Abstract:
Two new diterpenoid acids were obtained from the traditional Chinese medicinal herb Pinus koraiensis. By spectral evidence, the structure of the new compounds were elucidated as 7-oxo-13beta,15-dihydroxyabiet-8(14)-en-18-oic acid (1) and 7-oxo-12alpha, 13beta,15-trihydroxyabiet-8(14)-en-18-oic acid (2), respectively.
