WebMay 1, 2024 · Stilbenes are some of the important phenolic compounds originating from plant families like Vitaceae Gnetaceae, and Dipterocarpaceae. Structurally, they have a C6–C2–C6 skeleton, usually with two isomeric forms. Stilbenoids are hydroxylated derivatives of stilbene and have a C6–C2–C6 structure. They belong to the family of phenylpropanoids and share most of their biosynthesis pathway with chalcones. Under UV irradiation, stilbene and its derivatives undergo intramolecular cyclization, called stilbene photocyclization to form dihydrophenanthrenes. Oligomeric forms are known as oligostilbenoids.
