Four new carbazole alkaloids, clausines A, C, G and J were identified as 3-formyl-2-hydroxy-8-methoxycarbazole 3-carbomethoxy-7-methoxycarbazole, 3- carbomethoxy-1-hydroxy-6-methoxycarbazole and 3-formyl-1, 7-dihydroxy-6- methoxycarbazole, respectively, from a methanol extract of the stem bark of Clausena excavata.
