Prenylindole alkaloids from Raputia praetermissa (Rutaceae) and their chemosystematic significance

The dichloromethane extract from the stems of Raputia praetermissa afforded four new compounds, 4-deoxyraputindole C (1), raputimonoindoleA-B (2, 3), and hexadecanyl 2-hydroxy-4-methoxy-cinnamate (5), besides the alkaloids 5-(4-methoxymethylfuran-2-yl)-1H-indole (raputimonoindole C), furoquinolines maculosidine, robustine, evolitrine and dictamnine. The hexane extract yielded N-methyl-4-methoxyquinolin-2(1H)-one, skimmianine, cycloartenone, sitosterol, stigmasterol and sitostenone. The anthranilate alkaloid content indicates that the genus is strongly related to those included in Cusparieae tribe, but differs from Neoraputia by the absence of prenylindole alkaloids in the late, whose species have previously been placed in Raputia.
