Table 16.2 lists more than 80 examples of new isoprenylated chalcones reported in the period 1992 to 2003 (see also Figure 16.7). Almost half of the compounds described here are from the Leguminosae, a trend that is also evident in earlier surveys. Other plant families that are well represented in Table 16.2 are the Moraceae and the Cannabinaceae. The literature on isoprenylated flavonoids in general has been reviewed by Barron and Ibrahim to the end of 1994 57 jjjg phenolic constituents of Glycyrrhiza species (licorice), among which are many isoprenylated chalcones, were the subject of an extensive review that includes literature published up to the end of 1996. Nomura and Hano have reviewed the literature on isoprenylated phenolic compounds of the Moraceae to the end of 1993. More recent descriptions of isoprenylated flavonoids are available for the hop plant, Humulus lupulus (Cannabinaceae),and the Moraceae genera Artocarpus and Dorstenia. ...
