Two pyranocarbazole alkaloids, clausine-W (1) and clausine-T (2), as well as two furocarbazole alkaloids, furoclausine-A (3) and furoclausine-B (4), were isolated and identified from the acetone extract of the root bark of Clausena excavata. Their structures have been elucidated by spectroscopoic analyses.
