Abstract

Betacyanins in peel and flesh of fruits of different Hylocereus species were identified by means of GC/MS, electrospray MS/MS, HPLC as well as 1H and 13C NMR techniques. As hitherto unknown pigments: betanidin 5-O-(2′-O-β-d-apiofuranosyl)-β-d-glucopyranoside, betanidin 5-O-(4′-O-malonyl)-β-d-glucopyranoside and betanidin 5-O-[(5″-O-E-sinapoyl)-2′-O-β-d-apiofuranosyl]-β-d-glucopyranoside were elucidated. The sinapoyl moiety attachment position in the structure of betacyanins was established for the first time. The peel contained a more complex pattern of betacyanins with apiofuranosyl moiety. Other recently identified pigments were also present in the samples and their 1H or 13C NMR spectra were recorded. In the case of phyllocactin and its 4′-isomer the migration of the malonyl group was noticed.
