(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-dihydrophenanthrene(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).展开更多

文摘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-dihydrophenanthrene(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).
