| Abstract: | 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).
