Abstract: Two novel triterpenes (1 and 2) were isolated from the orchid Pholidota yunnanensis Rolfe. Using chemical and spectral analyses (UV, IR, MS,1D-NMR and 2D-NMR), these two triterpenes were established as 25-methylenecyclopholidonyl p-hydroxy-trans-cinnamate (1; named pholidotine A) and 25-methylenecyclopholidonyl p-hydroxy-cis-cinnamate (2; named pholidotine B).

Key words: Orchidaceae, Pholidota yunnanensis Rolfe, pholidotine A, pholidotine B.
