Diterpene polyesters from euphorbia seguieriana
An Me2CO extract of Euphorbia seguieriana (Euphorbiaceae) afforded seven new diterpene polyesters (1-7). Five of them (1-5), having a new parent alcohol that was named 17-hydroxymyrsinol, were structurally related to myrsinol. The other two compounds (6, 7) were new derivatives of the known parent alcohols cyclomyrsinol and lathyrane. The structure elucidations of the new compounds by highfield spectroscopic methods, including 1D and 2D NMR techniques, are described.
