fruit consumed in Turkey. This study aimed to determine the content of total
phenolic, total flavonoid and antioxidant activity of <i>Punica granatum </i>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 </span> <span lang="it" style="font-size:10pt;line-height:150%;font-family:Verdana, ’sans-serif’;" xml:lang="it">flavonoids </span> <span lang="en-us" style="font-size:10pt;line-height:150%;font-family:Verdana, ’sans-serif’;" xml:lang="en-us">
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 <i>Punica
granatum </i>L. flower might be, at least in part, due to the existence of high
content of flavonoids compounds and other phenolics.   </span> <span lang="en-us" xml:lang="en-us"> </span> </p> <p> </p>}, number={1}, publisher={Turkish Chemical Society}
