1 M sodium methoxide in methanol. The resulting FAMEs were extracted with hexane (3 mL) and washed with water (10 mL), and then 1 μL of FAMEs was injected to a GC (Hewlett-Packard
5890 Series II, Pa., U.S.A.) equipped with a SPB-2330 fused silica column (15 m × 0.25 mm × 0.20 μm, Supelco, Bellefonte, Pa.). The injector and flame ionization detector were set at 230 ◦C, and
