Title: Three new carbazole alkaloids from Murraya euchrestifolia.
Abstract: The structures of a monomeric carbazole, isomurrayafoline-B (1), and two new dimeric carbazoles, bismurrayafolinol (3) and oxydimurrayafoline (9), from Murraya euchrestifolia Hayata (Rutaceae) have been studied in spectral and chemical experiments.
