Grape leaves

Hi everyone.

I wanted to thank you for helping me with answers regarding tinctures.

I do have one more.

I have wild grape vines growing along side of a fence. It doesn't fruit at all. Does it still contain resveratrol?

thx in advance

I don't know, but your local extension service might have the answer... I called mine once with a question about using wild cherry leaves (for crisper pickles), and there was some big database that they could check for all the chemical compounds present in a plant...
