From the acetone extract of roots of EUPHORBIA SIEBOLDIANA, three known diterpenes, ENT-atisane-3beta,16alpha,17-triol ( 1), ingenol ( 4), and helioscopinolide A ( 5) as well as two new diterpenes, 3beta- O-acetyl- ENT-atisane-16alpha,17-diol ( 2), and ingenol-20-palmitate ( 3) were isolated. Their structures were elucidated by spectroscopic methods and chemical transformations. |
