Two new jatrophane diterpenoids, esulatin D and E, have been isolated from the dichloromethane extract of the whole, undried plant of Euphorbia esula. The structures have been assigned on the basis of spectral analysis, including 2D NMR experiments. (C) 1998 Elsevier Science Ltd. All rights reserved.
