Easy ambient sonic‐spray ionization mass spectrometry (EASI–MS) was used to follow the maturation of Jatropha curcas L. seeds via the monitoring of the triacylglycerides (TAG) profile of the oil. Results show that TAG composition is significantly modified during seed development but remains nearly unchanged during storage. The EASI–MS oil analysis performed herein is simple, requires just a tiny droplet of the oil and is performed without any pre‐separation or chemical manipulation. The oil from Jatropha gossypifolia L. was also evaluated, and a very different TAG profile was obtained.
