title: Chemical Constituents from the Aerial Parts of Cyrtopodium paniculatum.
abstract: We report the first phytochemical study of the neotropical orchidCyrtopodium paniculatum. Eight new compounds, including one phenanthrene1, one 9,10-dihydro-phenanthrene2, one hydroxybenzylphenanthrene3, two biphenanthrenes4-5, and three 9,10 dihydrophenanthrofurans6-8, together with 28 known phenolic compounds, mostly stilbenoids, were isolated from the CH₂Cl₂ extract of its leaves and pseudobulbs. The structures of the new compounds were established on the basis of extensive spectroscopic methods.
