title: Phenanthrene and phenylpropanoid constituents from the roots of Cymbidium Great Flower 'Marylaurencin' and their antimicrobial activity.
abstract: Two new phenanthrenes, and one new phenylpropanoid, named ephemeranthoquinone C (1), and marylaurencinols C (2) and D (3), were isolated from the roots of Cymbidium Great Flower 'Marylaurencin', respectively. These structures were determined on the basis of 2D NMR experiments. The compounds were tested for antimicrobial activity against Bacillus subtilis, Klebsiella pneumoniae, and Trichophyton rubrum.
