Zusammenfassung:Air dried leaves and stem bark of Campylospermum mannii used in the south of Cameroon by the Baka pigmies to remedy heart and stomach disorders have been examined for their photochemical content. Three biflavonoid, amentoflavone, robustaflavone and chamaejasmin were characterized alongside with two new biflavonoids, campylospermones A and B. The structures of isolated compounds were established from complete analysis of their spectroscopic data (MS, IR, 1H and 13C NMR). These results place the Ochnaceae family among the sources of the rare class of 5-deoxyflavonoids.
