Abstract
A new norditerpenyl eater, named Calotropterpenyl ester, and two unknown pe ntacyclic triterpenoids, namely calotropur senyl acetate and calotropfriede lenyl acetate have been isolated from the root bark of Calotropis procera. Their structures have been established as 6,10,14-trimethylpentadec-6-enyl- 2', 4', 8', 12', 16'-pentamethyl nonadecane ester, urs-12,19(29)-diene-3 be ta -yl acetate and friedelin-1-ene-3 beta -yl acetate, respectively, on the basis of spectral data analyses and chemical reactions.
