The sterol composition of two taxonomically related freshwater species, Diplodom patagonicus and Diplodom variabilis , respectively, from Lake Nahuel Huapi and the Río de la Plata river were studied by gas liquid chromatography and mass spectrometry. Cholesterol was the main sterol in both species and it was followed by 24‐methylcholesta‐5, 22‐dien‐3β‐ol, 24‐methylcholest‐5‐en‐3β‐ol, 24‐ethylcholesta‐5,22‐dien‐3β‐ol and 24‐ethylcholest‐5‐en‐3β‐ol. The river species collected within the proximity of marine influence showed less cholesterol and more 24‐methylcholesta‐5,22‐dienol, 24‐methylcholest‐5‐enol and 24‐ethylcholesta‐5,22‐dienol than the lake species.
