Abstract Three novel cyclicamides, clausenamide, neoclausenamide and cycloclausenamide, that lower elevated blood SGPT levels have been isolated front the leaves of Clausena lansium. By means of spectrometric data combined with chemical reactions, their structures have been elucidated. The proposed structures of clausenamide and cycloclausenamide were further confirmed by X-ray crystallographic analysis
