Phytochemical investigation of barks of Christiana africanaled to the identification of cyclopeptide alkaloids, flavonoids, coumarinolignans, iridoids, sesquiterpenoids, and triterpenes. This plant was classified so far in the Tiliaceae family. This study was started while the genomic study of numerous specimens was described in order to establish new criteria for Malvales botanical classification. In the present work, twenty components were identified, belonging to the three major classes of secondary metabolites: alkaloids, phenols, and terpenes. In the first class, cyclopeptides are wellknown compounds in Rhamnaceae and Sterculiaceae. Their presence in Malvaceae in APG2 sensus suggests a possible chemical link between the exTiliaceae and the Malvaceae. [ABSTRACT FROM AUTHOR]
