Two new stilbenoids fromPleione bulbocodioides

Abstract
Two new stilbenoids, 9-(4′-hydroxy-3′-methoxyphenyl)-10-(hydroxymethyl)-11-methoxy-5,6,9,10-tetrahydrophenanthro[2,3-b]furan-3-ol (1) and 2-(4″-hydroxybenzyl)-3-(3′-hydroxyphenethyl)-5-methoxy-cyclohexa-2,5-diene-1,4-dione (2), together with the three known stilbenoids were isolated from the tubers of Pleione bulbocodioides (Franch.) Rolfe. Their structures were elucidated by spectroscopic methods.
