Two alkaloids, furomegistine I (1) and furomegistine II (2). were isolated from the bark of Sarcomelicope megistophylla. Their structures have been elucidated on the basis of MS and NMR data. Both belong to the category of furanopyridine alkaloids and should be considered as oxidation products of a furo[2.3-b]quinoline precursor. The two alkaloids exhibited moderate cytotoxic activity.
