Abstract
Bloodroot (Haemodorum spicatum) is an Australian native bulb plant yielding red pigment. This study aimed to characterize the phenolic and carotenoid profiles of the 80% ethanol extract of the H. spicatum bulb by HPLC-DAD-ESI-QTOF-MS/MS and HPLC-DAD. Results revealed the relatively low total phenolic content and antioxidant activity of the bulb extract with the maximum absorbance at 477 nm. Only 2 carotenoids (lutein and capsanthin) were detected at relatively low levels in the extract. A total of 40 phenolic compounds were tentatively identified, including 5 phenolic acids, 13 flavonoids and 22 other phenolic compounds, where 35 were reported for the first time in H. spicatum, together with 3 previously reported phenylphenalenones, haemodorol, haemoxiphidone and 2,5,6-trimethoxy-9-phenyl-1H-phenalen-1-one, and 2 oxabenzochrysenones, 5-hydroxy-2-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one and 5-hydroxy-1H-naphtho[2,1,8-mna]xanthen-1-one. This study provided the most comprehensive phenolic and carotenoid profiles of H. spicatum up to date.
