摘要：

Two dihydrophenanthropyrans, shanciol E and F, and two bibenzyls, bulbocodin C and D, were isolated from tubers of Pleione bulbocodioides. The new structures were elucidated to be 3-hydroxy-11-methoxy-2-(4'-hydroxy-3',5'-dimethoxyphenyl)-2,3,5,6-tetrahydro-4H-phenoanthro[2,1-b] pyran-8-ol; 4-hydroxy-11-methoxy-3-(4'-hydroxy-3-methoxyphenyl)-3,4,5,6-tetrahydro-2H-pehnanthro[2,1-b] pyran-8-ol; 3',5-dihydroxy-3-methoxy-2,4-di(p-hydroxybenzyl)bibenzyl; 3,3'-dihydroxy-5-methoxy-2,4-di(p-hydroxybenzyl)bibenzyl benzyl; respectively, on the basis of spectroscopic data and chemical correlations.
