title: Triterpenes from the combined leaf and stem of Lithospermum caroliniense.
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 1 alpha,3 beta,23-trihydroxyolean-12-ene-28-oic acid and 3 alpha,19 beta,21 alpha,23-tetrahydroxytaraxast-12-ene-28-oic acid.
