Three new phenanthraquinones, phenanobiles A~C (1~3), together with two known phenanthraquinones 6,7-dihydroxy-2-methoxy-1,4-phenanthrenedione (4) and ephemeranthoquinone (5), were isolated from the root of Dendrobium nobile. Their structures were elucidated using comprehensive spectroscopic methods. The antitumor activities of compounds 1~5 were evaluated against three cancer cell lines (HL-60, A549 and MCF-7). Compounds 1~5 exhibited inhibitory effects against three cancer cell lines HeLa, MCF-7 and A549in vitro.
Key words: Dendrobium; Dendrobium nobile; phenanthraquinone; antitumor activity
