Abstract:
:From the pro-inflammatory active extract of Euphorbia peplus, a new diterpene polyester (1) based on the jatrophane skeleton was isolated together with the known compounds 2-5. The irritant activities of some jatrophane diterpenes (2, 3 and 6-9) were also investigated: only compound 2 was found to exert a weak pro-inflammatory activity on mouse ear.
