[Macrocyclic diterpene polyesters of the jatrophane type from Euphorbia esula].
Three new jatrophane diterpenes, esulatin A, B and C (1-3) were isolated and characterized from the whole, undried plant of Euphorbia esula. By means of spectral analysis, the structures were established as penta- and heptaesters of hitherto unknown, polyfunctional diterpene parent alcohols. Esulatin A (1) and C (3) are the diterpenoids with the highest degree of esterification identified to date from the family Euphorbiaceae.
