Two new 3-methoxy-4-quinolone alkaloids from the bark of Sarcomelicope megistophylla.
Two new alkaloids, megistonine I (1) and megistonine II (2), were isolated from the bark of Sarcomelelicope megistophylla. Their structures, which are derived from the 3-methoxy-4-quinolone basic skeleton, were elucidated on the basis of MS and extensive NMR studies.
