Diarylheptanoid

Diarylheptanoids consist of two aromatic rings (aryl groups) joined by a seven carbons chain (heptane) and having various substituents.

A diarylheptanoid is an intermediate in the biosynthesis of phenylphenalenones in Anigozanthos preissii[2] or Wachendorfia thyrsiflora (Haemodoraceae).

[3] Cyclic diarylheptanoids formed from myricanone can be isolated from the bark of Myrica rubra (Myricaceae).

[4] Two cyclic diarylheptanoids, named ostryopsitrienol and ostryopsitriol, can be isolated from the stems of endemic Chinese medicinal plant Ostryopsis nobilis (Betulaceae).

[7] The antioxidant activity of diarylheptanoids isolated from rhizomes of Etlingera elatior (Zingiberaceae) is greater than that of α-tocopherol.
