title: Carbazole alkaloid with antimicrobial activity from Clausena heptaphylla.
abstract: A new carbazole alkaloid designated as clausenal was isolated from the leaves of Clausena heptaphylla and its structure established as 1,8-dimethoxy-3-formylcarbazole from physical, chemical and synthetic evidence. The alkaloid was found to be active against both Gram-positive and Gram-negative bacteria, and fungi.
