Thermally assisted hydrolysis and methylation-gas chromatography (THM-GC) in the presence of trimethylsulfonium hydroxide, using a vertical microfurnace pyrolyzer, was validated for the compositional analysis of fatty acid components in microalgae. The chromatograms of a microalga Pavlova lutheri obtained under optimized THM conditions clearly showed a series of fatty acid methyl esters including thermally-labile polyunsaturated fatty acid components. Based on these peak areas, their chemical compositions were rapidly determined without using any tedious sample pretreatment with a precision of less than 8% relative standard deviation. Moreover, the compositions thus obtained were in good agreement with those obtained by the conventional technique involving solvent extraction. Finally, the THM-GC technique was applied for the compositional analysis of fatty acid components in a newly found microalga, C. gloeobotrydiformis. The obtained data showed a high abundance (24 mol%) of α-linolenic acid components, suggesting its potential usefulness as feed sources and/or functional foods.
