Abstract
Summary
Freeze-dried chloroform-methanol extracted samples of human cerebrospinal fluid (CSF) were examined for various lipids by means of paper chromatography. Phosphatidyl ethanolamine and ethanolamine plasmalogen were characteristically high as compared with blood plasma. Sphingomyelin, phosphatidyl choline and a small amount of choline plasmalogen were also present. The neutral lipids were composed of triglycerides, cholesterol and cholesterol ester. A plasmalogen resembling cardiolipin was present in low concentration. The cerebrosides were not detected.
