An improved method for the hydrolysis of long chain bases from gangliosides with aqueous acetonitrile-HCl is described. The long chain bases released from brain gangliosides were derivatized with biphenylcarbonylchloride and resolved by high performance liquid chromatography on a C18 reversed-phase column. Components of individual peaks were identified by gas-liquid chromatography-mass spectrometry as their trimethylsilyl derivatives. The acetonitrile-HCL hydrolysis procedure resulted in no formation of O-methyl ethers of long chain bases and a significant decrease in the level of secondary products.
