چکیده

Background: trans-resveratrol (t-res) is a natural phenolic compound with various biological activities such as antioxidant,anticancer,cancer chemopreventive,cardioprotective,and neuroprotective. objectives: there is no comprehensive study about the stability of t-res in human plasma. with respect to extensive use of t-res in clinical trials and pharmacokinetic studies,in this study,we aimed to measure the plasma stability of t-res at different conditions of lighting,ph,and temperature,and in the presence of routine antioxidant agents (bht and vit c). materials and methods: t-res stability in human plasma was evaluated at different conditions of lighting,ph and temperature,and in the presence of routine antioxidant agents (bht and vit c),and quantitatively determined using hplc-uv method at 306 nm. results: our findings revealed that t-res was quite stable in different temperatures ranging from-70 °c to 25 °c,and acidic ph conditions in plasma for a month,when protected from light,but it was unstable in alkali ph and in lighting conditions. conclusions: in lighting conditions,most of t-res was isomerized to the other isomer cis-resveratrol. t-res is unstable in alkali ph and when exposed to light. t-res was quite stable at other conditions,and several freeze-thaw cycles did not have any effect on its stability.
