The methods described here concern compounds that can be operationally defined as marine lipids. The basis of this definition is their amenability to liquid-liquid extraction in non-polar organic solvents, which provides a convenient means of sepa

This protocol is for the determination of lipids in seawater and biological specimens. Lipids in filtrates are extracted with chloroform or mixtures of chloroform and methanol in the case of solids. Lipid classes are measured by rod thin-layer chromatography with flame ionization detection and their sum gives the total lipid content.
