Bioactivity-guided fractionation of the latex of Euphorbia poisonii Pax. (Euphorbiaceae) led to the isolation and characterization of a new tigliane diterpene, 12-deoxyphorbol 13-(9,10-methylene)undecanoate (3), together with five known diterpenes (1, 2, 4−6).
Euphorbia tirucalli L. is an important tree Euphorbia species, known for its many uses in the tropics. Endemic to tropical eastern Africa where it often grows wild, it is usually planted for boundary demarcation but also as a live fence around compounds, shrines and kraals.
