From the ether extract of the seeds of Clausena lansium, three new amide derivatives have been isolated, and their structures elucidated by chemical and spectroscopic methods. They were shown to be N-cis-styryl-cinnamamide, N-methyl-N -cis-styryl-cinnamamide and N -methyl-N -phenethyl-cinnamamide, which we have named lansiumamides A, B and C, respectively. In addition, a known amide, lansamide-1 was identified. |
