Abstract
Chemical investigations on the aerial parts of Carissa opaca resulted in the isolation and characterization of two new nor-triterpenoids (compounds 1 and 2) and a new sphingolipid (compound 3) together with six known compounds. The structures of all the isolates were established using spectral data. All the isolated compounds showed DPPH radical scavenging and enzyme inhibitory activities against enzymes acetylcholinesterase, butyrylcholinesterase, and lipoxygenase.
