Table 15.9 also presents the newly reported dihydroflavonols with prenyl, geranyl, and lavandulyl side chains (compounds 353-368), which have been mainly found in species of the family Leguminosae. For example, the root bark of Dioclea grandiflora has been the source of three new prenylated dihydroflavonols, dioclenol (353), " floranol (355), " " and paraibanol (358). Paraibanol is the 8-prenyl derivative of the dihydroflavonol diosalol (3,5,7,2, 5 -pentahydroxy-6-methoxyflavanone, 339), which was isolated from the same plant. Other newly reported prenylated dihydroflavonols from this family include the monoprenylated flavanones 356 from Rhynchosia densiflora and scariosin (357) from...

Three additional lectins, obtained from Canavalia brasiliensis (ConBr), Dioclea violacea (DVioL), and Dioclea grandiflora (DGL), have all been found to stimulate T-cell activation and apoptosis in vivo, but they also produce important side effects, including inflammation associated with high endothelial venule necrosis [187].
