New Fatty Acids from the Leaves of Vernicia fordii

Two new conjugated ketonic fatty acids, (10E,12E)-ethyl 9-oxo-octadeca-10,12-dienoate (1) and (14S)-(10E,12E)-methyl 14-hydroxy-9-oxo-octadeca-10,12-dienoate (2), were isolated from the leaves of Vernicia fordii collected from Hunan Province of China. Their structures were characterized by means of spectroscopic analyses. All of them were tested for their cytotoxicity against five human cancer cell lines.
