3.5. Determination of the Triacylglycerols (TAG) Content
The triacylglycerols (TAG) content of pine nut oils are given in Table 4 and their HPLC chromatogram is given in Figure 3.
In our study, 9 kinds of TAG were determined and the most abundant TAG was found to be LLL (trilinolein) with the TAG quantity of 11.5867% in total crude oil. It was followed by OLnL (Oleolinolenolinolein) (0.7302%), PLnL (Palmitolinolenolinolein) (0.1422%) and PoLL (Palmitoleodilinolein) (0.0826%), respectively. Similar to the results in our study, Nergiz and Dönmez, 2014 investigated the TAGs of some pine nuts with an ECN of 42 and LLL (10.8%) was found to be the predominant TAG followed by OLnL (2.23%) and PLnL (0.83%), respectively [23]. In another study, 3 kinds of TAG with an ECN of 42 were analyzed and the most abundant TAG was found to be LLL (12.96%) followed by OLnL (2.10%) and PLnL (0.65%), respectively [18]. Previous studies are very close to our study in terms of triacylglycerol content of pine nut oil.
