From the trunk bark of Fagaropsis glabra Capuron (Rutaceae, tribe Toddaliaeae, subtribe Phellodendronnae) (1,2), a very rare tree unknown in traditional medicine in Madagascar, we have identified four alkaloids of the benzophenanthridine group: acetonyl 8-dihydrochelerythrine, norchelerythrine, chelerythrine, and dihydrochelerythrine, as well as candicine, a phenolic alkaloid.The isolation of benzophenanthridine alkaloids from F. glabra is in support of the previous reports of abundant occurrence of these alkaloids in the Madagascar (3,4) and South African (5,6) rutaceous plants.Although F. glabra has an appearance similar to Fagaropsis angolensis Engler (l), the differences noticed in their alkaloidal profiles, especially the lack ofchelerythrine in F. angolensis (5), seems to confirm that we have two distinct species.
