Two new diterpene polyesters from Euphorbia decipiens.
Two new myrsinol-type diterpene polyesters 3,5,13,17-tetra- O -acetyl-7- O -benzoyl-15-hydroxymyrsinol ( 1 ) and 3,5,13,17-tetra- O -acetyl-7- O -butanoyl-13-hydroxymyrsinol ( 2 ), with a tricyclic carbon skeleton have been isolated from Euphorbia decipiens Boiss. & Buhse.

| Sumario: | Two new myrsinol-type diterpene polyesters 3,5,13,17-tetra- O -acetyl-7- O -benzoyl-15-hydroxymyrsinol ( 1 ) and 3,5,13,17-tetra- O -acetyl-7- O -butanoyl-13-hydroxymyrsinol ( 2 ), with a tricyclic carbon skeleton have been isolated from Euphorbia decipiens Boiss. & Buhse. The structure elucidation of the isolated compounds was based primarily on HREIMS, EIMS, IR, UV, 1D-, and 2D-NMR analyses, including COSY, HMQC, HMBC, and NOESY correlations. Compounds 1 and 2 also showed activity against urease enzyme. |
