A method based on normal-phase high performance liquid chromatography combined with evaporative light-scattering detector was developed to quantify major neutral lipids from microalgae. A binary gradient enabled a good resolution of hydrocarbons and major neutral lipids by classes in less than 13 min. A good linearity was observed from 0.9 to 30 μg. Limits of detection (LOD) and quantification (LOQ) was from 3 to 64 ng depending on the analyte. The intra- and inter-run precision (% RSD) of analysis was found less than 10%. The method was successfully applied to microalgae lipid extracts from Botryococcus braunii, Chlorella vulgaris, Spirulina platensis, and Porphyridium cruentum. B. braunii was distinguished by the highest levels of lipids, triacylglycerol (TAGs), and diacylglycerol (DAGs) being the major compounds.
