Dihydrostilbenoid
Dihydrostilbenoids (bibenzyls) are natural phenols formed from the dihydrostilbene (bibenzyl) backbone.
Examples
Dihydro-resveratrol is a natural phenol with a bibenzyl structure found in wine.[1] It is also a metabolite of trans-resveratrol formed in the intestine by the hydrogenation of the double bond by microflora.[2]
Combretastatin and combretastatin B-1 are two dihydrostilbenoids found in Combretum caffrum, an African tree.
Isonotholaenic acid is another dihydrostilbenoid found in the Andean fern Argyrochosma nivea.[3]
Bibenzyls (3,4'-dihydroxy-5,5'-dimethoxybibenzyl, 3,3'-dihydroxy-5-methoxybibenzyl (batatasin III)) can be found in the orchid Bulbophyllum vaginatum.[4]
Bis(bibenzyls)[5] and macrocyclic bis(benzyls)[6] can be found in bryophytes, such as the compounds plagiochin E, 13,13'-O-isoproylidenericcardin D, riccardin H, marchantin E, neomarchantin A, marchantin A and marchantin B in the Chinese liverwort Marchantia polymorpha.[7] Prenylated bibenzyls can be isolated from the New Zealand liverwort Marsupidium epiphytum[8] or from Radula kojana.[9]
One unique class of stilbenoid derivative was first isolated from Scorzonera humilis. They were named the tyrolobibenzyls after Tyrol in the eastern Alps, where the plant was collected.[10]
