Why not? Begin by using the isocratic flow conditions and adapt them for your situation.

Jack Silver

If the resveratrol is the only compound you want, it's fine to purify it isocratically. Earlier eluting compounds will come out near the void. you may need to wash the column with strong solvent periodically to avoid "ghost peaks" from earlier injections.

Thank you all

why not !!, but first of all method should be established and optimised

Be carefull to protect it from sunlight - its pretty unstable. More - it can get absorbed on plastic surfaces.
