Uvaria macrophylla

Six new flavanones having one or more C-benzyl groups attached to C-6 or C-8, or both, have been reported from members of the Annonaceae, a family from which many C-benzylated flavanones and dihydrochalcones had previously been described. The new compounds (212-217) are presented in Table 15.6. Macrophyllol (212) and macrophyllol A (213, Figure 15.6) have been isolated from the roots of Uvaria macrophylla. These consist of 5-hydroxy-6,7-dimethoxyflavanone with one 2-hydroxy-5-methoxybenzyl unit attached to C-8 and C-6, respectively. The roots of Xylopia africana yielded isouvarinol (214, Figure 15.6), in which one 2-hydroxybenzyl unit is attached to C-6 and two units to C-8. Its...
