A compilation of the C-13 NMR data of a selected variety of naturally
occurring pentacyclic triterpenoids, arranged skeletonwise, is provide
d. A brief account of the newer signal assignment techniques and a dis
cussion on the substituent effects on the C-13 shieldings of the trite
rpenoids, are also included.
