Three new monophenanthrene compounds were isolated from an acetone extract of the tubers of Monomeria barbata Lindl. (Orchidaceae). Using spectroscopic methods, the structures of compounds 1-3 were determined as 1,4,7-trihydroxy-2-methoxy-9,10-dihydrophenanthrene (1), 1-(p-hydroxybenzoyl)-2-methoxy-4,7-dihydroxy-9,10-dihydrophenunthrene (2), 1,3,8-tri(p-hydroxybenzyl)-4-methoxy-phenanthrene-4,7-diol (3). These compounds showed cytotoxicities on four tumor cell lines (HepG2, HL-60, Skov-3, A431).
