Two new tigliane diterpene esters from the flower buds of Daphne genkwa.


PMID 23600859

Abstract

The phytochemical investigation of the flower buds of Daphne genkwa yielded four highly oxygenated tigliane diterpene esters (1-4), including two new phorbol derivatives, 12-O-(2'E,4'E-decadienoyl)-7-oxo-5-ene-phorbol-13-acetate (1) and 12-O-neodecanoyl-7-oxo-5-ene-phorbol-13-acetate (2). The molecular structures of the isolated compounds were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2D NMR.
