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]

Examples

Dimers
  • Ampelopsin A[2]
  • Epsilon-viniferin
  • Pallidol[3]
  • Quadrangularin A[3]

Trimers
  • α-Viniferin
  • Ampelopsin E[2]
  • trans-Diptoindonesin B
  • Gnetin H[4]

Tetramers
  • cajyphenol A[3]
  • cajyphenol B[3]
  • Flexuosol A[5]
  • Hemsleyanol D[2]
  • Hopeaphenol[4]
  • Vaticanol B[2]
  • R2-Viniferin (syn. Vitisin A)

Modified
  • Diptoindonesin C can be isolated from the bark of Shorea pinanga[4]

Other
  • Diptoindonesin F can be isolated from the bark of Shorea gibbosa[2]

Glycosides
  • Diptoindonesin A
