The range of natural dimeric A-typeproanthocyanidins is extended by identification of two new dimeric afzelechins in the form of 7-OMe-epiafzelechin-(4 beta-->8,2 beta-->0-->7)- epiafzelechin and 7-OMe-epiafzelechin-(4 beta-->8, 2 beta-->0-->7)-ent-afzelechin. These are accompanied in the stem bark of Cassipoureagummiflua by the relatedmetabolites afzelechin, kaempferol-3-0-alpha-L-rhamnopyranoside
