In addition to reported 17,14-friedolanostane type (I) of triterpene further triterpenes having new rearranged lanostane skeletons, 17,13-friedolanostane (II) and 8(14→13R)abeo-17,13-friedolanostane (III), have been isolated from the seed of Abiesmariesii. The skeletons I and II were also found to occur in A.firma. Their structures have been elucidated by spectral and X-ray diffraction analyses.
