Pomegranate is one of the most abundant
fruit consumed in Turkey. This study aimed to determine the content of total
phenolic, total flavonoid and antioxidant activity of Punica granatum L.
flower in different extracts. Antioxidant activities of different extracts were
determined 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging, reducing
power and metal chelating methods. The result showed that, total phenolic
content for the extracts was ranged from 14.82 to 90.86 mg gallic acid
equivalents(GAE) / g extract. The contents of flavonoids were found to range
from 7.35 to 500.00 mg quercetin equivalents (QUE)/ g extract. All pomegranate
flower extracts displayed remarkable antioxidant activity according to DPPH and
reducing power assays. Especially the methanolic extract of pomegranate flower
possesses significant scavenging activity against DPPH• (85.80 %), as well as
the largest contents of flavonoids
and phenolic compounds. The antioxidant capacity of the methanolic extract was
also greater than those of BHT and α-tocopherol in DPPH and reducing power
assays. The results demonstrated that the antioxidant activity of extracts of Punica
granatum L. flower might be, at least in part, due to the existence of high
content of flavonoids compounds and other phenolics.
