Reversed phase liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (RP-HPLC/APCI-MS) was used for direct analysis of triacylglycerols (TAGS) from different strains of the cyanobacteria Mastigocladus laminosus, Tolypothrix cf tenuis and Tolypothrix distort. This technique enabled us to identify and quantify the specific molecular species of TAGs directly from lipid extracts of the cyanobacteria. The regioisomeric series of TAGs having alpha-linolenic and gamma-linolenic and also oleic and cis-vaccenic acids were separated by RP-HPLC and identified by APCI-MS
