The structural variation of isoprenylated flavonoids, including the ch
alcones, flavones and flavonols, as well as their dihydro derivatives
are reviewed. Emphasis is mainly directed to the modification of the s
ide attachments arising from C-5, C-10, or C-15 groups, and the freque
ncy of their occurrence among the different classes of flavonoids. Som
e aspects related to their biosynthesis and enzymology, as well as the
ir biological/pharmacological activities are also discussed. The natur
al occurrences of the various classes of isoprenylated flavonoids are
tabulated as part of this review. Copyright (C) 1996 Elsevier Science
