A systematic investigation of stilbenoids present in vine roots is being undertaken, to assess their biochemical role. Another new tetramer of resveratrol (3,5,4'-trihydroxystilbene), named r-2-viniferin, has been isolated from the roots of species and hybrids of the genus Vitis. Its structural identification is reported, showing its relation to the free phenolic r-viniferin identified earlier.
