I want to interpritonealy inject resveratrol (10-15 mg/kg) in rats. In most experimental studies resveratrol dissolved in different vehicles such as: ethanol, saline, ethanol+saline, water (pH:6), propylene glycol, glycerol formal and ...
but, the liquid forms often use excipients known to have a recognized action or effect (i.e. ethanol and propylene glycol). Moreover, the solubility of resveratrol in these solvents are far from optimized.
Any help would be much appreciated.

Thanks all,
I will prepare stock solution as follow;
100 mg resveratrol + 2ML ethanol (200 un/2000uL)
afterward for a rat (i.e. 200 g wight- 10mg/kg resveratrol) i need 2mg resveratrol (40 uL of stock solution) . If i dilute the volume (40 uL) into 460 uL of distilled water or saline the final percentage of organic solvent (ethanol) will be 8.69 %!!! I can not inject more than 500 uL volume for each rat.
what is your opinion?
Dont worry dear Jesus!
I did not treat rats with the mentioned doses!
if I need to prepare 12.5 mg resveratrol / kg body weight what can I do ?
50 mg of Resveratrol (powder) can be dissolved in 1 ml absolute ethanol.
Keep it in freezing temperature at dark condition for one month (stock solution).
