title: [Chemical constituents from Pleione bulbocodioides].
abstract: Fourteen compoumds were isolated from the ethyl acetate portion of the 95% ethanolic extract of Pleione bulbocodioides by a combination of various chromatographic techniques including silica gel, ODS, macroporous adsorbent resin, Sephadex LH-20, and preparative HPLC, of which ten compoumds were phenanthrenes and dihydrophenanthrenes, two compoumds were bibenzyls, one was lignan and a sterol. Their structures were identified on the basis of spectroscopic data as monbarbatain A(1), 2, 7, 2'-trihy-droxy-4, 4', 7'-trimethoxy-1, 1'- biphenanthrene(2), blestriarene A(3), pleionesin B(4), shanciol H(5), 17-hydroxy-7'-(4'-hy-droxy-3 '-methoxyphenyl)- 4-methoxy-9, 10, 7', 8'-tetrahydrophenanthro[2, 3-b]furan-8'-yl methyl acetate(6), 1-p-hydroxybenzyl-4-methoxy phenanthrene-2, 7-diol(7), 1-p-hydroxybenzyl-4-met-hoxy-9, 10-dihydrophenanthrene-2, 7-diol(8), hircinol(9), coelonin( 10), gigantol(11), batatasin 11 (12), syringaresinol(13) and ergosta4, 6, 8 ( 14) , 22-tetraen-3-one (14). Compounds 1-3, 9, 13 and 14 were isolated from this genus for the first time.
