Zusammenfassung:The structures of cinncassiol D1 (1), cinncassiol D1 glucoside (2), cinncassiol D2 (3), cinncassiol D2 glucoside (4) and cinncassiol D3 (5), isolated from the fraction exhibiting anti-complement activity of the water extractive of Cinnamomi Cortex ("Toko Keihi"), have been characterized by means of chemical, spectral and X-ray analyses. They are novel pentacyclic diterpenes with a new skeleton.
