title: [Isolation and structure elucidation of three dihydrophenanthrenes from Ephemerantha lonchophylla].
abstract: In this paper, three dihydrophenanthrenes are isolated from the Stems and pseudobulbs of Ephemerantha lonchophylla (Orchidaceae). They are identified as Iusianthridin (1), ephemeranthol-B (2) and erianthridin (3) by spectral data.
