“…Based on the fragments in previous literature, peak 2 was 1-O-caffeoylglycerol (m/z 253.07, 179.03, 161.02 and 135.04) [15]; peak 3, dicaffeoylglycerides (m/z 415.10, 253.07, 179.03 and 135.04) [16]; peak 4, 1,3-O-dicaffeoylglycerol (m/z 415.10, 253.07, 179.03, 161.02 and 135.04) [16]; peak 5, p-coumaroyl-caffeoylglycerol (m/z 399.10, 253.07, 179.03, 161.02 and 135.04) [17]; peak 6, feruloyl-caffeoylglycerol (m/z 429. 12, 253.07, 193.05, 161.02 and 134.03) [18]; peak 7, tricin (m/z 329.23, 314.04, 299.01 and 271.02) [19]; and peak 9, 9-hydroxyoctadecadienoic acid (9-HODE) (m/z 295.22, 277.21 and 171.10) [20], respectively. Among them, 1,3-O-dicaffeoylglycerol ( Figure 6B), tricin ( Figure 6C) and 9-HODE ( Figure 6D) were identified as major compounds.…”
