| Abstract: | Two novel diterpene dimers with a bismagdalenic acid skeleton, bisyinshanic acids A and B ( 1 and 2 , resp.), along with eight known diterpenoids ( 3 – 10 ), were isolated from the roots of Euphorbia yinshanica. Their structures were elucidated on the basis of spectroscopic evidence. |
