Two new diterpenes from Euphorbia kansuensis.
Two new lathyrane diterpenes, 3beta,5alpha-dihydroxy-15beta-cinnamoyloxy-14-oxolathyra-6Z,12E -diene (1) and 3beta,5alpha,20-trihydroxy-15beta-cinnamoyloxy-14-oxolathyra-6Z,12E-diene (2), were isolated from the roots of Euphorbia kansuensis. Their structures were determined by spectroscopic methods.
