Analyses compare gas-liquid chromatography methods for determining sphingosine bases, suggesting optimal identification techniques.

This research aims to compare different analytical methods for identifying sphingosine bases in sphingolipids.
Compared permanganate-periodate oxidation, periodate oxidation, and trimethylsilylation methods.
Used authentic dihydrosphingosine and isolated cerebroside from pig brain along with yeast powder sphingolipids.
Analyzed shorter chain homologs of sphingosine bases.
Trimethylsilylation method was best for qualitative analysis of sphingosine bases.
Periodate oxidation provided reliable quantitative results for sphingosine base composition.
C16-sphingosine and C16-dihydrosphingosine were found at low levels in pig brain cerebroside.

Akino Toyoaki (1969) studied this question.
