    • GC conditions: GC analyses were performed on a Shimadzu GC-1700 (Shimadzu Co., Japan) equipped with a flame ionization detector and a splitless injector. The injector temperature was 250 °C, and samples were injected manually (1 μL). The capillary columns used were DB-23 {(50% cyanopropyl) - methylpolysiloxane, Agilent J&W} 30 m × 0.25 mm, with a film thickness of 0.25 μm. The temperature was maintained at 50 C for 1 min, increased from 50 °C to 170 °C at a rate of 10 °C/min, and then increased from 170 °C to 210 °C at a rate of 1.2 °C/min. Helium was used as the carrier gas at a flow rate of 1.5 mL/min. The detector temperature was 250 °C.

    • GC-MS conditions: GC-MS experiments were performed on a Shimadzu GCMS-QP2010 (Shimadzu Co., Japan) equipped with a flame ionization detector and a split injector. The injector temperature was set at 280 °C, and samples were injected with a split ratio of 5:1. The capillary columns used were DB-5 ms (Phenyl Arylene polymer, Agilent J&W) 30 m × 0.25 mm, with a film thickness of 0.25 μm. The temperature program consisted of an increase from 100 C to 300 °C at a rate of 7 C/min and holding at 300 °C for 10 min. Helium was used as the carrier gas at a flow rate of 1.33 mL/min. Ionization of the GC eluent was performed using the electron ionization (EI) technique at 1.1 kV. The MS ion source temperature was set at 250 °C and the interface temperature was set at 280 °C. Under these conditions, the pyrrolidine derivatives of cis-vaccenic acid and cis-palmitoleic acid were eluted at 27.4 min and 25.1 min, respectively.
