HPLC–UV-HRMS/MS and NMR characterization of the isolated (9S)-HHC and (9R)-HHC. HPLC–UV trace of (9S)-HHC (a) and (9R)-HHC (b) with the respective UV spectrum in the boxes; HRMS/MS pattern in HESI + mode of (9S)-HHC (c) and (9R)-HHC (d) (the discriminant fragment is circled in blue and red for (9S)-HHC and (9R)-HHC respectively); HRMS/MS pattern in HESI- mode of (9S)-HHC (e) and (9R)-HHC (f); discriminant chemical shifts in the 1H NMR spectra of (9S)-HHC (blue) and (9R)-HHC (red) (g).
