Abstract

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

Key words

Euphorbia sieboldiana - Euphorbiaceae - diterpenes - 3β-O-acetyl-ent-atisane-16α,17-diol - ingenol-20-palmitate
