Eight non-irritant macrocyclic diterpene esters of the jatrophane type were obtained from an irritant acetone extract of latex and from an irritant methanol extract of roots of E. characias. They were shown to be diesters of the new parent alcohols characiol, characiol-5.beta.,6.beta.-oxide and 5.beta.-hydroxyisocharaciol, and pentaesters of 2,5.beta.,8-trihydroxyisocharaciol.
