Oligostilbenoid
Oligostilbenoids (oligo- or polystilbenes) are oligomeric forms of stilbenoids. Some molecules are large enough to be considered polyphenols and constitute a class of tannins.[1]
Chemical structure of hopeaphenol.

- cajyphenol B[3]
- Flexuosol A[5]
- Hemsleyanol D[2]
- Hopeaphenol[4]
