MHz spectrometer, equipped with a 5-mm cryo-probe at 295 K, following the method described earlier. In brief, 580 µL of a mixture of CDCl3/DMSO-d6 (5:1 v/v) were added to ~ 20 µL extracted oil (as described in the previous section) and transferred to 5-mm NMR tubes (Bruker, Billerica, Massachusetts, USA). From the recorded single pulse experiment, the glycerol backbone peaks at δ 4.4 pm were used to quantify the amount of triacylglycerols.
