A new phenolic furoquinoline alkaloid, evomerrine, was isolated from the leaves of Melicope semecarpifolia. Its structure was elucidated from spectral data and chemical evidence. Six other known furoquinoline alkaloids, platydesmine, skimmianine, kokusaginine, haplopine, heliparvifoline and confusameline, along with one flavonoid, ayanin, were also isolated. © 1995.
