot use DMSO higher than 5%. I'm trying to experiment with Quercetin sodium or disodium, (pKas can be found literature, I had troubles finding their solubility so I am working on this right now).
i have solved this problem of quercetin. if you are using pure quercetin. then you can dissolve it in 60% DMSO and then decreasing concentration further, wht i have done i have reduced concentration of DMSO to 1 %, then. for final experiment. If you need help of my calculations Do ask i will help.
