Artocarpus

Isoprenoid-substituted flavonoids from Artocarpus (Moraceae) plants 98H(47)1179.

This section comprises a series of flavones, mostly reported from genera of the Moraceae (Morns, Dorstenia, Artocarpus) and the Fabaceae (Derris, Tephrosia, Euchrestd). Very few reports exist on Vancouveria and Epimedium (Berberidaceae). In contrast to most of the other... 

Generally, cyclization between 7-OH and C-8 occurs in various flavone derivatives of Artocarpus (e.g., artonol D artocommunol CA, artelastofuran Figure 12.6.). However, A. rigida yielded both 7, 6- and 7, 8-cyclized compounds (artonin M, P compounds 250 and 259, Table 12.3). In this section, compounds with pyranosubstitution at both ring A and B are listed, for example, artonol D (Figure 12.6). All of these compounds appear to be mainly accumulated in rather lignified parts of the plant, such as heartwood, bark, and shoot. It is hardly perceivable that such complex compounds could occur in exudates of aerial parts.
