Abstract

Cydonia oblonga is a fruit tree of the Rosaceae family. The objective of this study is the evaluation by spectrophotometric assay, of polyphenols and flavonoids as well as the antioxidant activity by DPPH scavenging tests, of the flowers of Cydonia oblongafrom eastern Algeria. The determination of the total phenolic contents, shows that the highest content was measured for the methanolic extract, with a value of 135.50±1.21 mg GAE/g, followed by the ethanolic extracts, with a value of 75.25±0.9 mg GAE/g. The determination of the total flavonoids shows that the highest content was measured for the methanolic extract, with a value of 209.69 ±2.42 mg CE/g followed by the ethanolic extract with a value of 174.67± 1.81 mg CE/g. In antioxidant measurement the methanol extract have ,the higher percentage of DPPH inhibition with the IC50 equal to 1.70± 0.26 mg/ml, followed by ethanolic extract with value 2.50±0.38 mg/ml.The results showed that the methanolic extract had a highest amount, of total phenol and total flavonoid which by consequently gives it the highest antioxidant activity.
