STRUCTURES OF MURRAYASTINE, MURRAYALINE, AND PYRAYAFOLINE; THREE NEW CARBAZOLE ALKALOIDS FROM MURRAYA EUCHRESTIFOLIA

The structures of murrayastine (1___∼), murrayaline (2___∼), and pyrayafoline (3___∼), new carbazole alkaloids from Murraya euchrestifolia Hayata(Rutaceae) collected in Taiwan, have been determined by spectral and synthesis experiments.
