Observations concerning the Specificity of the Acid Haematein Test for Phospholipines

Studies with synthetic enantiomeric a-phosphatidic acids,{alpha}-phospholipines, and related compounds, and with highly purified, natural lipine fractions confirm that Baker’s ‘acid haematein test (controlled by the pyridine extraction test) is a method for the histochemical recognition not of lipine in general, but of phospholipine’. A true positive reaction is also given by certain phosphatidic acids.
