Abstract
Studies on alkaloids of Capparis deciduas have led the isolation of four novel speridine alkaloids named capparidisine, capparisine, capprisinine and N-acetyl capparisine. Capparidisine has the molecular formula C27H33N3O6 (mol.wt. 495). It is a macrocyclic alkaloid containing two methoxylated and hydroxylated trans cinnamic acid residues which are linked to each other through oxygen bridge and to spermidine through amide bonds. Capparisine (C26H31N3O5) has the same skeletal system but one methoxy groups less than capparidisine. The third alkaloid capparisinine is an isomer of capparidisine with the methoxy group at different position. The fourth alkaloid is N-acetyl capparisine has molecular formula C28H33N3O6. The structure of these alkaloids were elucidated by means of modern spectroscopic methoas including UV, IR, Mass and NMR (1H, 13C and 2D) as well as through chemical studies.
