From the whole plants of Euphorbia petiolata, four new ingenane-type diterpenoids, 3,20-O-diacetylingenol 5-O-(2' E,4' Z)-tetradecadienoate (1), 5,20-O-diacetylingenol 3- O-(2' E,4' Z)-tetradecadienoate (2), ingenol 3-O-(2' E,4' Z)-tetradecadienoate (3), and 5,20-O-isopropylidenylingenol 3-O-(2' E,4' Z)-tetradecadienoate (4) were isolated. Their structures were elucidated by spectroscopic methods and chemical transformations. |
