Three novel 24,30-dinortriterpenoids, paeonenoides A-C, from Paeonia veitchii

摘要

Three novel 24,30-dinortriterpenoids named paeonenoides A-C (1-3) and the four related acetonide derivatives 4-7, most likely artifacts of isolation, together with a known triterpenoid, akebonic acid (8), were isolated from the root cortex of Paeonia veitchii. Their structures were established by spectroscopic means. The 24,30-dinor skeleton of triterpenoids occurs rarely in nature.
