FAMEs formed from the present FAs after derivatisation by TMSH were detected by GC-MS as in Figure 3. The following FAs were identified by GC-MS with a relative content (%) in each enriched extract given in the order of D6, CHM no. 2a, 2b, 12a and 12b: (1) nonanedioic acid (1.1; 4.1; 3.4;—; 3.8%), (2) tetradecanoic acid (1.0; 2.1; 1.0; —; 0.4%), (3) pentadecanoic acid (2.4; 1.5; 0.8;—; 0.9), (4) 9-hexadecenoic acid (1.5; 1.7; 0.4;—; 0.1%), (5) palmitic acid (61; 39; 74; 30; 37%) (6) linoleic acid (6.5; 8.9; 0.5; 36; 6.6%), (7) 9-octadecenoic acid (4.2; 8.2; 4.6; 17; 9.2%), (8) oleic acid (2.9; 1.6; 1.0;—; 2.6%), (9) octadecanoic acid (8.5; 4.5; 3.4; 2.6; 4.4%), (10) 13-phenyltridecanoic acid (3.4; 3.9; 0.5; 0.1; 2.6%), and (11) docosanoic acid (0.2; 0.9; 0.7;—; 0.3).
