Unique Identifier : AIDSLINE MED/95306027 AB The Turkish species Euphorbia myrsinites has yielded four new tetracyclic diterpene tetraesters from a cytotoxic acetone extract, in addition to the known cycloartane-type triterpenoids and betulin. The new compounds and their hydrolysis product have been extensively characterized by high field spectroscopic techniques, and were shown to be four new tetraesters of the parent alcohol, myrsinol.
