- Abstract
Two new ent-labdane diterpenes, ent-3 α,16-dihydroxylabda-8(17),12( E),14-triene ( 1) and ent-14( S),15-dihydroxylabda-8(17)-12( E)-dien-18-oic acid ( 2), were isolated from the roots of Euphorbia yinshanica. Their structures were elucidated on the basis of spectroscopic methods including HR-ESI-MS and 1D and 2D NMR. The cytotoxic activities against five tumor cell lines was also evaluated, but there was no significant activity.
