Triterpenoïdes de Harpullia Cupanioïdes

Tree new triterpenoids have been isolated from acid hydrolyzate of the root bark saponin of Harpullia cupanioides Roxb.. Their structures have been established from spectral data as camelliagenin A 16-tiglate, camelliagenin A l6-β,β-dimethylacrylate and camelliagenin A 22-β, β-dimethylacrylate. Besides these, other polyhydroxy triterpenoids characterized as camelliagenin A 22-angelate, A1-barrigenol 22-angelate and A1-barrigenol 22-β, β-dimethylacrylate have also been isolated.
