The (22R)-30a,30b-dihomohopan-30b-yl and tetrahymanyl esters of pyrophaeophorbide a, chlorophyll a transformationproducts resulting from zooplankton herbivory, occur in an extract of surface sediment from Lake Valencia (Venezuela). The former was identified by HPLC-PDA-MS comparison with a standard and the latter after reduction of the extract and GC-MS analysis of the released alcohols.
