Roburin A is a tannin found in oak wood ( Quercus robur and Quercus petraea [1] or Quercus alba [2]) or oak cork ( Quercus suber [3]).
It is a dimeric compound, composed of two vescalagin subunits probably linked through an ether bond between the diphenoyl group ( hexahydroxydiphenic acid or HHDP) of one subunit and the triphenoyl moiety ( nonahydroxytriphenic acid) of the other one. [4]
