Total ion chromatogram of the gas chromatographic enantiomer separation of 14 on a chiral β-TBDMS-hydrodex phase. Temperature program: isothermal for 60 min at 110 °C, then with 2 °C/min to 160 °C, followed by a sharp ramp of 25 °C/min to 220 °C. (A) racemic mixture; (B) S-14; (C) R-14; (D) natural extract of a gland extract of H. cinnamomeoventris; (E) coinjection of the natural extract and S-14. Peak identities were confirmed by GC/MS.
