摘要：

A novel dihydrophenanthropyran, shanciol was isolated from tubers of Pleione bulbocodioides, together with the known compound bletilol B. The structure of the new compound was elucidated as 3-hydroxy-11-methoxy-2-(4'-hydroxy-3'-methoxy-phenyl)-3,4, 5,6-tetrahydro-4H-phenanthro [2,1-b]pyran-8-ol on the basis of spectroscopic data and X-ray analysis. Furthermore, the absolute configurations of bletilol B were determined to be 11S and 12S by means of Horeau's partial resolution method and chemical correlations.
