Examination of the root wood of Formosan Toddalia asiatica led to the isolation of four N-cyclohexylamides: N,N'-dicyclohexyloxamide, N,N'- dicyclohexylurea, toddaliamide, methyltoddaliamide; one dimeric coumarin; toddasiatin; and six alkaloids: skimmianine, norchelerythrine, oxyavicine, avicine, oxynitidine and nitidine, from the tertiary non-phenolic basic fraction. Toddaliamide, methyltoddaliamide and toddasiatin are new compounds while N,N'-dicyclohexyloxamide and N,N'-dicyclohexylurea were isolated for the first time from nature. The structures of all the compounds were elucidated by spectral data and chemical evidence.
