Food and Machinery
The ethanol extracts of flowers from Abelmoschus manihot was extracted by petroleum ether、ethyl acetate and n-butyl alcohol, and four different polar portions were obtained. The scavenging effect of different phases on DPPH·, ·OH and H2O2 were studied to research the antioxidant activities of each phase. Moreover, the protection of n-butyl alcohol phase on DNA oxidative damage was also studied, and the flavonoids component was identified by HPLC-MS. The results showed that the ethyl acetate phase had the best scavenging effect on DPPH·, with IC50 value 0.038 6 mg/mL. However, the n-butyl alcohol phase had scavenge ·OH …
