Abstract
An investigation of the combined leaf and stem of Lithospermum caroliniense afforded two new pentacyclic triterpenoids based on the olean-12-ene and taraxast-12-ene skeletal types. The structures of these compounds were elucidated on the basis of spectral analysis as 1α,3β,23-trihydroxyolean-12-ene-28-oic acid and 3α,19β,21α,23-tetrahydroxytaraxast-12-ene-28-oic acid.
